The Differences Between 19" & 20" and 20" & 21" Wheels Tested! [Michelin Pilot Sport 4 S NAO]
HTML-код
- Опубликовано: 4 июл 2024
- Have you ever wondered what difference ticking the big wheel size option makes when specifying your new car? In this video I find out! I use a new Porsche 992 911 which comes standard with 19" front and 20" rear wheels, and test them against the optional 20" front and 21" rear wheels!
Both these wheel options use the new Michelin Pilot Sport 4S NA0 tire which is specifically designed for the 992 911. The standard tire sizes are 235/40 R19 front and 295/35 R20 rear and the optional big wheel size is 245/35 R20 front and 305/30 R21 rear.
As usual I test the braking performance in the dry and wet, dry lap time, wet lap time and look at the noise and comfort of the two different sets of wheels.
Does fitting big wheels to your car really ruin the handling? Do big wheels make you faster around a track? Only one way to find out! Lets get testing.

![This Is Why You Should Fit OE Tires To Your Car! [Michelin Pilot Sport 4S vs 4S*]](http://i.ytimg.com/vi/COA630Juf_U/mqdefault.jpg)
I’m not a prolific RUclips commentator but I would love to let you know that your videos are extremely informative and appreciated. I just wish you did even more of them!
thanks :) I wish I did more too but I'm flat out as it is. Plenty to come for test of 2022!
I agree.. he should do more comparsing vids..
Exactly the same comment comes from me 👍
Note that the 19/20 has slightly less wide tires as well, which is likely what's making a big part of the differences between the sets
Also different compound very likely !
yeah it technically runs less camber and there's less surface area actually touching the ground
@@PainYT what do you mean by less (negative) camber ?
@@vollcare4076 he's trippin
I'd say yes for the difference in force to turn the steering wheel, maybe/partially for the lap times (the difference in contact patch is not nearly enough to explain the difference) and no for the handling characteristics, since the directness in feeling in transitions is probably 100% due to the narrower sidewall.
Those drifts on the wet track were so smooth! Thought I’d give you a like for that alone! Good work!
Just replaced my PS4S with the new SportContact 7 on the 272bhp 4x4 Superb (stage 2), following your recent test.
Wow, nearly eliminated the understeer completely.
And the ride quality is much smoother.
The tyres give a tremendous amount of confidence, the grip is unbelievable.
Thank U.
Glad you like them :) If you get some time please stick a review on www.tyrereviews.com :D
I have noticed that the SportContact (6 too) are better on "understeery" cars.
Wouldn't know. I was a Michelin believer, always replaced the tyres that came with the new cars (Bridgestone / Pirreli) , shortly after some 10K, and was appreciating the change.
Lately I started to think about Cup 2, though their short life kinda put me off.
It is my third 272/280 bhp 4x4 Superb and I drive very hard a 100 miles twisty roads twice a week, so I really can feel the change. The elimination of the understeer gives me an entirely new approach to my car, after I felt I had extracted everything I can with it.
And with it came a lively steering feedback.
Don't know, yet, how long will they stay effective...
Similar story here. Replaced the PS4S on my A4 2.0T quattro with SC7, both in 255/35/19 on 19x8.5 rims. In comparison the PS4S felt like they had lazy turn-in and a non-linear steering reponse that lead to wobbly steering inputs, trying to find the angle that matched the desired line at any given time and load and speed. The SC7 feel sharp and very linear and feel like they load up much quicker, with very smooth steering. Subjectively, I'd also say the SC7 are more comfortable, even though some reviews rate the SC7 below the PS4S in that regard.
@@guytaglit9440 yeah you don't put cup 2 on a skoda superb, it isn't focused for track sportiness. If I had a superb, I'd get a PS4, P Zero LS, or premium contact or goodyear asymmetric 6
Wife picked the biggest AMG wheels for my wife's Merc. I've had two wheels repaired already. Never again.
I'd suggest you trade them for a smaller sized set of wheels😁
@@n.r.c.w She likes her 20 spoke 21" wheels. She likes curbing them too.
