Question

New kumho tires vabrates at 55 to 70 mph?

Answer 1

Along with the other answers, check to see if the tires are out of round.  An out of round tire will always cause vibration no matter how much it is balanced.

Answer 2

First, talk with the folks where you bought your tires. Most tire stores want your tires to be balanced and will want to make sure you are satisfied because word of mouth is the best form of advertising. So, take them back and have them rebalanced first...ask to watch the tires being balanced with the manager...to make sure the work is done correctly. If the tires are out of round then the manufacturer's warranty will cover ride disturbances within the first 2/32's of tread wear. Lastly, if all else fails then call Kumho customer service at 1-800-HI-KUMHO

Answer 3

either you need to bring them back and get some new tires, or you need to get someone to look at your ball joints.  

most likely, it is a combo of both.

Answer 4

Answer 5
