hey guys bought four new rockathons off a buddy that had won them from a local dealer but heres my problem everytime i am out i pop the inside bead at least two or three times. Doesnt seem to matter what rim or anything fronts or backs they all do it. running 10 inch rims with 36 x 12.5 and all this is at 8-9 pounds which is not low enough for my liking. Any input on this or any little tricks that i can do to help the bead stay on. On a side note when i installed these every one popped on nice and never leaked any air, so i dont know what the deal is?
