WORN TIRES

Tires that are worn more than normal and cupping, is a problem most motorcyclist deal with some time or another. Most of the time this is usually caused from low air pressure, or failing to keep the right air pressure in your tires. But his is not always the cause.
Cupping is something that is actually normal. Excessive cupping or a whole lot of wear on one side or the other isn't.
There are at least seven causes for cupping and uneven wear on the front tire besides high or low air pressure.
1- Most roads are banked away from the centerline, so if you ride straight up or vertical the side of your tire thats the closest to the middle of the road wears more.
2- Your tires flat spot or scuff when you force a speed change with them. The rear tire scuffs when you gas the motorcycle and when you brake hard and everytime you ride in a way other than straight ahead, for this reason the rear tire usually has even cupping as compared to the front which only scuffs or flat spots when you brake.
3-Alignment isn't a problem with motorcycles most of the time but it can be.
4- Carrying more weight on one side than the other whatever the load may be can cause you to ride your bike in a slight lean and cause uneven wear.
5- Having your TRAC or anti-dive set unequally can cause uneven tire wear
6- If one of your front shocks is busted you will have uneven tire wear.
7-Overusing your front brake will cause you front tire to cup excessively.
