Perfect formula. Balance between traction and power. Only the off-road driver knows it. Practice will make you perfect. Two full decades seen it all the time. Getting the right balance.
So many people need this video in their life! Everyone wants lockers before finguring out throttle control. There is many elements to it whether it be rocky terrain or clay hills and knowing what you need to do to maximize traction is key.
This is exactly the principles I learned quickly in my light Zook. Still trying to find that balance in the big weighing rigs. More 4WDers need to see and understand this video to cause less destruction on trails Perfect video example thanks Matt👌🏻
Hey Matt, love your video as usual. I think you nailed it when you said practice makes you better. It's like anything I suppose. I naturally worked out the right mix for getting my car through or up by just getting out there and doing tracks. I have a front e-locker going in soon to compliment my rear locker. I'm really looking forward to just getting out there and practicing with it so I can get even better.
Perfect. Very low gears will increase the traction a lot, but this is the technique I use with my standard jimny to tackle technical courses where a lot of big prepped monsters fail (most of the times way to heavy)
@@MadMatt4WD aint that the same? Less speed means Less bouncing means even pressure means more traction. Hence, the point Just before losing traction is were the most traction possible is. I dont have enough money to install a creepgear, so the momentumtechnique is where i'll be 😀
Hey. Yes you’re right. I think what I’m getting at is that for any given moment on a given surface the tyre has a certain amount of traction. This is constantly changing as the vehicle moves and the above changes. So if you stop, at that moment the tyre will have the same traction on the footprint regardless of if your stopped or doing 100kph. The only time this changes if there’s tyre slip. Does that make sense? So then we get to add the momentum to that and this is where crawler ratios come in because we can access the lower momentum zones which you refer too.
Brilliant explanation. 👏 One thing, which was not really emphasized is the potential for vehicle damage when too much momentum is used. To get to the point of wheelie or rollover, you would need to have put the suspension under a massive load and the wheels would be spinning in the air risking a CV failure upon landing as well. Mechanical, and track sympathy are key to sustainable off-roading. Here in South Africa there is a lot of focus on the environmental impact, so driving tracks as gently as possible is a requirement to stop trails being closed.
Also worth noting that traction depends on friction, and static coefficient of friction is always greater than dynamic coefficient of friction. Important therefore to use momentum to overcome an obstacle, but as you showed, don't then floor it. Keep the wheels turning at the same rate as the vehicle moves to maximise the traction to keep you moving as the momentum runs out. In the earlier example, by flooring it after getting up, you made it up but then the dynamic coefficient of friction along with bouncing wheels wasn't enough friction to hold the vehicle up and you started to slide back down. There are of course other examples where spinning can increase traction, such as wet rock where the heating rubber of the tyres actually helps to dry the rock and increases traction. Another example might be deep mud where the tyres gain more grip by flinging out the mud from the previous revolution, so a spinning tyre can work more effectively in this case.
Cheers Matt, I seem to just gun it everytime because I have a fear of gettng stuck halfway!! going to try and learn to slow down a bit and use more traction next time im out there.
i have been trying to explain that for ages in times where a track will have you lift a wheel slightly where you can just give the throttle a blip while all tyres have tractions and then as soon as the tyre is in the air let off and let it float over until you feel it touch down again then continue. (mostly in the sense of pre lockers but still relevant now that i have some)
I went sand dune driving for the first time a few days ago. Our guide took us to some obstacles which we had to hammer the truck through in the hope of getting over. In my opinion I was going way too fast to safely do it. My suggestion was to air down from 0.8bar to attempt to get more traction and lower the speeds (momentum), down to (let's say 0.5bar). All that he said is that I would roll the bead off and that I was wrong. Surely there is some merit in lowering speeds and increasing traction (to a point) and thus making things safer and damaging your vehicle less?
Look up running bearings in oil. I think i touch on it in there. Basically upgrade to 10mm studs if you have dramas. Lots of stuff on how to do that out there.
I used to be good at it, but a few years of hardly any seat time, combined with my favourite tyres being discontinued, means I often find myself struggling to find the right balance.
I've got it down pat Matt. Never try a track like that! In my minds eye, I could see the vehicle rolling end over end, and without a roll cage...not my cup of tea.
I only have LSD in the Patrol but I will never ever drive this sort of terrain you are .... I would certainly drive it in my Massey Ferguson 80hp tractor which I am sure will drive most of the tracks a 4wd vehicle struggles! LOL
Matt, a perfect explanation of “as slow as possible & as fast as necessary”. Cheers Non Stick Nick
That's an excellent way to put it.

Yep same.
An exceptional video on how to manage traction and momentum.
Cheers
You deserve more subscribers. Not many youtubers talk about traction and technique like this.
Thanks.

Yes Yes Yes
Not wanting to trash my jeep, I'm a firm believer in not to much momentum. Nice explanation of combining the two.
I’m the same
What a beautiful Bundera you got there. Fun sized off roading💪
Oh it’s a tops little 4wd. Goes hard too.
Excellent again Mr Mad...

