    yes, depending on your suspension set up, or road conditions some people run lower pressures for smoothness handleing etc!

    Is is not best to have the correct tyre pressure for all round driving on public roads and changing the tyre pressure for track use depending on what track your on ?

    I have Contours on my car, and run 36PSI rear, and 34PSI front....

    I think I might have to lower the pressure on the front... It seems abit "floaty" around some tighter bends when accelerating. And it's not bushes

    So will be interesting to see what everyone else runs, then I might be able to make a decision as to what to run in the front !

    My owners manual and the sticker on the inside of the door sill both say 2.4 front and 2.9 back (psi: 36,42). It says this with a picture of 4 people, so I assume this is the standard pressure, which is designed to cope with the load of up to the equivalent of 4 people, so I put slightly less in with 34 front and 40 rear. I was initially shocked at the recommended pressures, especially the rears, but the car feels fine at these levels and I have a feeling the the lower profile of the 18" tyre, perhaps coupled with the sports suspension means higher pressures are required.

    I personally am not going to drop below 34,40, as I think you should follow the guidelines per the manual, I'm sure the car has been designed to work best with these pressures in mind. Saying that, 33,37 doesn't sound too bad, especially if you don't have sports suspension or drive mainly without passengers.
