I had the same thing on my first set of Kumhos but it never
developed into a problem.
On the same note, my current set of K tires have me wondering if I
have a defect. Yesterday I put my third event on the tires and I
noticed an entire "new groove" dead center on the tire, for the entire
circumfrence. In some places it appears to just be a narrow line,
but upon further inspection the rubber peels back exposing a 5mm
wide groove, 3/32nds deep. In some areas the rubber that peels
back is gone leaving this new groove.
Any ideas on this one?
