Q: My car shakes when I go 65-75 miles per hour. I had the wheels aligned but that didn’t fix the problem. My brother-in-law suggested new tires. The tires look OK. What could be wrong?

A: My first suggestion is to have the tires inspected and rebalanced. The shaking is typical of a tire that is out of balance. Tires are balanced with metal weights. Over time, weights can come off. The other possible problem is that one of the tires is damaged and has a cord separation, which could cause the vibration and lead to a tire blowout. Having the tires inspected will rule out a tire problem.
