I took it back to the dealer twice for same problem. Vibration very evident at speeds near 80mph or over. Speed in Utah in many places is 80 mph. Dealer rotated tires on wheels, as one was 4 ounces off, rebalanced with pressure weight. Problem stil evident after both visits. Service manager drove vehicle and observed same problem. Service manager stated problem is typical of radiant problem in body, would be worse in pick up truck. Suggested better tires in future, but did not replace tires. Future trips are done to parks with lower speed. I suggest buyer should have choice of tires, not what tires they want to use for benefit of deals with the tire manufacturers.
