tyre pressure

[teejay43]

Having new tyres tomorrow would like to know what is the right pressure for 225/45/17 also 255/40/17 on a daily to give best grip and wear
thanks in advance guys

I used to run round 30 psi in my 255 rears but found the middle of the tyre 'sagged', so the outer wdges used to wear at a higher rate than the middle of the tyre.

When I changed my tyres I had the geometry set up properly and have run around 31 psi front and 37 psi rear. The grip has been brilliant and am very happy with tyre wear etc too..
