I did some research last year about procedural tire rendering.
It turned out the main problem is, you don’t want to generate & draw the tires of all vehicles in the game one at a time. You need to batch them.
So the vehicle API requires the ability to declare a tire model. E.g. for the F-22, this would be Michelin 23.5 x 7.5-10 for the nose wheel and Michelin 37 x 11.5-18 for the main gear. The engine would then fetch data that is common to all tires of the respective model (e.g. the vertex buffers for profile information and the textures for imprints) and render all tires of the same model in one pass.
