i had recently put 22x11x9 shredders on my warrior and ever since then it wanted to vibrate when you would get into 4th, 5th, 6th gear low end only though, right when you shifted it and gassed it pretty hard it wanted to vibrate. i took the tires off and it stopped, the guy i bought them from said they would be great tires. i love the tread and traction it gave me, but what could make it vibrate this bad. is it becaude of the size?????? i put my spider trax back on it and it didnt do it anyumore, and i also tried the stock ones and it didnt do it there either. i really want the shredder/holeshot tread though. what do you suggest? maybe 20" tires????
