Non standard tyre pressures

[Jon K]

Hi All,

I have 18x8 inch wheels on my 855 225/35 tyres.

Any suggestions as to what the tyre pressures should be?

Cheers

as far as i'm aware, on the same car, different wheels or tyres shouldn't make any difference to the pressure that you put in. something i got told or read ages ago so i'd be interested to know myself if that is true.

As a general rule, the lower the profile the higher the pressure needed. I run the 205/50-16's at 32psi front, 28 rear,

so with the 225/35's i'd start at about 35/36psi front and 30 rear and see how it feels, and how they wear. (shoulders- raise the pressures, centres- lower it)
