I would think about 36 psi, at least that is what they put in my tires at the tire shop (225/45/R17). Is there alot of difference between 225 and 235 in tracking? My spins a little at start (ASR is working untill 30 mph) and I was wandering if I may widen the rear tires up to 235?

Thanks!! The guy at the gas station said it should be between 35-40 psi. I kept them at 40 and was kind of bouncy so I may lower them to 36.
I dont think there would be a great difference between a 225 and 235 however I have ZR rated tires (you sadi you have R?) That may have been the difference. But I don't think you want to have the rears wider than the front. I used to have 235/40 on the rear also for my bimmer and 215/40 in the front (the E36 M3 set up) and it was a lot of hassle because you can't rotate them. So just keep them the same all around.
