Dealing with Motorcycle Tire Wear
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.
