New FR 22's -Question concerning vibration.

I've got a situation that I've not run across on this forum yet.

I just got my FR 22's with 305-35-22 Pirelli's.

When I'm first driving the Jeep I get a vibration between 62-68 mph from my tires/wheels. It lasts about 6 miles then dissipates. Also, I should mention that it not been overly hot here lately...around a high of 59 degree Fahrenheit.

At the most, the Jeep is sitting overnight between trips. I'm wondering if I should be concerned that the wheels aren't properly balanced or that there are problems with the FR 22's being out of round (as I've read about on this forum).

I'm thinking that I'm getting small flat spots on the tires from sitting overnight, & once I've driven 6 miles or so, the flat spots disappear. I'm hopeful that as the weather gets hotter I won't get these flat spot issues any longer.

Am I off base on this not being an issue?

Its a balance issue. I doubt the world class . pirellis would get a flat spot over night. I have the same tires and they dont. My reps were the same till infound a good shop to balance them.

The shop that installed them is one of the best in the area and use the Hunter Roadforce balancing equipment.

I'll have to give them a call.
