Yes, that's a 33" tire. Should fit without an issue. However, it will throw off your speedometer by about 2mph.

Guys, I've literally read a thousand posts on tire sizes, and I am more confused now than when I started I have a 2017 GMC Sierra 1500 6.2L 4x2 Denali on order. When the truck comes in, the dealer is going to install a leveling kit (I don't know which one, but I do know it will be one that works perfectly with the MRC on the Denali). I am planning to keep the 20" factory rims and replace the tires with something more aggressive to fill the wheel wells out more. My question is this: What is the maximum tire size I can go with to avoid any rubbing with zero modifications (other than my level kit)? To be clear, I don't want to do any cutting, trimming, zip tying, etc. or have to add spacers. From what I read there are so many opinions on this. I know with 100% certainty that 275/60/R20's will fit, but these aren't much different than factory tires. However, what about the following sizes: 275/65/R20 285/60/R20 295/60/R20 295/55/R20 305/55/R20 Some say all these will fit with no rub, and others say some do and some don't. Can someone who has tried and tested this please give me some advice. Thanks! PS: If it makes a difference I'm looking at BFG All-Terrain A/T KO2's, Toyo Open Country AT2's or Nitto Terra Grappler G2's... I also know that not all these tires are not available in all the sizes above.
