Max Tire Size On A 18x8 Inch Wheel?

[TDYE522]

I'm new to the board and own a 2008 GMC SIERRA ALL TERRAIN EDITION extended cab shortbed. I am about to order the rough country 3 inch lift and will upgrade tires as well. The kit says that the recomended tire size is a 285/65/18. But I was wanting something maybe just a little larger. The wheels are 18x8 inches. Can I fit a bigger tire on those wheels? Any help would be great.

I got on tire rack and looked up the tire I would like to go with (bf goodwrench AT) and rough country says to go with a 285/65/18 and it measures 11.5 inches wide and 32.8 inches tall. After seeing a truck in person with a level lift and the 285s, I would like something a little bigger. The BFG AT in a 305/65/18 measures 12.2 wide and 33.7 tall. How much of an issue would it be to put that on the stock 8 inch rim? And what about rubbing?

I think that you can get away with that tire size/wheel size combo. But just FYI that is about the limits. You would be better off running a wider wheel or a skinnier tire just to get better wear. With that said I am currently running a 305/55/20 on a 20x8.5" wheel and I am getting pretty good wear and excellent mileage. thats a 12" wide tire on a 8.5" wheel, so pretty close to what ur doing.
