I went there to have the balance checked on a front tire. Jason told me it was pretty far out of spec and would probably need to be replaced. He said he'd try to balance it as best he could anyway, and for me to let them know after driving it on the highway if I still needed a new tire. He somehow managed to work his magic on the tire and it's much, much better. In fact, I won't need a new tire after all, but will definitely be going back to see him when I need a new set of 4. Highly recommended. Bill from Sturbridge.
