Daz 330 Cs Posted July 29, 2016 Report Share Posted July 29, 2016 (edited) Welcome to the Zone You should have a sticker on the inside of the drivers door, from memory it's 36 front, 42 rear. I always found the rears too 'crashy' so reduced them a tad. Edited July 29, 2016 by Daz 330 Cs Link to comment Share on other sites More sharing options...
Tim-Ci Posted August 1, 2016 Report Share Posted August 1, 2016 (edited) Yes the above sounds similar to the pressures on my 'vert with 18s. I tried running the pressures a few psi higher than the unloaded numbers, for better tyre life/mpg, mid-way in between the unloaded and fully loaded numbers, and got a lot of tyre wear on the rears in the centre of the tyre only. So it does seem like the recommmended rear pressures are on the borderline of being too high. Seems funny that the rears are recomended to be 6psi higher than the fronts when the car's weight distribution is pretty much 50:50, unless it's due to the wider tyres in some way.

R11CH Posted August 1, 2016 Report Share Posted August 1, 2016 Always put 32psi front and 34psi rear on mine, wears evenly, not crashy and feels perfect to me. Link to comment Share on other sites More sharing options...

This is what happened when I ran psi to the book. 32 all round gives a good ride with handling to match and even tyre wear. Link to comment Share on other sites More sharing options...
