Broken tires and question about ABS

    How come the tire still has pressure?

    Also another question. That pickup has ABS, and ABS is supposed to let you steer even when braking heavily. However when I hit the brakes I cant steer at all in any direction, I will just hit the object I was trying to avoid.

    You have misunderstood what ABS does. It prevents a wheel from locking under heavy braking (by releasing the brakes actually :p). I think the D15 only has it on rear not the front so it wont aid steering at all, even if it was on the front it wouldnt help that much, usually the issue is that you are steering at full lock which counter intuitively will not make you steer when you are moving at speed (the wheel will just skid sideways instead).

    The tire - It is not actully implemented in the game. It is one of the games bugs. The mesh broke, or something along those lines of meshes. Tire inflation/deflation hasn't been added.
    ABS - I can't answer lol.

    There is partial support for inflation and deflation. JBeam has a pressure parameter for wheels, adjusting it does indeed cause the tyre to be softer or more rigid, setting it to 1 does seem to make the tyre go completely flat, 0 wouldnt load the Jbeam on the monster van.

    Just seems right now mesh damage doesn't adjust the tyre pressure.

    You can pop a tire and it will eventually shred. Haven't ever gotten one to shred but I saw it in a moonhawk wheely video thing.

    That tyre is popped. They do deflate after an impact, usually represented by the deformGroup breaking. The reason that rim isn't all the way on the ground is the other wheels are supporting the pickup's weight, but if you look at the tyre you will see that it is, in fact, flat. If you see this light on the dash, you have a flat tyre. The Moonhawk replaces it with the actual words "Flat tire" that light up on the dash IIRC.

    ABS should allow you to be able to steer because the wheels don't lock. That's one of the main reasons why ABS is used along with shorter braking distances.

    The abs on the d15 is only rear. That means it only keeps the rear wheels from locking up. That means the front wheels can still lock up, making you unable to steer.

    ABS doesnt help for cornering. If your braking in the corner you are doing something wrong. ABS can only prevent the wheel from locking under forward motion, it does nothing to stop a wheel from skidding because you've just turned the wheel to full lock while travelling too quickly.

    Then why did you say you can't steer when braking, steering = cornering.

    I thought that by braking in a corner you mean braking in a curve. and losing control because starting to slide sideways or something lol

    but if it was unclear what I was actually doing I did the following

    1) point nose at a tiny cube in the demo map, keep some distance
    2) accelerate straight towards it at 100kph
    3) getting sort of close, hit brakes
    4) start steering left to avoid collision
    5) "no" regards car
    6) watch as I slowly hit the cube I was trying to avoid

    thank you ABS

    You just don't get it do you? Pickup trucks don't turn on a dime, especially when the front wheels are locked up.

    It only has ABS on the rear wheels, as did most trucks from the late 80s/early 90s. As you might know, the rear wheels are not responsible for steering. Also, a tire can only use its grip to turn or brake, or some compromise of the two. You can't effectively brake and steer at the same time. Slam on brakes -> front wheels lock up -> steering does nothing. This is why you brake before turning ;)

    A 100km/h elk test in a road car while braking pretty much guarantees understeer or a violent fishtail -with or without ABS. It isn't a magic driving aid. All it does is reduce braking force such that it doesn't overcome the friction between the tyres and the road.

    I see your point that a rotating wheel would corner 'better' than one which is locked up, but high speeds with the steering at full lock? Its benefits would be negligible.

    Experiment with the Grand Marshal. That has ABS on all fours fo sho.

    Why did they do only rear wheel ABS?



    I just answered to that guy. I got it quite some time ago that the ABS is only on rear wheels







    steering at full lock? It takes time for the wheels to turn to full lock and the car is slowing down very rapidly as the wheels turn more. Not to mention I didn't start steering at 100km/h in my test, but a while after starting to brake. Did it solely for the purpose of testing maneuverability while braking with ABS before I knew that front wheels didn't even have it

    Cost. ABS = $$$. Now electronics are cheaper so ABS = less $$$
