My buddys in Germany have quite a discussion about the correct tire pressure for a SPF with 235/60/15 and 275/60/15 for track and road use.
I refered them to the rogerkraus and tirerack site, but they weren’t satisfied.
This is apparently what the manual says:
18 p.s.i (COLD) for normal driving
25 p.s.i (COLD) for performance driving
I am surprised by the high cold pressure for track use, which would go up to 35 to 40PSI when hot?
