I recently changed my bike tires from 42 to 32 mm Continental ride city extra puncture tires. I had a very nasty fall on the wet concerte.. I can say I did not expect that since I thought they have enough grip. I did a very small turn and the rear wheel simply slipped. I am thinking to going back to a wider tire. Thank you for the video!
My current ride is on it's 3rd set of tires. I own 2 road & a touring style bikes. All have or had Continental or Pirelli tires. You give good information, I'll agree with a couple of suggestions. 1- The idiot or inconsiderate behind the wheel of the car behind you, 2- How cheap you pay for what looks like a decent tire. I used to ride to work (rain or shine) 5 days a week, even in winter weather (not always snow). Premium tires rolled great (90 - 100 psi), I'm now retired so this time I went towards cheaper cost on my grocery getter, which always had 28mm tires. The bike feels like the brakes are stuck on (80 psi)! My belief is the quality of the rubber compound & tread design (& tube brand) effects rolling resistance also. This based on my experience.
Hi you made very good points, quality rubber tires will ride better and will be more comfortable. I agree lower psi make ride sluggish. I always recommend to inflate the tires to the max psi value for optimum ride experience. Its good that you experience bike commuting, kudos to you 👍 Thanks for watching and suggestions. Cheers
I started out using 700x28mm SMPs and upsized to 35mm. For my 42 mi rt daily it only slowed me 4 minutes. Much more comfortable. Still ran them at 100 psi.
That's great and exact reason why I switched. I enjoy my rides with them with so much more comfort. Glad you are enjoying your long rides with 35mm tires. Thanks for watching.
Using 100psi in 35" Is very interesting... Curious what is the recommended psi range for 35"; what does tire show on side wall? How long have you been using 35?"...
@@Thankful_n_Gratefulmost would fall in the range of 55-75 psi on 35mm tyres, because you are supposed to run wider tyres at lower pressures. 100psi on 35mm tyres seems pretty absurd to me
I run 53mm tires on my main bike, ha. I thought about getting these, but once in the big sizes, they're just so heavy. All for puncture resistance. I haven't had a puncture on any tire in like 15 years. I don't get the puncture resistance obsession everyone has. I want comfort, low rolling resistance, and mileage.
Clint you made a very good point, I wanted to mention this in the video not to go over 34mm. These would be okay only substitute for 28 to 34mm anything above that would be quiet heavy because of the compound used in them. Thanks for watching and your input.
which means that the sidewall of the narrower tyre has to deform more, hence the higher rolling resistance (at the same pressure). Wider tyre could in theory add more aerodynamic drag, though, and also more weight. So what is faster/more efficient depends on both your speed and how rough the road surfaces are.
@@lunam7249 I'm old enough to have ridden 18mm... then 21, 23, and now 25. 25 is definitely not notriceably slower (for a given effort), but much, much less annoying. Which one is faster for a given effort depends entirely on the surface and on the speeds (because rolling resistance becomes less and less important in regards to aerodynamics, the faster you get, and wide tyres may be at a disadvantage here). Also keep in mind that there is another variable other than width: pressure. With equal pressure, the wider tyre will roll better, because the contact patch, with equal area, is shorter (requiring less sidewall deflection). In reality you will run the wider tyre at lower pressures, which can counteract this effect. In the real world, besides the "internal" friction of the tyre and the friction between tyre and road, you also have to take suspension losses into account. And these can make a "slower" tyre with a higher rolling resistance in the lab faster in the real world. So we introduce the next variable, the road surface. If your're cruising around at moderate to low efforts, then the wider tyre at a lower pressure is probably faster. Because what use is your slightly lower rolling resistance in the lab, when you are bouncing all over the place? On rough roads, suspension losses become so much more important than friction. Now on a velodrome with perfectly smooth surface, then the narrower tyre at absurdly high pressures will certainly be faster. If it were so easy that one tyre would be best in all situations and circumstances...
I have used these tires on gravel and they perform good, but i think they really shine on road as they absorb imperfections of road very well. So far they have not shown any wear tear as my rides are some gravel but mostly roads. For using these tires mostly on gravel I would recommend slightly wider version, (36mm or 40mm) Narrow or thinner tires from any make or model will slip especially when turning. Hope that helps. Thanks for watching.

I own road bikes and unfortunately they only accept up to 28mm tires. I use Conti Gator Skins. They are ok, except they don't repel goathead thorns and caliper brakes only are wide enough to accept 28 mm tires with existing rims. I would like to move to 32 mm or wider but would have to buy all new bikes. Alas.
Hi Stephanie, Gator skin will give you great puncture protection, but your ride will be a bit hard compare to traditional road tires. Frankly these 32mm Continental tires give me the most comfortable ride but are not fast. So in your case you can put these Continental tires in 28mm. This way you get comfortable ride, puncture protection and will be able to keep your current bike. Hope that helps. Thanks for watching.
These tires have much high gripping ability due to the compound they are made with so riding in rain and soft snow is possible. No tire would be safe in frozen icy road (black ice or sleet) where even cars skid. Hope this helps.

35 mm Grand Prix Urban is a very fast big tire too. I ride the GP 5000 tl in 32 mm and its like ridin on clouds....
Very true, I felt the same way about 32mm its much more comfortable compare to my 28mm on my Canyon Road Bike. Thanks for the comment.

The size of contact is the same. A narrow tire is long and narrow contact, a wide tire is short but wider.
Indeed
incorrect...air psi...your wieght in pounds / psi = area

@@turboseize its so obvious, the narrow tire has less resistance, ride a 700x 20mm wide at 120psi, then a big fat balloon tires....narrow is faster

Why would you not use tires on gravel path?
Grip, Wear out sooner?

You need 4inches width to hydroplane
Exactly. It's effectively impossible to hydroplane with a bike. I still can be slippery, though.
Is it truly 4 season? What about snow/slush/ice?
These tires have much high gripping ability due to the compound they are made with so riding in rain and soft snow is possible. No tire would be safe in frozen icy road (black ice or sleet) where even cars skid. Hope this helps.
What was your rim width???
It is 23mm.