Perfect video example thanks Matt👌🏻
Thanks mate. Share it around to help get the message out.
Very helpful information , thanks
Thanks
Great advice Matt.
Hope people put it to practice and protect the tracks and there 4x4s. Love your work. 👏👏👏
Cheers mate
This will help me a lot
I work on it every time i'm out. I'm sure you'll see the improvement as you practice.
Much needed skill to drive well and grow a drivers ability
Well said
Awesome Video! I enjoyed the extra examples of footage of the other vehicles.
Glad you enjoyed it! The shooter worked hard to get that :)
Great explanation
Thanks mate
Hey Matt, I'd never thought about it in those terms, but it makes a lot of sense....nice way of explaining it....
As nick below said. Go as slow as possible and as fast as necessary.
@@MadMatt4WD that was how i had previously heard it expressed.....

100% mate. I’m in lockdown atm and haven’t wheeled for months so I know I’ll be very rusty for the first few hours.
Thanks mate…. Great info
Glad to help

I don’t think it increases traction but it does increase control.

Very well explained definitely helpful I'm going to go out on a 4x4 session soon and that has helped nicely cheers matt

Looking good Sir!

Super helpful - thanks! And I want that rig!!
Nope. Not going to happen

this would have been the perfect opportunity to work together
For sure. Unfortunately this was filmed before we met. But hey there’s always next time.

Yes yes yes.
Thanks Matt. This is very helpful and informative. In your opinion, what is better for off-roading; automatic transmission or manual?
For technical stuff auto every day hands down. This vehicle is manual and I will be making it auto soon.
@@MadMatt4WD Thanks Matt. My '94 YJ is manual and there are times I bypass an obstacle because of that reason. Thanks.
Matt, your lessons are very helpful thanks. I love your demo's. Which locker is best to install first on a Triton with open diffs?
Go watch my video on front locker vs rear locker. Glad I’m helping you.
@@MadMatt4WD I saw it. So a front locker first I think.
That’s as a general rule.
I went sand dune driving for the first time a few days ago. Our guide took us to some obstacles which we had to hammer the truck through in the hope of getting over. In my opinion I was going way too fast to safely do it. My suggestion was to air down from 0.8bar to attempt to get more traction and lower the speeds (momentum), down to (let's say 0.5bar).
All that he said is that I would roll the bead off and that I was wrong.
Surely there is some merit in lowering speeds and increasing traction (to a point) and thus making things safer and damaging your vehicle less?
You’re absolutely on the money. Now of course you can roll the bead but you can drive around that to a certain degree.
Good stuff.
Have you upgraded the front and or rear diff studs. I have been having a leaking issue on the front of my 80.
This is not an 80 :) so it doesn't have studs on the rear. The front is all standard studs though.
@@MadMatt4WD Yes mate but you have 80s including your great race ute. I haven't seen anything on your channel about diff studs.
Look up running bearings in oil. I think i touch on it in there. Basically upgrade to 10mm studs if you have dramas. Lots of stuff on how to do that out there.
What do you think about "electronic throttle controller" are they worth getting?
None of my vehicles use them but from what I’ve heard a quality unit can be worth fitting.
I used to be good at it, but a few years of hardly any seat time, combined with my favourite tyres being discontinued, means I often find myself struggling to find the right balance.
Yeah I get rusty too. Even changing vehicles takes time to dial back in.
Mean landcruiser bro what size wheels bro
33x12.5-15"
You ever any problems with the tires coming off of the wheels at 12psi?
Yes I have. I really should run bead locks but they’re illegal for road use in Australia. I’m going to have to run slightly higher pressure.
@@MadMatt4WD why are beadlocks illegal? That is odd..
I'd also like to know why bead locks are illegal on the road. Not sure I could even guess why.
You tell me. We have muppets in charge of making road rules here.
Sure can understand that but you seem to be better off then us since its Muppet droppings that run this place right now.
Trying to show a fail...Oli's it anyway 🤣👍 It's hard to show that with a 40/75 chassis that dominates most obstacles.
Yeah I struggled hence the 60 series shots. It also goes so against how I drive.
I've got it down pat Matt. Never try a track like that! In my minds eye, I could see the vehicle rolling end over end, and without a roll cage...not my cup of tea.
I can’t settle for that. I love having a go. Rolls at these speeds don’t usually hurt
@@MadMatt4WD Yes, I can see that. So how many rolls does it take to hurt? :) Go for it Matt. I've become a scardy cat in my riper years.
"If ya don't Roll it , ya not tryen🤣" yes sometimes you do look at something and say "mmmmm think I'll be patient and let winch to do it's thing."
Lol. I just competed in a higher speed Offroad race. Loved it.
Ha ha for sure. I’m not personally worried about being in a rollover it’s more that I wreak my 4wd.
Treat the throttle like there's an egg between it and you foot...
Yes. I say squeeze it like a tennis ball.
I only have LSD in the Patrol but I will never ever drive this sort of terrain you are .... I would certainly drive it in my Massey Ferguson 80hp tractor which I am sure will drive most of the tracks a 4wd vehicle struggles! LOL
Lol. I’d be happy to bring a tractor but having driven a lot a massys I do t think it’ll keep up.
