Running with a high speed on a curb (i am thinking about one of those on fernbay)or a speedbump, should cause damage to the wheels(and i mean both rims and tyres).

Imagine how hard it would be to do only one competitive lap on fernbay black... those blown tyres, and bent rims...

suggested before (by me ) but as i recently realised its not possible with the current tyre model

couldnt find it..
theese are sad news...
maybe some kind of override : extreme heating of the tire at the hitted spot
i know that tyre would blow if theres any spot abowe a certain temperature

why shouldn't the current tyre model let it?

The tyres deform, if you can deform it around a shape (the rim) and make that rim bendable like the rest of the car I think it's possible.

Although rims are tough to break, you should be able to bend pieces of the outside.

Correct me If I'm wrong.

because the current tyre model only supports one single contact patch and only checks for collisions between the tyre and objects at the bottom of the tyre (in car coordinates)

note how the tyre sinks into the ground and the car is supported by the bottom bit of the tyre

Well since LFS wasn't designed to do wheelies I can't imagine that that's not down to the fact that it's all screwed up!

We'd have to test by adjusting camber angles, toe and pressures to see about contact patches and stuff! D;

So that is why there are no offroad tracks
Now i clearly understand. To render proper wheelie, lfs should have to calculate every single one contact patch at the same time, i think modern computers can handle that.
