I have the same issue. I have had it balanced 3 times. Stock everything, minus the tune. Going to try the dealer, and see how they manage to do on the balancing job.

Thanks for all the feedback! The tires were balanced with a Road Force Balancer. The problem is pretty much evident at all speeds. I will relay all the input to the owner. The "washers", among other things, sound like a great place to start. Balancing again can't hurt either!

Thanks all!

The washers wont affect stock wheels............
