Tyre pressures

[mild2wild]

Hi All...I run 16 inch rims on my 460i with 225x50 Yokahama A510's. I am wondering what would be the right pressures to run them at, the original 15 inch wheel and tyres should run at 22 front 24 rear.

Weeeeeeeeeeeeeelllll, just pump them up until the rims come off the floor, then add 5 psi and you won't be far off..... ;-D

For the same contact patch size use the same pressures (car weight is approx. constant).