Happy wife, happy life. ^^
@@n.r.c.w Trade his two wives for a set of wheels???
@@gwcrispi Perfect match- Repair shop
For everyday use the "small" option is the better compromise.
Less unsuspended masses, quicker into rotation... ;)
And it is like with racing tires: if Michelin is doing something for Porsche you can't beat them.
It was a very impressive test! 🏆 I'm not quite sure it answered the question if 20" on your Volvo XC40 or 22" on your Volvo XC90 are worth it, mind you? 🤔😂
@@TassieLorenzo tyres sure are expensive for pirelli if you have an XC90 with 22" wheels
Agree 100%. Generally, bigger wheels are about appearance when parked, not grip, handling, braking or ride.
@@54mgtf22 bigger wheels with always ruin the ride. I've got 215/55/17 it's like a magic carpet. Obviously 235/40/19 would look cooler.
Really interesting video again buddy, not much between them at all! And what a car the 992 is 🙌
awesome video, i love how this tyre/wheel size comparison/review became a song of praise for 911 in no time at all. what a great car, thank you for the content.
Glad you enjoyed it!
Always gone for the smallest possible wheel size when I've had the choice and I've never regretted it 👍
I had many tyres from 165/55 R13 to 245/35 R19 and never regretted it. On one car I had stock 185/55 R15 and went up to 225/35 R18 and didn't regret anything. What's your point?
If you don’t care about aesthetics then yea
18's on gr4 has great turning circle.
19's on previous i30N performance pack and seat Leon cupra R 265 2011 before that was SHITE!
18'S on Octavia vrs tfsi before that was far better again, vs 19's.
Never been higher, but looking back over the last 30 years of driving, personally I think, when it comes to tyres/wheels, small is actually better 😉🙃
@@James-RJM 100% same opinion
@@dimmacommunication 😉🙂👌👍
Love your videos! As you say don't expect this level of engineering and thought when you order the big rims on your run of the mill hatchback but it's great to learn about what goes in at a Porsche-Michelin sorta level, and it follows on well from you 17/18/19 video as well as your video on OE-spec tires! I'm a Matt Farah/TheSmokingTire fan and he often asks if anyone does tire testing like you do and I say YES TYRE REVIEWS DOES! One of my weird little YT-based dreams is to see you as a guest on the TST podcast I have this weird feeling you would two would get on well and you'd be a very interesting guest!
From my past experience in motorsport, generally you chose smallest possible rim to fit over a brake and most rubber you can get within race rules. This was always amplified by single seaters that could preheat brakes and go for ceramics to have tiny rims. Of course, then comes how suspension is designed, because if engineering team knows that users will always chose stupid big rims, they will setup suspension with large rim bias. So I'm not surprised that in car aimed towards vanity larger rims perform better. Now on normal roads, more rubber would soak up imperfections better and would be more controllable - but again, there are so many variables, that it's impossible to define a all time winner for all.
What most of "racers" miss, is that driving pressure != racing pressure, and that damage handling more than putting snows on.
Thanks for the nice vid, keep up the good job !
Tire Rack testing showed that generally running a smaller tire rather than bigger was quicker around the track if wheel width didn't change
Sure you may be using a base spec car in the video but your driving skills will absolutely maximize the capabilities of the car you're driving. Well done!
Thank you :)
Jon. Really thank you for bring safety as the priority. Average road users know crap of safety... They look at what they can save
I love tires way more then I should and love you and your channel for it.
Great content - thanks. My dream set up would be the 992 GTS C4 with 19/20in running PS4S on the road and a spare set of wheels with 20/21in running PSCups for track days. The ultimate all-rounder.
