Was wondering how much air should I put in my tires,owner manual call for 36 psi front & rear,when I when in for the PPI we check the pressure the PO was driving around with 20 psi all around witch to me is not enougth air for any kind of tires ,the car is shod with (Goodrich -g force -t/a kdw2) 225/45 zr 17 frt--255/40 zr17 rear . I'm planning to rides on those for a while since there is 70% treads left on them. they are noisy at high speed and don't realy feel comfortable with them,I'm not gone a be traking the car, only crusing around and once in a while HWY driving,so if you guys can give me a little advice as to witch brand I should buy when time come I'll realy appreciate it.I had FALKEN 452 on the 944 and the are the best tires that I ever mounted on a porsche.*******THANK'S for all the responde on the (AMAZONE GREEN ?)

rpm's S2

For daily driving and highway trips I run 34 psi all around. This is a bit softer over bumps and interstate expansion joints. For fun drives and road events I go with the owner's manual 36 psi recommendation. My wife can tell if I have gone to 36 when she is in the car.

The real key is to regularly check tire pressure!

As for tire brands, everyone has an opinion. The Sumitomo HTRZIII seems to offer a good compromise between price, performance, and durability. I have 12k on mine and am very happy with them.

I concur with 34 psi ( Kumho Ecsta SPT's )...

maybe she has a sister ?
