Ideal tire pressure?
I have 20 inch 343M wheels with MPSS which have been on the car for 4 months with approximately 4K miles. The recommended tire pressure per the sticker is 35 PSI. I feel the ride gets very harsh esp in warm weather after driving for a while on the crappy philadelphia roads. I tried going down on the tire pressure by 1.5 PSI, definitely helps but the steering feels much heavier at lower speeds. Don't know if this a MPSS issue and switching tires might help? What tire pressure do you guys have with your MPSS? Would appreciate any suggestions.

36-37 psi for every day. 38 psi driving long distance with full car. 30-35 on the street drives like the car has a flat tire.

Hmm, that's rather high! Not experimented with such high pressures in the M5 but have tried that in my previous 750Li (19s with a much cushier ride btw). It definitely made it easier to maneuver at lower speeds and generally lighter on its feet but seemed a little wobbly when braking heavily at higher speeds.

I came to those pressures by measuring tire temps at inner, outer and center tread. Gave the most consistent readings all around.
