It was a stock truck and Toyo A/T. If you were to run a leveling kit, you'd surely be fine. A more aggressive tire would likely cause a problem, though. (I.e. couldn't have run a mud-terrain or anything with side bit). On the factory wheels, I had to trim a touch of inner fender liner, that was it.

 

I have the Toyo Open Country AT2 on the stock wheels...295/65/20 and NO rubbing.

No kits, just the Snow Plow package with the 6,000 springs.
