    Default 225/45/17's : What tyre pressure to run at?

    Just hammered my wallet for 4 new tyres.

    I went from standard 215's up to 225/45/17's.

    For those who have made this very common switch to the new size/profile, what pressures do you recommend I run them at?.

    Thanks.

    The tyre pressures are listed in the manual for 225's - with mine (1.8) the pressures were the same as the 215's, I don't know about the 3.0 diesel.

    You're likely running XL tyres, so the ride will be rock hard anyway. Pressure should be the same as the 215s.
