Don't remember exactly, but if memory serves it's something like 32 front, 36 rear. My suggestion is to check pressures frequently, since it significantly affects handling as well as tire wear.

Use these figures, posted usually on a sticker inside the passenger door. For non-Z rated tires, I usually increase pressure by 4-7 psi for track events. Z-rated tires should always be driven at the specified sticker pressure, whether track or street. Always check pressures cold. allowances are made by the engineers for increased pressure with tire warming Marq J Ruben (Qferrari) Junior Member Username: Qferrari Post Number: 75 Registered: 2-2002 Posted on Tuesday, July 23, 2002 - 5:48 am:    36 front, 37 rear - 328 Peter S�derlund /328 GTB -88 (Corsa) Junior Member Username: Corsa Post Number: 219 Registered: 4-2001 Posted on Tuesday, July 23, 2002 - 3:46 am:    I run 32,5 front and 34 rear, cold pressure, which will be 37 front and 39 rear hot on my 328 with Y AVS Sport.

So if you have excess traction at one end of the car, and want it better ballanced, add air to that (excess traction) end of the car. I use this all the time to ballance out the car for general neutrality, and just a hint of oversteer.

If you do not have a manual. I could fax you the pg. which also gives pressure tuning tips(if x is happening do this with F or R pressure. I just put on S-03s this weekend, max pressure is 51 lbs. I'm running 34 F 36 R. Started at 44 F and R it was like a steamroller, it did bite hard. bruce wellington (Bws88tr) Member Username: Bws88tr Post Number: 549 Registered: 4-2002 Posted on Monday, July 22, 2002 - 8:55 am:    todd, 22psi, you must be sleeping.. ill see you at the bbq bruce Todd Gieger (Todd328gts) New member Username: Todd328gts Post Number: 33 Registered: 6-2002 Posted on Monday, July 22, 2002 - 8:48 am:    This sight never ceases to amaze me...I was just about to do a search on tire pressure b/c my tires were at 22 psi when I checked them for the 1st time this weekend. I will try at 32/34. Thanks Bruce and Randy. bruce wellington (Bws88tr) Member Username: Bws88tr Post Number: 547 Registered: 4-2002 Posted on Monday, July 22, 2002 - 8:41 am:    ken mine is 32 front cold 34 or so back Ken Ross (Kdross) Junior Member Username: Kdross Post Number: 92 Registered: 2-2002 Posted on Monday, July 22, 2002 - 8:38 am:    Thanks Randy. Ken Randy (Schatten) Member Username: Schatten Post Number: 343 Registered: 4-2001 Posted on Monday, July 22, 2002 - 12:54 am:    You might want to keep them at or around 32 or even 34 psi COLD and then adjust from there. Sure you can run them at a higher psi rating but the ride will be slightly harsher so it all depends on how you drive the car. also, in balancing out the car with minor adjustments such as tire pressures - get the fronts where you want them and then adjust the rears higher or lower. this provides proper turn-in for the fronts and adjustment of any over/understeer left to the rear. Ken Ross (Kdross) Junior Member Username: Kdross Post Number: 91 Registered: 2-2002 Posted on Sunday, July 21, 2002 - 11:10 pm:    I recently purchased a set of Dunlop SP8000 tires for my 308 QV. The tires have a max. pressure of 44 psi. What is the proper psi for me to fill the tires with? I have always had tires with a lower psi rating and usually kept them at 32 psi. TIA.
