Without knowing this was a Galant VR4, I was about to ask if you had a 3 series BMW. Would have said normal condition and don't put Kumho's on a German car. This was not the case, but certain suspensions and certain tires ...
Too bad they didn't know about the alignment procedure. Not many cars follow such a convoluted procedure such as Mitsubishi set out with for the VR4, so let's hope this is a one time issue for you. Last champion tire wear customer I had come in with 4 tires burning all inside edges, was a newer 2013?ish Lexus IS250 F. Can't wait to see her snow tires at the end of this next winter season. Yeah, I installed the snow tires with rims, in September.
