The tread blocks will show an uneven, stepped pattern to the following
portion, with the leading edge considerably higher in badly cupped
examples.  Vibration can be quite harsh and head-shaking is quite common
at about 35/45 mph if the bars are released.

I switched to Meztler Z-4's awhile back and eliminated this problem,
however it is replaced by an odd wear pattern that runs around the
circumference in band-like shapes.  This is much less vibration-inducing
than the cupping experienced with Bridgestone and Dunlop.  For obvious
reasons, this applies to fronts only.

I haven't tried either Avon (owned by Cooper Tires) or Michelin (owned
by residents of a semi-mythical country known as "France".  No relation
to the owners of Daytona.).

On reflecting that he had done nothing to help anyone all that day, the
Emperor Titus (A.D. 39-81) uttered these praiseworthy words: "Friends, I
have lost a day."

A seriously cupped front tire will look like it has scallops on either
side of the center line when viewed fromthe front.  Our Sprints tend to
cup the tires early.  Mine were noticeably cupped by 4000 miles until I
race teched the forks.
