I usually hit around 60 when I start feeling the vibrations the whole front of the car shakes, including the steering wheel is highly noticeable. It gets calmer after a period of time. I took it back to the dealer and they rebalanced it. I bought the truck from the dealership with 24" wheels on it. They said they were offered by Chevy as an after market wheel. Should I take it to another place to balance it?
