I have a Tuff Country 5" suspension and a 3" body lift and with 38" hawgs on 12" wide wheels I had a little rub, but only on my bumper. Mine is a sport so the bumper is a little bigger and also the 12" wheels stick 'em out a little farther. If your Ram isn't a sport and you use a 9. 75" rim, a 2" leveling kit still won't cut it. A 2" kit will get you 35"s on a 9. 75, and will rub the plastic inner fender. Go with a 4. 5" or 5". Also, Hawgs are C rated and if you tow much more than a Jet Ski, they will come apart. Trust me, this is why I don't have them anymore! D rated tires at least. I know Hawgs say 3160lbs per tire, it's not that, it's the 35lbs max pressure. This causes heat, which causes separation. I was lucky, I figure 100 more miles on my trip pulling my toy hauler and I would have had a tire failure. Both rears to be exact. Swamper and some others have big tires that are D or E rated, go with the heaviest ply tire to be safe. How does that saying go "so much is riding on your tires" It's true. Hope this helped!
