Default 430 Spider tire pressures?

Hi,

Just got a new 430 Spider, and have a question on pressures.

The manual says 30.8/35.3.
The quick quide says 32.3/35.3.
The door says 32/35.

Car has PS2's.

What do you think is the most correct/newest recommendation?

Thanks!

I see about a 3 lb split front to rear. go with that. Check the tire side wall for pressures. Drive it the way you like and see if you can tell the difference by trying different pressures. For any track use, a tire pyrometer will tell you what pressures the tire wants. Make small adjustments from that info to balance the car to your feel.
