I would go with the tires may have a marked heavy spot that should be mounted opposite the tire valve or with the tire valve on rims, I forget which was the heavy spot on a rim was marked by GM in past.

It'* also putting the weights on inside only. I'd prefer to use both sides.

Also our local Discount Tire has a Road Force balancer which can fix some uneveness in the rolling roundness under load of tires.

And I've found tires change their seating on the rim during the first few hundred miles of driving and needed to be rebalanced in my past purchases of Michelins. They are close to balanced and many people don't notice the small difference, but I've always love that smooth as glass roll at 60 mph and motice the imbalance.

Roger that, Bob. I never got the tires checed yesterday, because there was seriously a line of people all the way out the door of Discount Tire. I'll go in the middle of the morning on Monday, when it should be less busy.
