Does rear tires have to balanced?
I noticed a slight vibration on my winter set at high speeds. I had the tires checked at a tire shop and they said it wasn't balanced correctly. I had them fix the front tires and when I asked them to check the rears, they said it wasn't required. Is that true?
Also, what kind of damage can I have endured by driving with unbalanced tires, it was a long trip (300miles) at mainly highway speeds.
Thanks for any inputs.
