I have a 21 Silverado LT 4x4 with the 3.0 Duramax and the stock 22x9 wheels with 275/50/22 tires. Will be needing tires soon and have started looking into what it would take to squeeze 35x12.50's on the truck. Doesn't necessarily have to be 12.5 wide, I'm mainly looking for a little taller tire but those 35/12.50's sure would look good if it's possible without going too crazy. Anyone have something similar? What type of lift/mods did you have to do to make them fit?