I love how detailed all the videos are since years back (avid viewer) but there's constantly one thing missing: Pressures. I do presume all tire pressures are "oem stock/specified" for the car, but, that's very skewed when comparing UUHP tires, semi slicks etc, since it's no good anymore. You never ever mention tire pressures and how different it makes breaking, dry and wet grip in tests where it's relevant :( Us tyre nerds know how vital pressures are, not strictly for track even, please include pressure info front/Rear and i'd love a pressure-oriented video for the main top pick tyres, to show people how much the sidewall, feel, grip, changes with just 2-5psi differences, and also temperatures. Car's balance can be changed so much with a slight pressure change too, from over/understeer but maybe it's all suppose to be according to specification? I'd love to have comments on pressures in every video. "We're sticking to OEM pressures in this test" or "It's a bit understeery but 0.1 Bar increased rear neutralizes the balance" etc....
It's certainly on the list to do, but a very complicated subject! And you're right, we always use OE pressures unless stated
@@tyrereviews Yeah I reckon! Thanks for the reply! Struck my mind when watching the trackday test that basically neither of those tyres want "oem" pressures and pressure diffences make such a difference to mainly feel (in the softer sidewalled brands) while some keep their grip levels when going a few psi above stock. Aaaand how heat affects the tyre depending on pressures! But most of these notes are for the UUHP/road legal semi slicks of course. Cheers!
The authority on tyres as usual. Thank you! 😏
Awesome vid! Always interesting the inch differences. Like new Civic type r going 19" from 20" in old one
I didn't realise they'd dropped a wheel size!
Great test. When I mentioned your reviews to a Michelin test driver he maybe said good job as well.
Would you please consider doing a video on what you notice when replacing JUST the rear tires on a rwd car and keeping tires on the front that are 30k kms old? When replacing tires on a rwd car, what is the best to do? Replace all four? Even if the fronts have a lot of life left?
And please compare different tread patterns on the front and rear when one is switching tire brands two tires at a time. Thank you. Always love your informative videos. I share the 17”, 18” and 19” comparison video of yours with people all the time. Most informative Tire reviews I’ve ever seen.
I think in a 911 a new tyre is always "relatively quiet". But once they wear they become more loud. Im sure the bigger wheel with smaller tyre wall height will become quite a bit more loud once worn out. The same goes with width and wet grip with wearing out. These UHP/UUHP tyres are superb in wet when new. Im not so sure about once the grooves have halved.
Anyway, thanks again for excellent content. You are one of the best in the RUclips, sort of the Rick Beato of tyres :))))
ps. What I'd really love is a comparison of the 996 C2 with the best tyre option and a 992 C2 with similarly the best tyre option from one make (probably Michelin). And it would be great to see the difference between, say PS2 and PS4S in a direct comparison with almost any car you could do it. I know wheel size is a problem.
ps2. I once suggested a similar tyre compared with two different wheel widths. You said it would be good. I hope you will have a chance to do that one day. My own experience suggest that going for an inch wider makes the tyre feel like more stiffer tyre wall - but is it just my logical expectation. Im not good enough drive to be absolute sure.
Porsche drivers highly appreciate this video 🙂
Wow I’m so glad I found your Channel
This is great content, thanks. Very, very interesting to hear the ride quality/noise is not a big difference! I have a C2 992 and picked the large wheel size after much debate. I figured that the car had been optimized for the larger size since almost all models come with the 20/21 except the base. Now I might have to switch from the Goodyear Asymmetric 3 that came with the car to these new NA0 PS4Ss.
Hello dave! My dad has a 992 gt3!
Switch to the Goodyear Supersport instead.
Great job as always
Always go smaller: Less rolling resistance, Better ride comfort and traction, cheaper price... and the best part SIDEWALL, because hitting a pothole in 21" wheels with rubber bands for tires is more Spain without the S than a smaller wheel with more sidewall. You may want a larger wheel to fill the arches, but if its too narrow you lose traction (contact patch) If it's too wide, it interferes with the suspension articulation. For all thats holy dont buy wheel spacers to fit the wide 21"+ tires if your car never had that option before
I promise you, if you hit a pothole, the 21" are not the ones to go, it will be the 20" fronts. Ask me how I know.
