I've always paid around $20 tops for a mount/balance from a local shop that uses the Hunter GSP 9700.
There is a company a buddy of mine recommended that he uses quite often - Euro-Tire out in Fairlawn, NJ. Asking price is $200 for a set of 4 wheels mount/balance. Man those are steep rates but I am a nut about have perfectly balance tires.
Anyone ever see rates these steep ;) Is it common of a *high-end* shop for rates as high as the one I was quote ?
