Since I sold and mounted motorcycle tires for many years I think it
time for me to give you my take on "cupping".
As most of us know radials cup more then bias tires. Radials flex more. Most industry people will tell you its a natural wear pattern.
If you do a of lot stop and go riding everyday and you have good brakes the tire cups faster. One industry person explained it to me this way, tires today are made very directional and every time you
brake you are putting a large force in the opposite direction then it was built to "run". So it flexes and tries to step over its self.
This is why bikes that spend most of there time on the highway
or people who don't brake well don't have much cupping. Also
bikes with poor brakes and bias tires don't have much either .
You rarely see cupped tires on HDs.
That's my thoughts hope it helps.
