I have 3500 miles on a pair of Z6's. The wear pattern is really strange - at least to me. The sides of the front and rear are cupping severly, the rear more so. And they also show what I think is described as flat-centering.
I have a call into Metzler, but thier Tech Rep is at Sturgis. Has not retuned my call of a week ago.
So I am asking the next best experts I know, the St-Owners. Is this a normal wear pattern? Is it normal at 3500 miles? See thumbnails. I wet tires so imperfections show up better in the pics.
I never let the tires fall below 40 PSI. I normally run 42/42 psi front and rear. The wheels are not balanced - but the cupping at every tread does not seem to be balanced related. I think the cupping would be every other tread if the wheels were out of balance.
Should I be concerned about a decreased contact patch in turns?
Any help or opinions would be appreciated. A few tire dealers and local motorcycle parts store are also bewildereed as to the root cause of this wear pattern.
