Tire pressure - Opinions- advice sought

[Hroussard]

My 996 TT 2003 runs on 19 inch Sportec's. The tires are; front 225/35/ZR19, back 315/25/ZR19. Continental ContactSport2

Recommendation for tire pressure please ... 50/50 town / freeway driving, no tracking.

Has anybody these same tires or at least the same sizes?

Thanks a million.

I suggest you stick with factory/owners manual pressures for the street.

Aren't the factory pressure values based on factory 18" tires? The OP is running 19's (if that even matters) and so am I.

The 997TT comes with 19" wheels and the tire pressures are the same as 996TT and 18" wheels.

Check the two TSBs if you like.

Loren, thank you, so.... I am trying to find those TSB's but they are hiding. What is the recommended pressure?? I will check my users guide tonight but I wonder as indeed I have the 19's and boy, they are skinny :-) I am wondering.

what is part v. full load?

Full would be at the vehicles weight capacity (loaded with people and luggage) - partial is anything other than full.
