My 01 came with Aluminum rims from the factory. Less than a year ago I had trouble with a slow leak on one of my tires. Upon further inspection we found that the rim had a small crack on the backside along the bead seal, it wasn't near a wheel weight. I had been having trouble with wheel weights coroding and causing a slow leak along the bead. When we pulled the tire off the rim this crack was about an inch long and headed towards the front edge. Got a used rim from a salvage yard $170 and was back in business. Last night I took my truck in for a small slow leak again. Imagine my surprise when again I have a cracked rim. Right front if it makes a difference. Has anyone else experienced any trouble with these rims? Its a pretty scary thought to think that the tire may not just go flat but that the rim might disintegrate at highway speed. Also the friendly Dodge folks say the rims are only warrantied for 36K miles and of course at the first problem I was at 40K and now I'm at 57K. I've ordered new aftermarket rims with a lifetime guarantee.
