Friction is weird, so yeah, you probably do have to derive a formula from empirical data.

An example of friction being weird: Most material interfaces have a higher coefficient of static friction, than of dynamic friction. But aluminum to aluminum has a higher coefficient of dynamic friction than static friction.

And when you consider automobile tires, think about what might be happening when the situation in my avatar occurs....

Good luck!
