i got 35psi also...i actually keep it a bit higher (better mileage) if i am going to drive hard i will drop it a bit but for city driving i keep it around 37.

Thanks

Therefore, I suspect the reason for the increased pressure requirement is to force the primary wear on the center of the tires and to reduce the wear on the extreme sides of the tread common to feathering. That;s my guess anyway.

It could also have something to do with the redesign of the tire too. From what I understand, the inflation pressure has a lot to do with the load carrying capacity.
When you change tire brands and sizes, you're supposed to adjust the tire pressure according to the load rating of the tire. That's what that 91y or 97v (I can't remember from the top of my head) code next to the tire size is supposed to mean. I went through a "tire pressure chart" and ended up going 40psi up front and 37psi in the rear to make my load capacity equivalent to the OEM's 35psi.
I don't know why tire manufacturers and resellers don't make that known.
So, perhaps the 32psi for the roadster is based on a tire that is slightly different from my OEM tires.
