any explanation on the parameters of the tire model?
any info about the temperature/pressure influence to the grip?
The tire models I am writing about are contained in vdrift source code github.com/VDrift/vdrift and also here (friction curve editors) github.com/logzero/vdrift-tools
Tire pressure is a parameter in the physical model affecting contact patch size and pressure. It should also have some effect on carcass stiffness, but I have no data on that. Currently a fixed pressure value is used for vdrift tires.
Temperature is a very interesting parameter. Some might argue the most important one, responsible for the nonlinear friction behavior. Interesting for me is probably how it affects peak friction and cornering stiffness.
I haven't looked into implementing it yet. Here is a paper that might be a good starting point: publications.lib.chalmers.se/records/fulltext/143233.pdf
