20" x 9" wheels and tires

[Jmtn51]

Hello, I'm new here and just recently purchased a 2011 GMC sierra extended cab and would like to purchase a tire and wheel set in the near future. I also plan on buying either a 2" or 2.5" (front) leveling kit as well. So my question is will I be able to fit a 33" x 12.5" x 20" tire or a 305/55R20 tire on here? Please include all details such as wheel offset and wheel size/tire size and whether or not the tire rubs and how much trim is necessary. Thank you all for your time and all answers are greatly appreciated!

May rub a little at full lock. I have 295/55/20 nitto trail grapplers. 20x8.5 wheels with a 5.9 backspacing and at full lock tires rub sway bar a little. U should be ok as long as the wheels have a 5.5 backspace. Get the 2.5 leveling kit.
