Bought new Pirelli Cinturato P7 A/S+ from TR at the end of February and had them installed locally(at our largest tire store in the Rochester, Buffalo, Niagara Falls area) in early March. From the beginning, the tires were all out of balance. I rotated all of the tires(one side at a time) to determine which tires may be the culprit and it was all 4, IMO.
Brought the car back for a re-balance and...
...The original installer said that all 4 tires were out on the inside portion of the wheels(OOPS!) and in only 3 weeks/
I told the shop that the tires were out of balance right from the beginning on the hiwy and I had already moved all tires around the vehicle. After the rebalance, the tires were only slightly better but they were not where they should be. Still shimmying.
I found a local guy who ONLY travels(you can't go to him) and installs tire, brakes, RFB, right on his truck in your driveway. He came out to my house and did a RFB on all 4 tire(1 tire had to be turned ~1/4 turn on the wheel for a road force match/RFM). But, all is now perfect.
He claimed that the tire shop that installed my tires only did a static balance not a dynamic balance(which would have been better).
This traveling tire guy ONLY does RFB with all of his tire installations. The Hunter GPS 9700 RFB is his only balancer. You can buy your own tires or get the tires from him. He uses 4-5 different local tire distributors. He allowed me to come up into his truck while he explained everything to me(as if I were in training) while he did the RFB/RFM.
Very Cool,
