New Sierra Denali HD 2500 - upsizing stock tires/wheels?

Nice truck. My 03 Sierra had factory 20's. Loved the looks, hated the handling. My 11 Sierra has the 18's and I'll never go back to the 20's regardless of good they look.

GM never made 20's in 03... Doubt it was due to the wheels.******ride on the 03 was more likely due to over cranking the T-bars and overextending the shocks. Very common mistake amongst GM owners. With the right tire your not going to feel much of a difference in ride between 18" and 20" rims.
