HTML-код
- Опубликовано: 7 май 2019
- High speed driving with high center of gravity vehicles requires adapting your standard driving style to suit the strengths and weaknesses of a high CG platform. In this video, we look at how to quickly determine the CG of any vehicle, how to operate high CG vehicles accordingly, and how to save a rollover situation should it occur.

Drive on 2 wheels video!! Always great content

Totally. Ever seen that video of those arabs changing all flying wheels while 2 wheeling? Hands down the most hilarious automotive footage out there.
@@Flyingdutchy33 nascar should do that
@@jibcano1777 No.
@@jibcano1777 now im imagining lemans prototype racers on two wheels
How do you drive fast with a high center of gravity?
Carefully.
Replacing the wheels with wider offset wheels with wider tyres as well makes an enormous differnce as well. All my vehicles have been high center of gravity because of where I live. They are a must. I have never lost control of one.
Indrid Cold - so for example , I have a 2016 Ram 1500, with a 4 inch lift . So going wider, like a 12 side tire for example ( I have a 33 inch 10 wide ) that would be better grip wise ? Or control wise
@@tudobem321 Yes. It would make a difference indeed. But do not stop at just a wider tyre. Get rims with a wider offset as well. You will not believe the difference. I have a vintage Jeep I lifted 4.5 inches and put 33x10.5R15 inch tyres on it. It seemed very topsy-turvy. I would take off on a turn quickly to lift a front wheel on purpose to scare people. But the rocking around and swaying started annoying me. I got rims with two and a half inches of offset and used 33x12.5R15 tyres that were not as good as the 33x10.5R15 to see what would happen. With older tyres and a worse kind of tyre, the Jeep ran super smooth, never lifted a wheel, and cornered way better. The swaying and rocking was almost entirely gone. I liked it so much that I gave the used tyres to someone else with a Jeep and rushed out to buy a good brand set of 33x12.5R15 tyres. Definitly buy wider tyres and rims with a deeper dish. You will not believe the differnce. I miss scaring the people in the neighbourhood by lifting a wheel intensionally. But it is far worth it. It will give better grip and control, by far.
Indrid Cold dude you , along with my boss have pretty much just answered pretty much the biggest question to my truck life haha .
Shoot you need to be my adviser at this rate before I pick a new rim and tire set 😂😂hahahaha but thanks man that helps. Cause it definitely sways to easy. Topsy turvy and all that. You just wrote my entire mental complaint . I’m
Gonna do this eventually when I can . Never thought a deeper dish would help but I’ll consider it
@@tudobem321 If not ready to buy the rims because of the price, get hub centric wheel spacers. They haved a lip that locks to the hub and to the wheel. This keeps it from having any off center motion and breaking lug nuts. The rims you have now will be spaced out two and a half inches, or whatever spacer thickness you choose. Amazon sales them very affordably. They will make your pickup truck handle as if you got the wider offset (deeper dish) rims without the expense you may not be ready to put out. With the spacers, you can also put the wider tyres on the rims without rubbing at full turn. Offset rims are the best option by far. But rims are expensive. Get the spacers, for now, and you will not believe the difference, even with your current tyres. Later get BF Goodrich All Terrain or BF Goodrich Mud Terrain Tyres. They have very strong sidewalls. As for the rim diameter, that would be your preference. But the bigger the rim, the heavier it will be and the less tyre you will have. This will make for a rougher ride. The ridiculous 22 inch rims with a one inch tyre will make for a very, very, rough ride, with possible damage to the rim on very slight bumbs with great ease. The small rim with enormous tyres will give a better ride with more traction but the sidewall flex will give bad cornering, the topsy-turvy feel all over again, and can be dangerous if you blow out a tyre and the tall tyre suddenlu does not support that end of the vehicle. Something in between the dubs with a one inch tyre and the tiny rim with huge tyres is what you need.
Want to feel old? The Firestone Ford thing was actually 19 years ago
Still having one of these tires as a spare tire in our 2001 Ford Explorer
Wow yup that's amazing
Hazgebu My 2000 Ford Explorer has Firestone tires. They were great. :)
Hazgebu I think it was more like 25 years ago. The 1st gen Explorer was the one with higher rollover risks.
Now Ford’s seatbelts start fires. So there is that. Leave it to an engineer to figure out how to start fires with a seatbelt.
