Either my tires have been out of balance for a long time or my shocks are worn out since my tires have formed uneven wear along the inside tread blocks. I used to only notice it a little at 60+ mph but now I can feel it at lower speeds. I made an attempt to rebalance all the tires, but the vibration continues. I guess my biggest question is, is it possible to even out the tires eventually after fixing the cause of the problem or will it still continue to stay that way or even get worse?