Took part in the summer 2022 Nordschleife training offered by BMW and was really impressed by new seats in the M4 and the Pilot Sport 4S tires!
They work already at 40°C and the pressure stays relatively constant (2,2-2,5 barg). To be honest, you might be better off with the 4S for normal use (80% normal road, 20% track).
I have Cup2 on my car and the only difference is in the upper 5-10%, where you would not go anyway, because you risk too much.
Porsche + Michelin = Perfection. I have both summer (OE Latitude Sport 3's) and winter Michelin's (Pilot Alpin 5 SUV's) for my Macan GTS and am very happy with both setups.
It's quite the combination!
Ferrari + Pirelli = Delightfully Flawed? 😉 Maybe perfection is overrated. 🙂
Very interesting & great insight into hard driving, if only I had the talent to match my dreams.
Would love to see a review of the Bridgestone Potenza RE-71RS
Very interesting. So for normal street driving you like the bigger staggered tires now for cars like the BMW i4 M50? In wet weather/ in Snow? How 'bout when the tread is worn down by half? Any circumstances you'd recommend the 18's same width in the rear as the front? thanx. keep up the great work.
A video on a 4wd Vs a 2wd 911 dry/wet lap times would be great content.
Whoa.
So 20/21 is closer to PSC2 AND and 19/20 is more PS4S.
Seems almost like what BMW did to the m4 with the star tire, but with Porsche giving guidance.
Would love to see how these compare to a full on PSC2 set.
Awesome video! And your love of the PSAS4, is shared. Epic tire even almost 2 years in.
It does seem like a similar ethos to the bmw tire, just obviously tuned for the engine in the wrong place ;)
Great stuff, impressive indeed. 👏👍😀
What were the relative weights of the two sets, and what is the reason for a quicker laptime with the greater diameter rims?
Great video as always. Don't know what it is about your presentation but I find myself watching nearly every video regardless of relevance to me, just for enjoyment. To throw you a semi-relevant question to this video, have you done a comparison between different wheel/tyre widths in the same size before? I've got 19x8" wheels on my current daily with 225/45R19's, I'm about to fit 19x8.5" wheels and I'm trying to decide whether to stick with 225/45's or move up to a wider 255/40R19, which aside from the width is for all intensive purposes identical in every other dimension. Are there any obvious pro's or con's to either choice? Cheers!
Price differences can be irritating between sizes. Particularly if they have a low durability rating. I have a Boxster T coming with 20” wheels. The 19 tires are cheaper and have more bad weather options that are reasonable. I cannot imagine the cost of 21” winter performance tires. The other aspect is rarity of those winter tires after October. I have friends who get the wonderful Pirelli Sotto Zero line as i do. But they have huge wheels and if they pop a tire, it is often possible they need to buy a set of four as there are no in stock replacements. A set of new four from a different brand.
Rim size. If running winters mount them on smaller rims with a higher profile. B8t that's another issue
That's why you buy the smaller wheels for your winter tires.
Thats the compromise I had to make with my last car. I wanted to order it with the 21 inch wheels, however I opted for the 20 inch because the option of winter performance tyres. With my current car I now have 2 sets of wheels (summer/winter). 20 inch for the winter tyres and 21s for the summer performance. Not ideal but I want the best of both worlds without compromise. So I completely feel your irritation.
@@jasonleon1976 which winter performance tires did you go with?
Great video! Thanks a lot for all the information you are sharing with us.
Tho I really wish you could make comparison between a set of more narrow tires, such as 195 or even more narrow ones and say 225 ones :P
Is a 195 to 225 a bigger step (grip wise) then say 225 to 255 for a same car.
Looking at your other video, there was no much time difference between 225/255 combo and 255/285 combo, 1.28sec favoring wider tires. Would undersized 195/225 combo suffer same much timewise, or would it be even worse?
Excellent job! Very well done, interesting, informative, clear and useful, keep up there great work, I appreciate you!
I appreciate that comment, thanks :)
Jonathan, I need to buy winter tires soon and I'm waiting for your winter tire test video. When is it coming out?
