Can car tires slip against a wheel rim under hard braking?
Is it possible for the rubber of a car tire to slip versus its rim when you brake hard? Or is the road friction always going to be less than that of the tire rubber against the rim?
When a tire is mounted on a rim, I've seen sealant used, especially on older rims, to stop air leaks. Is that also to act like a glue to help stop the rubber slipping, or is it just to stop leaks?
Just wondering

It's the air pressure....
35 psi pushing out against the sidewall and bead, figure half the sidewall load is held by the tread cross section and the other half pushes bead against the rim. 25" tall tire, 17" rim, 4" sidewall, just guessing...1/2" bead.
So 2.5" x 53" circumference x 2 sides x 35psi
what do ya get?
About 9300 lbs total bead to rim pressure on each wheel.
If your tire pressure is very very low then I think it's possible.
