I did a search and found a lot of great info. My question is..... I have a 2WD and the rim size is 15x6JJ. First, what does this mean? 15" dia and 6" wide? The 31x10.5x15 Revo's have a rim dimension of 7-9". I wasn't sure if they would fit my rim. The 31x10.5 were optional on the 4WD but not the 2WD. The owners manual calls out a rim size of 15x7JJ. Also, explain the tire size while you're at it. 31x10.5x15. 31" dia. 10.5" wide and 15" rim? <img src="/forums/images/graemlins/confused.gif" alt="" />

I would like to go bigger but am unsure and don't want to waste shipping getting the tires here only to have to return them. Thanks
