I have these tires on my 91 GMC Sierra C1500 SC SB RWD pickup. I have rear 275/35r20 front 255/35r20. My pickup I have has 58000 original miles, because it sat for ten years with little movement. The original tires were flat spotted dry rotted so I can't compare the tires to stock. This truck was in in California. Once I got it smogged I drove this truck with these tires and wheels 2800 miles to North Carolina where I'm stationed. During the 5 day trip I encountered HEAVY rain and hot days. These wheels worked flawlessly. Even during twisting roads and the bed loaded, it handled well and during acceleration. I am happy with my purchase.

Tires are usually taken for granted, until the road puts them to the test.
