What tire pressures should I run? I just got my ride back from it's 8000km check and they adjusted the tire pressure to 32 all around. As recommended in the manual I had things set at 36 front and 33 rear. When I called Audi they said that is just a recommendation and they set all their's between 32 and 34. Who is right.

 

I have the 17" wheels, riding Conti ProContacts, on my 2007 3.2. audi recommended presure is 41 front, 38 rear. I've just kept all at 41.

 

There should be a sticker on the door post that you can see when you open the driver side door.

 

Tires vary with tire size 38to 41 is probaly too much! You should go with the tire shops recommended inflation probaly 32-35 and audi does recommend to run 2-3psi difference from front to back.Your tires have a stiff side wall and are made to run a little soft.Running tires rock solid are bad for performance a grip, all it will increase is gas milage if you don't care about damaging your tires.The side wall my say MAX PSI45 or 52 BUT! thats not thepressure you could/should run.

 

There was a post recently about an A3wearing out the centre of the tire treads. If I remember, the pressure had been set in the 40's. There should also be a "maximum inflation" number on the sidewall.

 

problem with the P6's is they are insanely loud at anything under 36psi on 17" wheels. I am running at 38f and 36r and have to add air every other week to keep them quiet enough to not drive me insane. Cant wait to get new tires next week!

 

I ran 38F&R with my Pirelli replacements, Bridgestone RE960's, 31k later, even wear (still 6/32nds of the original 11/32nds remaining), great performance, and still relatively quiet

Since I had coilovers installed, I have lowered the tire pressure to 36F&R.

IMHO, oem tire pressure's are too low!!!

Add 3psi to oem and adjust as necessary depending on thread wear & performance. [8D]

 

32 all around here, when the tires run they get hotter and the psi goes up so too high it might be bad

 

Higher tire pressure keeps hot/cold fluctuations down. As for recommendations, my manualadvises using what's recommended in the door sticker, door sticker advises 41 front and 38 rear, and the max pressure posted on the tire itself is 52 I think.

Tire pressure recommendations have too many variables too - 3.2 has different recommendations than 2.0, plus I'm running 17" all season and not the 18" performance summer.

 

B5's have a smaller profile tire than the B7's + rim/tire size will change also thetire brand can change your PSI, rim width, and side wall strength all variables.Good luck finding a happy medium.