3:35 starts a pendulum turn, then remembers it's not a Fiesta.
This is relevant to me rallycrossing my tacoma
This looks fun. Maybe I should bring my Raptor here
Bring chrisfix too.
last week i was at a rally in morocco, with my Lada Niva,
We were cruising at 80km/h in a gravel/dust road, suddenly entered a town and had to reduce to the limit of 30km/h.
My copilot scared me and I suddenly brake, my rear wheels started to go to the front and we went 2 wheel in the air.
got mindblocked and couldnt react countersteering, we hold our breath and then the vehicle went down the side of the road.
My right rear tyre got flat, sand entered the rim, we just had to inflate it and good to go.
won't happen again, learnt the limits of my Niva xD.
great video!
That is a nice Toyota Hi-Lux 4 door. You don't see to many 👍
Ya, ISIS cornered the market on the hilux
@@450ktm520 As soon as they're gone, I'm going to Iraq to pick one of their technicals up for cheap!
There's a lot in Australia and would imagine South Africa too. Just in Aus they really hold their value
they are all over the place in new zealand too
I'm not convinced that thats a diesel. I think it's a 4 door Tacoma with a bed bar that say HILUX
Pretty straight forward. I daily drive a lifted Cherokee and I've put it up on two wheels twice. Once on accident, and once on purpose. It's more difficult to handle but if know what your doing it can still go faster than most people are willing to in a low car on curvy roads.
can relate...I rallycross mine and its not very easy but its fun
As someone with a JL Jeep wrangler, I agree. I haven't gotten it onto two wheels yet, but I've cornered at speeds I didn't think the car could ever come close to, and I've slid it around quite a bit too. Just don't be overconfident,
The amount of difference sidewall, center of gravity and suspension stiffness can make is unbelieveable.
I had an outside tire pop on my car mid drift at ~50mph. Because it’s an independent rear suspension car with stiff coilovers (low power lol) and the tires were 45 profile, I barely felt it and correcting for it was really easy.
I wouldn’t even want to imagine what would happen in a Jeep or a lifted pickup truck with that high and soft suspension and 65 profile tires, even at 30-40mph.
Surprisingly, I've found higher profile tires to be much more forgiving (I haven't popped a bead or burped yet). But that's my experience. Rally crossing a Cherokee for me is like they've covered here, 90% is about setup into the corner. You can really make it look graceful and slow but be traveling really fast through corners for having such a high COG. It's not stage car fast but impressive given the weight you're sliding around (really scares spectators sometimes lol). You can really feel the weight shift around and I feel it's made me a better driver on pavement because the weight transfer skills really transfer well.
I don't do fast driving in my jeep, just slow crawling. But I hit a turn at about 35 mph and my enormous mud tire started barking. Scared me to death and I felt it want to roll
@@General_Eisenhower1945it is a completely different setup than anything intended to rally, big high flotation mud tires will certainly add to your rollover potential and they're far more dynamic than a lower profile tire.
I was in Colorado in my grandfathers (very wide) bronco when I was like 11 and he had a massive 100+ acre field in front of his cabin. He wanted to mess around a bit so we went out into the field to just shred about, all the grass was super low but we slid it at about 50 and there was a hole and when the tire fell in and hit the side of the hole it ringed the whole tire and debeaded it like a machine, it was scary feeling the car drop but it dug in so fast and stopped us that it wasn’t really an issue. I believe after that happened all he did was a wheel replacement because it was totally fucked because everything else was perfectly fine, the tire and the rim took everything.
Edit: I wish I remembered more about the bronco, it got totaled a few years ago by a drunk driver. I do remember it wasn’t registered and probably wasn’t street legal.
You guys have an awesome collection of cars and trucks there.
Do a 'How to J-turn in a high CG vehicle' video.
I'd like to see a 2 wheel video, I used to rallycross a 2WD Jeep Cherokee, and I can speak from my own experience that with a higher COG, it's very important to be aware of changing ground conditions. Just as you alluded to, As people continue to run a stage, particularly on very wet loose courses, the ground will tend to pile up and dry out toward the outside of a corner, meaning you're going to be changing the coefficient of friction and drastically increasing your rollover risk due to the higher soil mounding (and hardening) towards where you previously were skating around.
