Does anyone have a preference? I have the pilot sports on a 997s stock. Max factory 50 psi. I like 45.

 

45 for the back but not 45 all around. Too high. Mine feel best at 37psi in front and 44psi on rears. (997S coupe).

 

36psi x 42psi

 

Mishref, I've gone that route too..a bit more comfy, but I'll top them as soon as they drop below that. Remember these are measured when the car is cold, not returning from a sunday drive. I live in SF so temps are pretty moderate. If your checking your car on the east cost this time of year you have to factor the temperature of you garage and the type of tire your using to nail it down.

 

33/39, as per the manual for a partial load car. On the track I run 29/30 on Hoosiers

 

eclou-i also have a red 997tt-mine is beige inside.

 

I am in Kuwait .. no such thing as cold.

I got nitrogen put into my tires (for free); apparently it helps keep the psi stable under cold/hot.
