Worn out is to jeans, dilapidation is to buildings, exhaustion to humans - when it comes to tires it is tire wear.
Tire wear is the actual removal of rubber from the tire due to
scuffing. The latter is the process of scrubbing of material off the
tires which results to cupping, flat band upright tire wear (common on
the rear tire) and side flat band tire wear (common on front tire).
Side tire wear also happens on both sides of the front tire and also to
a minor degree on both sides of the rear tire. The reason why tires
have side tear is because of its interaction to the pavement. Do you
still remember the Newton’s First Law of Motion? Newton said, “Every
object in a state of uniform motion tends to remain in that state of
motion unless an external force is applied to it". Thus, to make a
motorcycle turn, you must apply force because the motorcycle will
continue to run in a straight, natural inertial centrifugal force. This
force is responsible for scuffing and eventually, side wear of tires.
However, as it is pretty evident, side wear usually happens on the left
front. This is especially true in countries where driver rides on the
right side of the road. Riding right would mean greater miles on the
left side. Therefore, an increase in left side wears results.
Another tire wear is cupping. This is the scalloping where a natural
wear pattern results. This happens when the tire usually grips the road
when making turns. Scalloping is apparent on the side wear bands of a
leaned motorcycle. Simultaneous with the rotating tires is the pressure
that moves to the trailing edge creating a pattern. The scuffed
off rubber causes depression which makes it possible to produce
cupping. Complicated tread pattern also produces complicated scalloping
pattern. Another factor that contributes to scalloping is the
composition of the tire. If it is soft, it is more likely to be
affected.
Rear center tire wear is another kind. This is caused by traveling
upright miles on an exaggerated acceleration and braking. This tire
wear is common to drive shaft bikes. On the other hand, belt and shield
drives can be considered as shield to lessen the gravity of wear.
Other factors that contribute to tire wear are the following – frame
geometry of the motorcycle, changing the suspension and heavy trail.
Nevertheless, bear in mind that before you run your motorcycles, tires
must be properly inflated. Or else, the tire wear will be greatly
exaggerated.
