I put the KO2's on the chase truck and started getting a vibration about 55-65 mph. Took them back to Discount tire who told me I had a bent rim. Ordered 4 new wheels and had Discount re-mount everything. Still had the same issues over the next 1000 miles or so. Finally took the truck over to another shop who shaved the tires and now the issue is gone. Anyone else have this issue?
