S4's Recommended PSI

Troyz · 07-22-2013, 10:16 AM

I got new S4's to Discount Tire recently and a 4 Wheel alignment at the Dealership. I love these tires!

The dealership swapped the atmosphere in my tires with N and put about 40 PSI. The drivers door said 35PSI so I dropped mine to about 36.5 lbs Cold.

What is the best PSI for daily driving and moderate concerning driving slower?

I take harder corners 85+ MPH. In Texas on the toll (Redneck Autobahn

) the speed limit is up to 85 MPH. I typically exceed that +15 MPH. The Summers temperatures typically are range from 80º-105ºF so there is no reason to put too much N in the tires.

in your case i would use 35psi cold.

i run S04's on my G35C (which is also 35psi recommended cold), and i use 37psi at 80F since my driving is around 70F in the summer early am hours.

i too agree the S04's are great tires. the sidewall looks good too, unlike a lot of the others.
