I recently replaced the wheels on my 9000i with a set of alloys off a 9000 turbo. The recommended tyre pressure for the steel wheels with 185/65/15 tyres is 30 psi. Should I run the alloys, with 205/55/15 tyres, at the same pressure?

I think the recommended pressure may be 29 psi for the 205/55s. I have 205/65s and run them at 30 psi which I'm sure will be fine for your's as well.

Cheers, Derek, much obliged.
