Not Unbalanced Tires..what is it??

[Artum Snowbird]

Well I thank you all for your opinions. After dealing with one shop for the new tires, and having them balance the originals, plus the ones they replaced them with, I took it to another shop to have them check out everything underneath. They drove it, then put the wheels onto their state of the art "Road Force" balancer. Two of the tires were out of balance by 2 1/2 ounces and two had to be rotated on the rims to get them within specs for road force.

Likely the old tires just needed a proper balance and I would have been fine. What the heck, new Michelins look pretty good on it!

Now it runs smooth again.
