What psi do people run.

Post by afennell » Fri Jan 20, 2017 12:22 am

Just wondering what psi people run, I know it says inside the drivers door. But wondering if people prefer lower pressure on or in their tyres?

worth highlighting this will vary by wheel type, and car (appreciate this was in M section, but alloys really do span all versions as are probably the most commonly swapped component)

Also worth mentioning - it will also vary by tire (or tyre on your side of the pond). My original Continentals wore evenly at 30-32psi. My first set of Bridgestone Pole Position S04 wore excessively in the center (rear tires) running the same pressure. I dropped the pressure down to 28-30psi on my 2nd set of Pole Position S04 and the tire worn more evenly, but still with a slightly more wear toward the center. So it appeared that these Bridgestones like to be at lower pressure than the OE Conti's.
