275 / 60 R20 so 32.9 I believe it equates to.
I wanted to go 305 / 55 R20 (12 wide, 33.2 inch tall) but the guy said there wouldn't be enough back spacing with stock rim offsets. However, looks like the @SuperAllTerrain (post right below mine) did it...
I picked up a 2017 Sierra All-Terrain on the weekend.
Mods on the truck so far:
- 2 inch leveling kit for the front
- 33 inch Duratrac tires
- 20% tint on the front
- Xpel protective film on front bumper, hood, grill, mirror caps, headlights / fog lights, and A pillars.
No chrome for 2017 !
