Never have I had a worse experience getting new tires. I swapped my stock Dunlops (18") for the winter. My car only has 9k miles on it, and even before leaving the shop I dare not mention, 3 out of 4 wheels had fresh, super deep gouges on the insides of the "spokes" of the rim all in correlation to the location of the valve stems of each wheel. Obviously the damage was denied by the shop manager who claimed he did the service (as I wiped fresh metal shavings off with my finger). Only thing i can assume is a metal tool came in very strong contact inside the spokes when the stems were removed??? After calling their HQ the farthest I've gotten is having them pay for wheel repairs. They claim there is no tool they could have used to do this which is bull**** due to the damage being located in the same spot on each wheel in relation to the stem. Does anyone have any idea what part of their failure of a process caused this or how I can prove my case so they can at least be forced to admit fault? I'll attach what I can.
