Hughes; It's a tire prob. It did not do it with the stock tires.
Torch654; I thought of that, But I've got 3/4 rides on them now and I think I'm just going to replace them with some Maxxis!
It's not a 18/19 inch rear wheel thing, as my rear wheel is not out of balance, just the front, and I think we all have the same fornt size rim?
