Tire Pressure tooo high - Check it
I decided to check my tire pressure since dealers sometimes forgot to check this when they deliver a car.
I was sitting at 38-39 psi all around. I set the pressure to 36psi all around (stock), and you wouldn't believe the ride difference 2+psi makes on run flats. It's a much smother ride.

Yikes!
The only reason I didn't the first day is my dealership always checks them at delivery time.

I learned my lesson about this when I bought the GTO. The spec on them is 38/40 but for some reason they jack them up to around 50PIS for shipping. A lot of the cars were sitting on the dealer lots like that, including mine. A few PSI really makes a difference on modern low profile tires.

Mine was a couple pounds high also, but I'm running 37 front, 36 rear now.
phaze, 32-33 is too low for low-aspect ratio 18s. Too easy to damage tires or wheels. |

I adjusted mine this past weekend. I did 32psi up front and 36 in back. Was trying to dial out a bit of understeer.

Is anyone going to switch to Nitrogen in their tires? I want too, but I need to find some in the Chicago area.
