I once had a vibration at 85, so I took it to a larger shop and they found that one of my front alloy wheels was no longer round. A new one was $2,100, so the tire guy suggested he put it on the back where it would not cause vibration.

The results, after a rebalance and tire rotation, was 110 with no vibration.

The secret to this is to have a good shop do the balancing, not a place that has a balance machine that they have to dig out from under stuff to use.

The cost was less than $40, and the search is on for a place to repair the wheel.

This may not solve your problem, but a good tire guy will look at more than your tires for a vibration problem and the money you spend for their advice will save you hours of looking and wondering time.

Experts cost a lot, but that is because they are worth it.