My experience, correct me if I'm wrong but this has always worked for me, I've been lucky enough to still have enough steering to snap it back over on all 4 wheels, but throttle wouldn't do much because I ran open diff. The key in that sort of situation when you're RWD open, is to not overreact, and deliberately deliver enough input to pull the vehicle back without causing it to roll back over the other way around. Once on the ground deliver a good gust of throttle if possible to help stabilize the vehicle and take up some of slop in your suspension and power out (if at all possible - if this happens in a chicane, you're possibly looking at a different technique).
The clips are looking so good with all the drifting and off roading
I love that someone bothered to import a hilux even though the next generation was available as a 4 door. That just makes me happy. Also 2 wheel video... definitely should do that
Saw Team O'Neil with a picture of my truck on it, immediately clicked! Most of these points are pretty self-evident, but the tip about slick surfaces making you less prone to rollover was something I didn't know.
Friend three wheeled his dually crossing over a gravel road where someone plowed their driveway across the main road... though my mirror was touching the ground at one point! Great recovery!
Great video, I learned so much, like the fact that more grip increases the risk of rollover. I would never have guessed that.
Thanks for all the cool videos!
Thanks for watching!
been wanting one of these videos for a while!
Really fun video to watch, you often forget how much give tires can have until you put your summer tires back on and remember how much stiffer the car is with a smaller side wall and harder rubber
Please do a video about driving on two wheels. Love the channel!
Waited all week for a moment to watch this; well worth it! Downhill & gas!
2 wheels would be awesome Ala James Bond style!!
Good info to use, thanks 👍
As someone who hoons in a R(ally)av4, great tips and information!
I love rally cars, but I just got a 2002 4Runner. So, this was hugely helpful.
Also, make a driving on two wheels video!
On 2 yes! Another great video! Thanks
Just do it, I'm sure we all want you to teach us how to ride on 2 wheels, cause it's so useful ;)
So so relevant to daily driving right?
@@Teamoneilrally yeah, I mean it's easier to fit into tight spaces that way :)
@@piciu256 Narrow alleyways and such, yup we'll use that haha
Owning an old SUV I get scared when I suddenly need to bank a turn, now this feels like a safety tip, thank you for the tips!
Love your videos
Yes!! This video is the best. I drive a XJ 3 1/2" decently fast in wv and trust me. Wheel spacers and experience is the only thing I can suggest to get thru our hollers.
You have to do the two wheels driving one! You guys are amazing, if I didn't live an ocean away and a day behind, I would love to come and get some lessons. Maybe one day I will anyway.
Recovered a Maxxpro from rolling over once. Learned a whole lot about setting the suspension up for the turn before cranking on it.
The Navistar International MaxxPro is quite prone to rollovers compared to something like the Oshkosh M-ATV.
Speaking of which, I actually have a bit of high-speed experience on the Oshkosh M-ATV. It's a fun class I MRAP but suffers from bad visibility and low space for both occupants and cargo.
AWDfreak It was my first time driving a maxxpro the mat-v’s were fun to drive, though.
You guys are awesome
That's some really good Jeep XJ footage. Mm!
Haha, I'd absolutely love to see a drive on two wheels video
My Sierra on 12.5” wide tires and upgraded sway bars corners like a Camaro. Well not quite, but it blows people away when they ride with me.
I got a ride in that Hilux once! It is quite an epic vehicle.
5:30 just do it
I've found a lot of the time vehicles with high center of gravity will have large side wall height and the tires will totally flop over in a turn. It's really sketchy. I drove a 2005 Silverado with a G80 in the back in the winters here. It was crazy fun and the angle I could get with it was insane. Good times. Haven't rolled anything yet, but totaled a Honda pretty good once!
more of this please! also 2 wheels would be neato.
We definitely need a drive on two wheels video! That would be dope haha
All my vehicles have had high centers of gravity. Where I reside, a regular car is only able to be used about five months out of the year. Those that have a bit more money than I have I'll have a sport sedan or a coupe for about five months out of the year and a true 4x4 for the other seven months. I just drive my armageddon mobile year round because I do not have as much money as the other families that have two, or more, adults working. It is just me by myself. My armageddon-mobile has served me very well since 1996. We started our life together in late 1997. She only had 11 miles back then. She now has 401,000 miles and still running strong. The trick is learn everything you can about your vehicle yourself and do all repairs, upgrades, modifications, and maintance yourself. You car might just last you a lifetime.
Ask my g/f, only one I know that drifts her Honda pilot and wonders why the transmission is fried.
