Try another shop first...


I had a very similar problem. As soon as I put on my 17" winters I noticed a vibration at 55-65 that went away above and below these speeds. All was well with my 19" summer set up the morning of the switch so I knew it was tire/wheel/balance related. The shop that put on the 17's balanced them using a hunter before mounting.

After I noticed the problem, the first thing I did was to go to another tire shop and had them checked and all four wheels were out of balance. No problems since then.....I did get the original tire shop to refund my mounting and balancing money and reimburse me for the work at the second shop.

If balancing/tire pressure isn't the problem then I would look at control arms and/or sway links and then alignment.
