kill1308 Posted May 11, 2010 Share Posted May 11, 2010 I put 28 in mine, (235/35/18 front 265/35/18 rear) used to run 32-34 and several people I know who work in motorsport told me that's too high, so I run 28 now. Lots of conflicting reports out there it's hard to know what to believe. Link to comment Share on other sites More sharing options...
Luxluc Posted May 11, 2010 Share Posted May 11, 2010 There is a difference if you run road tires or semi slick tires. On the road tires, I put 34-35 psi when cold ; on my Michelin Pilot Sport Cup (semi slick), I put 29 psi when cold. I was told by the supplier in germany that you can run down to 22psi on the Michelin's when cold. The semi slicks, as they go higher in temps, get higher pressure. My Michelin's are at 33 psi at 40 °C, which is fine for the road. Luc Link to comment Share on other sites More sharing options...
