I've looked through about 14 pages and the best advice I can find about how big I can go is 37x12.50

Will any modifications need to be done to run those on a bone stock sut with air bags? I rarely have went off road in my H3 (still have it) so I don't see myself taking the sut off road much. I just want a nice compromise between on and off road.

The tires on the sut are shot so I plan on ordering a new set of 5 in the next couple of days.

 

All depends on each rig. Some have been able to run 37's no problem while others rubbed so bad they needed bigger offset wheels. My stock 35's rubbed on my sway bar at full lock so I never gave 37's a try, plus I wanted to fit in my garage with the roof rack.


Now with my green keys, leveled, and the big offset wheels I have, I am sure I could easily run 37's but then I probably wouldn't fit in the garage. Given mine is paid off she's just a garage queen now.