Love your channel
Mid September!
@@tyrereviews Cheers
Hi Jonathan
Thanks for this special video: just great, informative, straight forward as always. Owning a 991.2 Porsche I wonder whether my car would profit from a different mix of tyres: front axle MPS 4S 245/35 20 NA0, rear axle MPS 4S 305/30 20 N0. Porsche certification is of course MPS 4S N0 in these sizes. AfaIk there is by now no size of NA0 in 305/30 20. Couldn't find any information about mixing (older) N0 specification with (new) NA0 specification. Maybe you could cover this theme in a test? Thanks and go on like that! 🙂
I'm happy with my 18s, assymetric 5
Great tyres
Brilliant as always Jonathan. What were the cold and hot tire pressures? Temps?
For all testing OE, though during dry handling we started at OE pretty warm
Great video! I just bought a 991.1 with 19" all around, date code from '23 and the tires are SO LOUD! Continental Extreme Contact Sport 02's. Recommendations??
I have PS 4 in my Tesla S P100D 21 inch staggered. It’s very comfortable and quiet with great handling! I was surprised how comfortable they are. I’m not pushing like you are though!
Hi Jon, great video as always, thank you! Quick question, why were the breaking tests 80/100 to 5 km/h instead of to 0 km/h? I know the comparison is still valid, just wondering what the reason is. Thanks!
There's too much variance in the last few mph from the ABS to get super reliable readings so we do it to 5. EVeryone does it, if they're showing 0mph they've calculated it from 5 or 8 kph
Thank you for the explanation!
I have an E92 335I on 18s and wondering if I should go for the 19/20 set up. Would you say it is worth doing or sticking to the 18s?
I’ve scaled down recently because I’ve began to prioritise comfort over looks.
Now I'm old I totally understand this
@@tyrereviews 35 is the new 80.
The first time my dad and I upgraded tyres was when we ha a Sentra 1991, we went from 175/70 R13 to 195/50 R14, years later we went all out to 205/45 R15, the looks was amazing and the drive in the canyons was outsdanding (for that time standards)
Nowadays we have a Mk6 GTI, a world of difference.
By going from a 175/70 R13 to a 195/50 R14 you also reduced the overall wheel diameter by 1". Therefor reducing the gear ratio but also making the speedometer indicate a higher speed than the truth :D
@@dufonrafal yes, I know, I use an app called tyreexpert to do the calculations so we wont get speeding tickets, the 175/70R13 to 195/50R14 change was almost decades ago, here in my country only now (like 5 years ago) is the speed being monitored,
@@jamdc2000 with the tire being smaller, if you kept the sane speed on the speedo, you should have been more worried of the traffic behind you honking at you :D
@@dufonrafal really Einstein??? ...and how much slower was my speed so the traffic behind started honking???
@@jamdc2000 let's take 55mph indicated with the original size, and assume that it's the true speed.
Well, with a 195/50 R14 instead of 175/70 R13, at 55mph indicated you would only be going 53mph. Not a big difference, but still.
Great video dude, any heads up on the PS5S?
Any plans to review some Yokohama tyres? I'm keen to see something like A050 vs A052 vs AD09 please!
Is the 20/21” setup quicker due to:
- 10mm more tyre width ?
- more capable compound ?
- or really because of 1” more wheel size / less tyre wall ?
I would say the largest difference in the dry comes from compound
Was there a weight difference between the wheel and tire sizes?
I live in Buffalo NY, 9.5 months cold and snowy weather, the rest summer what would be the best all season or best tire to have? Oh and I drive about 700-800 miles a week lol... 2013 Toyota Camry SE...
You drove the base spec RWD car. Which tires do you think would work better on a 4 or turbo?
Is the atvange really the biger wheels, or ist it bigger width? Im am impressed becaus biger wheels menas slower in the straight, even so is the 20 21 faster.
