Sneak Peek: Tire Physics Development

I second this. Some kind of tyre debugging tools would be great to have. Spreadsheets can only get you so far lol

Also extremely hyped for the deeper tyre simulation! I'm wondering, would it still be based on friction coefficients, but with a deeper simulation underneath?

 

Will the square tire have full tire thermals simulation ?

And by the way, the Beamng Team is absolutely incredible !

 

Yes, I understand that you don't want to increase the cost of calculating a more "polygonal" model, perhaps at speed the "square wheel" effect is reduced, but cars also have the property of going slow) in any case sooner or later you will have to significantly improve the tire geometry, and thanks again for your work!

 

Is there going to be tire WEAR too?

 

The video showed development in tire handling, physics, thermals and wear

 

Is there any loose surface improvements/testing you guys are doing too?

 

How about continuous track vehicles for the next step after that?

 

Beyond excited for the future of this game. And the amount of work y’all are putting in is truly commendable. In a world full of companies trying to make money the quickest way possible - companies that don’t care about the consumer - BeamNG really is special.

I started a thread a while back (that got no attention) about tire wear and thermals and how so many wanted it but implementing it accurately is insanely complex. I said y’all wouldn’t do it if you couldn’t do it right. The proof is right here. This tire testing process is complex, time consuming and surely expensive. But y’all are doing it and I couldn’t be more excited for the future of this sim.

 

Seeing this amount of work and dedication, and then remembering the game costs 30$ is insane. Awesome work being done, and thank you for sharing the behind the scene stuff, really cool to see!

 

I know this is still very early in development, but I have a couple of questions:

1. Will the tire and rim be able to be separated?

2. Will tire punctures/flat tires behave more realistically? I'm talking about the weird holes in tires when they pop.

3. Are there going to be more dynamic tire failures like tires losing air pressure depending on how severe the puncture is?

4. Are flat spots going to be a thing?

Overall, I'm extremely excited for the future for this sim. Only BeamNG would go out and collect real life tire data, collaborate with another company, and perform real world tests just for their new tire model instead of using insufficient data like every other game. This is why these are the best devs ever.

 

Just gonna say, i think games like iracing probably do this kinda testing or even more; i mean, even gran turismo got a partnership with michelin for this

 

Really glad we see progress in the tires subject! Personally, I'm really curious to see the dynamic differences between a standard sport tire and the Selecta SportPlus 2R one in more detail than just longitudinal/lateral acceleration and braking (plus I want this tire to be put in the Vivace Arsenic models because it's already available in the 245/35R19 size)!

Plus, I believe that this progress, when it arrives in BeamNG, should be celebrated with introducing names to the tire parts! We have the Selecta and GripAll tire brands, the Selecta SportPlus 2R tire, the GripAll racing/dragging slicks and the rest of them, from the humblest to the sportiest and from the lightest-duty to the heaviest-duty ones, are simply known as "GripAll AD82T". Some company and model differentiation/variety is, therefore, necessary!

 

The last blog post on tire physics was in 2021, 4 years ago.* If you don't want to be disappointed by waiting for an update that takes longer than expected, assume that we're at the midpoint of development and that new tire physics will be implemented in 2029, 4 years from now. There will be plenty of other exciting stuff added apart from tires.

*I may have missed a more recent blog post, in which case adjust the time spans accordingly.

 

Tire thermals were also mentioned as being worked on in the background in the 0.27 devblog in December of 2022.

 

Iracing players say that their tire model is unrealistic after the grip limit is reached, so it's unlikely that their current tire physics uses any in depth real world data.

 

As long as it allows me to put tire chains on it eventually and allow buses to have snow chains, I'll be happy

 

scintilla on chinglings is gonna be mad
