Whatever rim size you buy the tire for!
Just kidding! There are really no performance advantages to running a certain wheel size. If you're running the 33's on stock wheels, you shouldn't have any issues with fitment.
You can go as small as a 16" wheel with no modifications. If you want to run a 15" wheel, you will have to grind the caliper bracket down slightly depending on the wheel. All I had to do was take a flapper wheel on an angle grinder and clearance it maybe a quarter of an inch.
Hope this helps! Feel free to PM me if you have any questions.
