What PSI do you inflate your tires?

I have always inflated mine to 32 psi

On the inside of door frame of the drivers side door is there recommended tire inflation's. I have always just used that. It will cover several different tire sizes and inflation's.

28 / 32 with pure nitrogen

What does the nitrogen do?

[///Sniper535]

more stable during temperature changes

[russiankid]

32/35.

Air is like 80% nitrogen... but oxygen is the variable that expands when heated up... so hot tire always has more PSI... same for super cold winter and PSI falls.

Pure Nitrogen is more stable and used by all racing cars. They can't have tire pressure changing on them while racing.

I never used it... didn't want to pay for it.

I go right between the 2 options with 1-2 lbs more in front due to the extra weight of the V8 the lower setting the front tires wear on the outside edges of the front tires. you can go with the minimal settings. More pressure on the rear is for more controll in cornering. 32/32 square is wrong for these cars.

39F/41R, keeps the lowered suspension-negative camber, excessive inside wear at bay. (Man, what an ugly sentence!)

I've had good success with this for the two years I've owned the car. These pressures worked with the 18" setup, the stock 15"ers, and the E39 16"ers on there now.

Granted I am in Germany and can drive at 100+mph at will...the car does feel squishy at lower pressures though. Not something I want when driving at speed!

P.S. I run the same pressures with my '08, sport suspended, 17" wheeled car. Damn, run flats!
