Here are some of the common wear problems in motorcycle tires.
As with any type of vehicle's tires, motorcycle tires wear down and eventually need to be replaced. Tires which are balding are not only ineffective, they're also dangerous.
There are different types of wear for motorcycle tires. One common wear problem is the left side of front tires wearing down quickly. This can happen because of the way you lean your motorcycle while riding. Your tire wants to go straight, but you are forcing your tire to turn, causing it to wear down.
The center of a front motorcycle tire would wear down if given the chance, but this doesn't happen as quickly as with the sides. This is because the front tire does more "rolling" than "driving," meaning there is less resistance on the center of the tire than on the sides or the rear tire.
Your rear motorcycle tire will wear out in the center rather quickly, but this isn't always as noticeable as side tire wear on your front tire. One reason for this is that there's very little resistance when you're driving your motorcycle on a straight road. Provided your motorcycle tires are properly inflated, you won't have excessive wear and tear.
The center part of rear motorcycle tires tends to wear out more quickly than the sides or the front tire, primarily because of braking. When you brake, you create a lot of resistance for your motorcycle tires to deal with. Other things that may cause excessive wear on your rear center motorcycle tire are accelerating and shifting gears. With shifting gears, drive shaft bikes tend to wear tires more quickly than belt and chain drives.
Check your motorcycle tires every so often to make sure that they're still in good condition. Tires that are worn down can be slippery and cause you to slide and possibly crash. Make sure to replace your motorcycle tires when necessary.
