After rebalancing and rotating the tires the other day I got a vibration around 50-55.
I watched the tech balance all the tires to "0". So the tire is balanced perfect but still is out of balance.
I've came to the conclusion the tire either has a busted belt or is out of round.
I've had this tire on the jeep 3 times now and taken it back off after a few hundred miles each time. I always figured the tech got lazy on one wheel and didn't get it completely balanced, but this time I watched him closely....
I put it back on the tailgate, I'll see if I can get it replaced.
