Way, way back in time, I drove a '57 Ford in the canyons.
Front pressure was 50 PSI and rear pressure was 35 PSI (cold, of course).
Tire wear was even. No wearing out in the center.
Setting up a 4 wheel drift was easy, and it was easy to maintain it through the curve.
Most tires were rated a max pressure of 32 PSI.
A friend of mine had a '62 Corvair. He ran the same pressures but on opposite ends (35ft/50rr).
We both lived through our blatant disregard for the max. pressure on the sidewall. :shock:
The car that understeered had a higher pressure on the front to create a more neutral handling.
The car that oversteered had a higher pressure on the rear to create a more neutral handling.
This is just a demonstration of how the difference in tire pressure will affect the handling of a vehicle.
Maybe some high performance bike riders have something to say. :?
