I'm looking at getting new tires and rims. I have a set of 26'' ITP ATR's on my stock rims. I personally liked the ATR's but I'm thinking I'm going to get something that likes a little more mud and trail. The stuff I ride is either loose rocky, loose coal, hard packed dirt, mud, just about anything you can think of but sand. I don't want something that will shake me to death. so what do you think I should get? Size would help also.
