Motorcycle tires are oftentimes misunderstood. This is a
saddening fact. They must be well-taken care of because they affect
comfort, safety, handling as well as the entire ride.
We riders must be aware of the two types of tire construction – the
bias-ply and the radial. Cruisers, usually use bias-ply tires. On
the other hand, sport bikes use radials. Bias-ply has a round
profile and high sidewalls while a radial tire has a flatter profile
and shorter sidewalls.
In bias-ply, the carcass is made up of overlapping layers of nylon or
rayon cords. The flexing action generates heat to result to a good grip.
The disadvantage though of this construction is that it decreases
performance and accelerates tire wear when too much heat is generated.
Radial tire construction, however, got its name because its plies are
running at a 90-degree angle. As oppose to the bias-ply, this
construction reduces heat generation. As a result, tires are cooler. The
adverse effect though is that the sidewalls are easily flexed. Thus, the
sidewalls are given a shorter profile. Tire pressure really matters to
the tires. Therefore, it has to be checked regularly.
Aside from tire construction, we must also be knowledgeable about tire
wear in relation to choosing tires. Softer compounds are good in
producing more traction however, they wear out quickly. Harder compounds
have better wear but they may not cause a good grip. Moreover, OEM or
aftermarket motorcycle parts manufacturers and distributors must
consider dealing with effective grip coupled with longer mileage when it
comes to tires. This is of course to prolong the life of motorcycle
tires.
One factor that can affect tire wear is the rider’s riding style.
Aggressive riders usually have their front tire to wear out faster than
the rear. This is because they tend to brake late with mostly the front
brake. In contrast, cruiser riders, normally wear out the rear tire
first. The reason is that they have more weight at the back of the bike.
In order to know, when to change your tires, you can do the motorcycle tire ‘penny
test’. To do this, put a penny into a tire groove with its head pointing
down if you can see the top of the head of the person in the coin, well,
its time to change tires. It can be an indication that the tread depth
has already reached 1/32 of an inch. Remember, new tires will have a
very different contact patch and lean-over edge.
Have a feel of your new tires. Yield a better and optimum road grip and
find your edge in the riding community!
