got bullets 17 inch with the pirellis p zeero from factory the perilli site says there rated at 51psi does that mean were all supposed to have them a 50 or is that just the max and is 30 to 40 psi good for the tires????

 

51 is the max. do not fill them to 51. check the sticker on the inside of your drivers side door it will tell you what psi to use (on the plastic part that is hidden when the door is closed, just open your door and look around and youll see it). Anywhere between 32 and 35 and you should be good.

 

If I recall correctly my door sticker says 35 PSI. Your sticker, however, may be different...

 

32 psi at all four corners is what the factory (and your door sticker) recommends.

 

Yeah, that's what mine says too. Remember that's COLD pressure. Don't measure it after you've been driving for any distance. Maybe better in the morning, after it's been sitting overnight?

 

I had them on the 06 and ran them at 32 in the summer and 34 in the winter.

 

I run mine at 32 and they are wearing very evenly.
