I bought some new tires and when I got home I noticed that one was leaking. Instead of towing the RV back, I decided to remove the wheel myself. I couldn't get it loose. I used an impact wrench and it couldn't budge it. I then tried a breaker bar with a 3 foot long piece of pipe and that didn't work. I'm not a small guy. I'm over 6 feet tall and weigh 290 lbs and was a diesel mechanic for many years. I ended up taking it back to the tire place and letting them deal with it and they broke a wheel stud trying to get it loose. I had them remove and torque all of the lugs to the proper rating (80 ft/lbs). I would have been really angry if I had to change a tire in the middle of nowhere.
