Like to know C55 Tire Pressure F33/R37 psi is minimum ? And, what is max.?
I am still using 18" stock Pirelli tires

I don't know why, but many car MFG's reccomend stupid tire pressures. Look at the tire size, load carrying ability, and weight distribution of our cars & tell me what makes sense about 32F and 37R??? Nothing, unless you want to guarantee the front end feels like a soft pig & loses traction first.

Since our cars are very nose heavy & have small tires on the front, they respond better with more pressure up front and less in the rear. currently I am running 36-37F and 32R. It makes the front feel a little stiff/harsher, but it handles better. When I took delivery of the car with the stock setup it didn't handle as good as my 2002 BMW 330i (well it still doesn't, but it's better now). Keep in mind my car currently has Continental CS2 tires, and the exact correct pressure does depend on your tire design, but these should be in the ballpark.

33/37 is the recommended pressure from the factory, it is not the minimum. The maximum tire pressure is labled on each tire if you go look at the sidewalls closely.

i run 37psi in teh front and 38psi in teh back... then i drop to 29psi in the rear when im gunna race

Amazing ! 29psi in the rear ? Must be pretty soft and sticky right ? Would that slow you down for 0-100?
I had a go today with the new pressure 33/35 with 4 persons in the car.
I found the acceleration is slower but the car seems more stable when cornering. It 's definitely less bumpy.

It rings my bell !
I probably will try to put the front to be 32-33 and put the rear to 33-34
I agree , 37 for R does not make sense , too much rattling when hits the bumps.