Yea don't let her buy automatics then.
interesting video. Please do driving on 2 wheels video
Good, I'm gonna try what I learned on a Suzuki Wagon-R
I always wait till the end and watch the ending commercial.
Was hoping you'd get it up on 2 wheels and save it!
I took a 01 gmc jimmy into a corner at like 100mph on pavement took it to its limit and it was the most fun ive had driving
Off road racers are excellent challenges to design and setup. The ideal off road racer has excellent ground clearance and wheel travel, yet somehow have a low center of gravity and a high rollover angle.
yeeees! want tutorial on driving on 2 wheels! id assume you mean left or right side not front or back? :)
I got a goood ol XJ, show us some high speed cornering :)
Very awesome video, Would be also nice to see in the future more tactical driving type things. Perhaps with armored SUV's and such
Great vid! I actually have the same truck as the Toyota.
ALPHAFERT _ What year range is that?
In for the 2 wheel vids
How to drive on 2 wheels would be an AMAZING video!!!
Weight help when on gravel when going fast. I can drive a 3/4 ton or 1 ton much faster on my logging roads than a 1/2 ton. I do about 60mph in the half ton and can easily maintain 75mph in the heavier trucks.
Could you do a more detailed video? I run sweep for rally’s... my truck feels perfectly stable when it’s sideways tho it just feels slower
2 wheel video please 🔥
Two wheel driving please. No really, please, do this. Comment, more comments!!!
Did you ever make the driving on 2 wheels video? That sounds like an awesome video
This Hilux is aJewel. Really hard to find one like this. And if you’re lucky enough it cost a lot of money. I had a Xtra Cab one with 3.0 V6 and it was an awesome truck. Now driving a Pajero 3 👍🏻
Please do a video on driving on two wheels
My suv sf5 forester would roll a lot with grippy tyres but it would never roll over. I just had to wait to get all the wait on the outside tires and out corner a little hatchback on the roundabout🤣 Now with stiff coilovers no more wait just insta max grip of the tires. It it will not out turn my much lighter zzw30 MR2 thou once it has the actually grippy tires😁
Can you possibly do a video on handling large/heavy vehicles that don't necessarily have a high roll-over risk? Something like a Vic?
I, personally don't have an issue with handling said weight, but I've met a lot of people just cannot fathom handling more than a ton and a half in corners.
They do have a vic. That would be a great video
Would love to intoduce others to the wonderful world of Vics.
@@towcat never driven one myself, but i bet they are fun to mess around with.
don't let media or games fool you about their speed. They are by no means fast (by sports car standards), but they are swift and they accelerate very easily if you're just cruising. When thrashing, though, the Modular just falls flat on it's face at high revs. I'm sure with less weight, this could be a fantastic base engine (and it sounds *amazing*), though.
But I've met so many people who just cannot fathom how someone can manage such weight in a boaty car like that when driving fast and around corners. I cannot explain it well, hopefully these guys can.
Hi, I have a question about what you said about the 2wd/4wd.
You didn't talk about that a during a slide a spinning wheel would push the gravel to the side, and locked wheel would catch the gravel and cause a roll over.
In 2wd it's much easier to smash the throttle and don't worry about it, and in 4wd it's not. So actually on fast trail driving you better of driving 2wd
You're punching the throttle into your corners!?
@@cgunugc nope. Most roll over occur around the Apex anyway
Solid point, but you sound like you've got a lot of experience... When a newer driver smashes the throttle in 2WD, it can get really ugly really fast haha. For an advanced driver, 2wd and sliding you'll definitely stay planted better than 4WD and leaning, good call.
You should do a will it rally episode on that f450 dually
The utting the vehicle in awd is true but if your in a ATV there's a point where you will flip it no matter what u do so if you have something like a artic cat 300 where u can fully compress the suspension from jumping into it then u want to make sure it's innrwd if it has the option. And know how to not go crazy on the drift or u will flip
I get bored and slide around in my truck, just because its 18,000 lbs and 13 foot tall does not mean you can't have fun 😝
18,000 pounds!? Holy hell. Your average 3/4 ton pickup weighs around 7200 pounds. That dually at team O'Neill is probably around 8000 or so. What kind of truck do you have?
@@ianholmquist8492 Well the tandem axle dump truck I drive is about 26,000 lbs, so it's not that big. Maybe a single axle box truck?
