Straight answer here.
You will rub for sure with 33x12.5 tires on stock wheels.
That is 100%
Heck, even at 295/60/20 tires you'll rub. Which is a 34" tire
You will require spacers for either setup or an aftermarket rim with negative offset.
Stock rims are 20x9, +19 offset.
If you don't believe me, take your tape measure and measure from your tire to your A arm. You have max 1/2" space till it rubs.
Many members here are running 295/60 and 33/12.5 tires and 295 requires 1/4" spacer and 33x12.5 requires a larger spacer but anything more than 1/4" I recommend another set of aftermarket rims with lower offset. Like a 0 offset.
295/60 = 0.4" wider on either side of wha you have now
305/55 = 0.6" wider on either side.
315/55 = 0.8" " " " "
You have to do either of the following or a combo depending on tire size selected.
- level your truck
- use spacers
- get aftermarket rims
Cheapest of the 3 is 1/4" spacers and then leveling.
Its not more so the height, rather the width...again pertaining to the tire sizes mentioned above.
Hope this helps
