Put me down for similar wear on other sizes. The 205/55/14s off our
MR2 show wear similar to what you describe, after 32 runs.
Since the MR2 is not camber challenged, and has 6 and 7 inch rims, I'm
going to have to guess the problem, if any, is your pressures. This wear
pattern on our Kumhos was reduced after dropping a few pounds of air. ( I
think, the gauge is a bit schizophrenic. )
Of course, this may all be meaningless data, since the tires certainly
weren't helped by spinning the car like a top.
