Sneak Peek: Tire Physics Development

Wondering if any devs could possibly chime in on these topics:

With the tires themselves going through a big overhaul, will there be a large change to the way tires are selected/types of tires? And will their intended uses or stats (like optimum temps or pressures) be more readily apparent for users? Say there’s a rally stage, and we have a combination of asphalt, gravel and dirt, what level of tire depth are we looking at? Will it be simply: just pick the rally tire or will more unique surfaces and ambient temps play a bigger role?

in relation to this, will we ever get a better wheel selector too, the browser is a very neat thing but its still hunderds of wheels

IR temperature pistol, zip ties, go pro, strap to strut or suspension links to get real time disc temps? Of course this is presuming that track day enthusiast has removed those shields from backside of the discs to get proper cooling air flow.

For me at least tire sound improvements are something I hope to come from this research, currently it is bit hit or miss, I can be sliding at 20% slip angle without audible feedback, which together without G-forces makes experience slightly less than what actual physics can provide. However going to DD wheel most certainly has compensated lack of audio feedback as with a toy wheel speed of FFB just was not there. With DD wheel judging limits of the grip is much easier to me at least.

Currently some stiffer suspensions and lower profile tires tend to have something I call flat spots in FFB, maybe that is realistic, but when I'm driving Scintilla for example, feeling of understeer vs neutral is quite subtle compared to Bolide for example, together without much audible feedback it often leads me to plow straight to the guardrails. Generally with older vehicles that has softer suspension and taller profile tires, I find it much easier to judge between understeer and neutral. Oversteer is much easier to tell apart, imho.

Not sure if research will result improvements to those areas, but of course I am hopeful.

Regarding ABS, currently if you are too fast to go from throttle to brake it tends to get into some bugged out state, similarly with traction control that will forget to check if there is change to conditions if you dance with pedals enough when little wheelspin. While there can be issues with ABS IRL, these issues in BeamNG currently don't behave similar to real world ABS and TC issues, but feel more like if code just jams to some loop, but that is not much related to tire model I guess, however I might not be the person who knows much of this stuff, still it will be interesting to see if improvements to tire model can lead to need to improve some aspects of how electronic driver aids behave.

Data from higher slip angles is difficult to get as temperature increase changes everything with the tire, do you deal with this by measuring how much change there is with heated up tire and then doing math or just try to be quick and fill tire with LN2? It always puzzles me, do tire models include friction changes from temp as well and then temperature effects on top of that or how on earth it would be possible to get high slip angle data without temperature effects already there, it must be very difficult to achieve temperature neutral data.

Agree about alot of it. About the sense or lack of tire grip limit, which i absolutely agree with is hard to feel/know since we dont have as much to communicate that with as irl. I do one important (for me) thing in vanilla beamng, i always increase the g-force coefficient from the max of 20 (0.2) for a wheel to 80-100% (0.8-1.0) which can only be done in the wheels inputmaps file in your settings folder for beamng. I did make a mod that increased it but its not updated and this is so easy anyways.

I did release a mod where i tried to get this feeling better communicated through the wheel; i tried to scale part of the ffb forces using the g-forces (since i dont know if theres a tire grip value somewhere), so that the higher the lateral g-force (sensors.x?) the stronger the ffb would get. A very static way of trying to tell the user the tire grip since the g-forces is a dynamic thing, never got it good enough imo.

Kindly asking if there any news or progress to share ?

Sure Progress is still ongoing normally, so far we haven't stumbled upon any big blockers. The work on the necessary tools is ongoing. The research of the gigabytes of data in order to define the best approach for thermal physics continues at a reasonable pace (considering we cannot have some dedicated developer working on this alone 24/7; remember our dev team is limited, and the scope of our simulator caters to a lot more variety of users than people think).

So for now nothing exciting to share, just more dilligent work going on behind the curtains. No fancy screenshots or videos, and definitely nothing playable that can be released in updates any time soon.

Ever since the Release of the Video showing us that BeamNG is working on better Tire Physics, I have been obsessed with the Idea of it.

As much as I would love to see it in the BeamNG already, can we get a Video on the Subject regardless of its current State of Development? Maybe a dip into it in an upcoming Devblog?