Would by interesting with 19 20 and same tire size as 20 21
Tnx again for ur work
This is mind blowing. I thought the N stamps were all just marketing and weight related. Wild difference here
Please make a Video about the different tires developed for AMG / Porsche with MO1 NA NO and so on... about their differences and what it means for usage on other cars. Because I couldnt currently buy rear Michelin PS 4s tires with MO1 but only without any branding or Porsche branding.
Check out the video on the M3 * marked tyre, should give you some good info
Can you do a video on the effect of tyre age on grip/performance etc? Eg. Using new (or lightly used) old stock. New, vs 2 years, vs 5 years for example. I have always been told that after 5 years or so tyres should be replaced regardless of tread wear, would be interested how much of an effect it actually has
I look at how much crack it has, if I get heaps of hairline cracks all over sidewall then I replace. These hairline cracks are quite a lot around 6 years. Old tyres isn't only grip that the problem.
Interesting Video good job
It would be interesting to compare them with other registered brands by Porsche in NAO,,like Pz4, GoodYear SS
Certainly would, however that's very... political!
@@tyrereviews that’s a part of your job negotiating with people in Armani suit ;-)
You are a legend of the tyre reviews. How is it your voice breaks in the car. Is it just from shouting.
Hitting puberty finally
Crazy that 20/21 is now a normal sport car setup, where I'm still on 18/19
thank you! 👍
I'm looking to get some new all-season tyres for road use for my Tesla M3 Performance with 235/40 on 19" wheels. Do you currently have a recomendation, or is there a review incomming? Many thanks.
Last years UHP as test is still a good go-to, so the Michelin, Conti and Goodyear are all good, but the Michelin has the edge
Good subject dude !
What about the impact of unsprung weight? I drove (admittedly 997's), back to back on the road and the optional 19's at the time made the car feel much heavier and more cumbersome than the same car on 18" wheels and tyres. It was an appreciable difference, not just placebo - is this dialled-out in the admittedly much newer 992's?
Modern wheels and tyres are incredibly close, I'll dig out the weights. In the 17/18/19 inch test i did on the golf the 18"s were the heaviest!
hey may i know, when are you guys planning to test the Yokohama AD09?
Can you please test the Michelin Ev against the pilot sport 4s please?
Love the video comparison 👌. I watched you 17, 18, 19 inch wheel video, very informative. Could you do a comparison again with the same sizes but this time change the overall diameter of the wheel. Would like to know your take on how it affects the performance of the vehicle.
I'll put it on the list
Do you need snow chains if you have winter tyres? Do you need them for 3PMSF all season tyres?
What a dream, hammering and smoking Michelins on a 911 on track. What is not to like? 😁🤩
Did you test the original Pirelli PZero some cars come equiped with?
I supose these Michelin are much better.
Thank you!
I've not yet no
German Sport Auto magazine were a bit critical to the Pirelli P-Zero NA0 compound. They said it's way more better in the wet than the P-Zero N1, but has a smaller temperature window in the dry. That's why the 992 Turbo S isn't faster on the Nordschleife in the Sport Auto Supertest than the 991.2 Turbo S.
As someone who tracks a 992 C2S, I'm a but unhappy about that. There are no Cup 2 available in the Carrera tire size.
My car comes with a 16 inch alloy 6j size with 205/55 tyre, can i put 225/50 on the same 6” alloy? Will it cause issues? I guess 225 is the max size to put on 6” alloy! Will it be a forcefull push to the car and ruin dynamics?
Hello sir,
Please make video on Wheel size and their respective fitment
Like whats the most reliable tyre size for 10j,9j,8j,7j wheel and what are the effect of using Stretched fitment.
For those tests check FitmentIndustries here in YT.
FT are great, and it is on my list to test
Hmm, wider tires, more traction. Makes sense ;-) !
Just for the sake of it I'd love to see you test/showcase the performance old no-name tyres vs a fresh set of proper tyres. Maybe find a neglected car off ebay, test some metrics & then treat it to new rubber to show the difference? Not just performance metrics but safety ones too.
I've half shot something similar to this :)
They are different tyres, different compounds, different widths. So how can you compare wheel size?