Two wheels video please! This one was great.
Please do a video on how to drive on 2 wheels
Hey Wyatt, not sure how accurate is what you mentioned about RWD is more risky than AWD, I found the opposite is true, the bad way on a ATV, was doing donuts on RWD, then when I switched to AWD, it had a lot more grip and the ATV flipped over, happily I came out without a single scratch. In my opinion, RWD gives you less lateral grip, you'll get side ways before you roll over.
I'm thinking about a Nissan juke nismo rs AWD.
How stupid is the idea? And what problems do you think it has?
the problems I know is the garbage cvt transmission and the lack of a hand brake , but I'm thinking to convert the cvt into a 5 or 6 speed manual and I think that the handbrake problem could be solved as well.
Sooooo... How bad is the idea?
In all the years (and tires burnt through) drifting my '95 4x4 F-150, I never managed to tip it. I feel so unaccomplished!
2 wheel vlog please!
If you're confident enough and understand the physics of momentum you can easily whip a full size truck/SUV just like a mini Cooper in street traffic. I do it on a daily basis in my K2500 suburban because most people are more interested in their cell phones than driving with traffic flow.
two wheel drive video please
Driving fast is not good for 4WD set ups though
domosRAGE so much fun thought
Matt Drees if you like breaking things, then sure it's fun
@@domosrage5434 You have to be smart about it, know your cars limit. I love to rip down gravel/sand back roads. My car can handle it fine, the danger comes from driver error.
Driving fast on anything but a road is not advisable even on a vehicle built for speed and cornering. But a 4x4 is the worse for driving fast and making quick cornering. All I have ever had are true 4x4 vehicles and love playing with them at higher speeds when I am alone and lifting a wheel. I would never drive that way with a passenger, though.
do it!
2 wheels video, yeah!
Sweet so now I can drift in my truck
Send it!
You weren't drifting your truck already?
Go into a turn in four wheel drive mode. In the middle of the turn disengage the four wheel drive and go into two wheel drive. This will make for a fun ride. Make sure there are no obsicles near by, holes, or bumps. If you have a passenger, put down plastic bags on your seat and have an air sickness bag.
Please send it W!
Ok, I really want to see that driving on 2 wheels video 😂
In short: slide always, and if you hit a curb hold on!
As far as drifting my X-TERRA, I recall, full send. If you try to slide it, but doesn't fully go for it, the car tends to grip back and roll over, so step on that gas boy. LSD helps
Do the drive on two wheels video
For anyone interested in the more science specific side of center of gravity and rolling over: check today's video of Engineering Explained, he talks about safety ratings and the rollover index.
I've never driven my truck "fast" - which in my terms is anything above 80 MPH. A bit arbitrary, but hell if I'm throwing a 7000lb brick down a Wisconsin interstate with reckless abandon. Anyway, I always found it important to keep an eye out for areas you can drive to if you're unable to stop in time. Most of our highways are rural, and so there's usually a big grass median or hard berm on either shoulder. In the case you slip up from rain, snow, or just inattentiveness, getting your truck into the grass could save you and some other people's skins. Brakes are WAY better on trucks nowadays, but even then, physics says "impulse" and "momentum", and all I can do is throw my hands up and say "fuck it, I'm getting my truck grassy."
Good video as well, I should mention. I feel like the dingbats in their bro'd out Wranglers should see this video before weaving between lanes at 90.
I really like the content of your videos and they're really informative and accurate but the audios really bad on some of them, can't barely hear it.👂
Just a quick question what is the size of the tires on that Toyota Hillux 265/70 15r?
Just looked, the tires are labeled 31x10.5 r15 so the closest equivalent would be 265/75 r15. These are the Yokohama Geolandar i/T
Thanks for the answer her from Denmark
chill with the outro volume level lmao, scared me, 2 wheels video necessary
2 wheel driving video!
Does anyone know what kind of tires are on that Hilux?
Yokohama Geolandar i/t
To prevent a roll over when you’re sideways, gun it, sounds dumb but your tires are less likely to grab if they are spinning out, sounds dumb but it works
2 wheels video!
2 wheel video!!!
I may have heard Mr. Regular use Wyatt's accent before. I'm your dad!
How high is the roll over risk in a low to the ground rwd sports car such as a brz?
Very low risk.
@@Teamoneilrally That's a relief. Great videos btw!
