I have had my new tire and wheel set up balanced 3 times but still get a steering wheel shake over 55 mph, this did not happen on the OEM tires. I keep suggesting they do the Road Force Balancing, but they don't think I need it. They say it will cost me $40, told them that is fine, but they don't seem to want to do it, yet they work like crazy on the rebalance. I am not very familiar with the process, but want my Mada to ride at 85 like it does at 45 which is awesome. Any suggestions? And would the RFB fix the problem?