I think that Porsche and Michelin need to have somebody do some long term, summer and winter, performance/treadwear evaluations of these tires on their 911 GT3😉, any volunteers?
:D
I went from 19 to 20 so really interested in this
Do i sit slightly higher with 19" inch tyres or is it the same when i buy 18" inch?
Is a 17 inch tire better or 19 inch? For overall comfort and normal day to day driving
How much of this is due to width vs diameter. On my c7z06 I'm going from 20x12 and 19x11 to 18x12 rear and 18x11 front. On 20s and 19s I run nankangs cr-s and 18s Falken rt660 and yok a052
The compounding difference will be the biggest difference in the dry for sure, width can help but not as much as people think
I was wondering if you have any views on the tyres against the Cup2. I currently run these on a 718 Spyder and was considering the 4s’s.
I've a video covering exactly that, it's quite an old one
@@tyrereviews I appreciate that but I thought the new tyres were a different compound.
Interesting. I would think the smaller diameter would have performed better. Did you weigh each wheel/tire combo? As a few have said, if you're just driving on public roads, the 19/20 is probably the better choice for ride quality and slightly lower cost.
I'll dig out the weights, it was very close
On the street, they do. On the track (perfect road surface), bigger ones have larger contact patch, so they perform better.
Great video as usual . Did you notice any difference on 0-60mph?
Smaller wheels should give better acceleration and braking force.
Overall OD is very similar and 0-60 testing is very difficult to do accurately so I didn't test it :)
With Porsches I've often wondered if the base spec model is really the one to have, like less is more in Porkerland. Was there a big difference in unsprung weight because of the smaller wheel combinations? I once lost 18 kgs (unsprung!) by going 17 inch from 18's on a Cayman 987.2 and the difference in feel and handling was shocking.
I'll double check the weights
The base models are almost always the ones to have.
Cool, diffrent size front rare.. removes some understeer(in theory)..
hi can you do a test on the same tyre but different rim width (eg min and recommended) - say 255 35 19 on 8.5" and 9" rims, 235 45 17 on 7.5" and 8" rims for example
To throw a spanner in the works, is it the thinner sidewall on the 20/21 that gives better grip or the actual wheel size?
Mostly the compound in the larger size
The 992 is amazing and my manual 2S is incredible good and connected, I can’t wait to replace the non Michelin one by 4S. On S version you are forced to ride on 20/21. Maybe for winter you can switch on 19/20
It's good to be you
Hello Jon,
I'm wondering if anyone else have an interest in the tyre pressure!
Can you please, add some information in your future reviews about start/finish tyre pressure, temperature...track, ambient?
Nothing fancy, just 5-10 seconds in total for this information.
Thank you!
Cristian
Great content 👍🏻I'd like to s share that N spec PS4S really are different kind of animal. As I have the N0 version on my BMW for some time now, I can simply tell they are so much better not just compared to standard PS4S, but also the Ferrari spec K1 I've tried before. Have no clue how they made it, but the tyres have sharper handling, better grip, better wet feedback and at the same time they are comfier and have better rim protection. The only negative they are just a bit noiser. If the (very restricted) N spec sizes fit your car, I definitely recommend going buying them instead of other variants (especially the Ferrari that was pretty awful in the wet).
I've a video on the * marked G80 M3 tyre and you're right, it's nuts!
@@tyrereviews so is the * marked PS4S better or the NO marked PS4S ?
@@vollcare4076 the * marked will be better for bmws and the NA0 will be better for 911s!
Thanks
Chances are these tyres will be impossible to find here in Au (even if you could afford them).
It’s great that these tires are the same regardless of size on the Porsche. But I don’t have a Porsche… I feel like it would’ve made more sense to not use tires that are designed to minimize the difference.
There's a video on the channel covering it linked in description
Tires are the best mods you can do. I put the Indy 500 on my car and I went from 4.74 0-60 down to 3.99.
I wondered how is the PS5S compares to the PS4S in those sizes.
