Tire cupping

Left side only wear is a pretty hot topic on Valkyries and, I believe on any bike that pushes the front end. It actually has to do with which side of the road you ride on.

As i recall the cupping seemed to be between the treads?
My Pilots dont have much for tread, but i'll have a closer look at them.
Great stuff. Thanks guys.

It actually has to do with which side of the road you ride on.

I read somewhere that wear is different on each side of the tire because left hand turns are a wider arc than right hand turns (when you drive/ride on the right side of the road). Also the left hand turns are longer in length as opposed to right hand turns, again where you normally ride on the right of the road.

I'll add a little input, something I overheard. This is not my theory, just picked up in a conversation with the guys at the local bike shop. Here in Vermont all of the roads (paved or dirt) are heavily crowned, meaning they are higher at the center than at the edges. This is done to facilitate drainage. Because the pavement is at such an angle it causes uneven wear and cupping on the left side of the tire only.
