Tire Pressure
The original tires for my 1977 911S were 185/70 VR 15 and Porsche recommended 29psi on the front, and 34 psi on the back - I am now using Vredestein 195/65 R15.
The question is if that tire pressure still applies? or should I increase or decrease the pressure?

Stick with the same PSI for your new tires. I am told 28 front and 36 rear for my SC by many folks I trust.
