Karl, I once had a new set of Goodyear tires put on my Jeep Wagoneer.
Around 15,000 miles I began having vibration troubles. Finally replaced
the tires - no more vibration. Finally figured out the tires had gone
out of round. Actually it was like the tread was working loose in
patches, making the tire out of round but not the tire case. It was
weird. Goodyear made good on them though.

Regards,
