@Discount Tire I had the wheels and tires re-balanced at a different Discount Tire in my city and they said they were out of balance (they were first balanced at a different Discount). This time they said they Dynamically balanced them and added some weights but I'm still getting the same vibration around 60mph. I hate to take it back a third time as I'm feeling like a nuisance. Any suggestions?I apologize tires are not balanced rayzjeep. Hub rings porpoise is to help center the wheels on your hub not specifically to balance the assembly. I would recommend going back to your local Discount Tire store to have them re-balanced.
