A tire is not just another part of your motorcycle or scooter, It’s a morsel of natural rubber entrusted to offer you a smoother ride when sculpted around the rim of a motorcycles. Made up of multiple layers as per the standardized processes and needs of the two wheeler, each layer of tire has a specified role that improves its performance every time you ride your motorcycle.
So when you’re looking for new tires for your ride you often confronted by a jargon of words you have no knowledge of. So let us explain a few used in the motorcycle tire business.
The Inner Liner of the tire
Inner liner is the bottom-most layer in a tire. Built out of synthetic rubber that can resist air diffusion, the inner liner ensures to keep the air in your tires remains intact for longer period of time. The inner liner is only important for tubeless tires.
The Bead of the tire
Made up of a strong cord-like fabric such as metal wires wrapped around in a firm rubber, bead in a tire is assigned to keep the tire attached to the wheel. It plays a vital role of minimizing any air escape and also keeps the tire remain attached to the wheel even in the case of puncture as well.
The Carcass of the tire
A carcass can be tagged as a customary backbone of the tire. It is the entire inner structure that undertakes the core tire functionality. It not only upholds the air pressure, but also maintains vertical load and absorb shocks when unavoidable.
The Sidewall of the tire
Sidewall plays a important role in connecting the bead to the shoulder. It can be identified with ease as one glance at the sidewall will tell you all you require to understand about your motorcycle tire – everything from the type of tire to the manufacturer is printed on the sidewall. Easily identifiable, it is usually made of rubber and reinforced with steel chords to enhance strength and ductility to increase performance.
The Shoulder of the tire
The crucial link between sidewall and read is the should of the tire. As it is designated to diffuse heat generated within the tire, sidewall is caved out with the thickest rubber across the board.
The Breaker of the tire
Found between the carcass and the tread, the breaker is also known as the belt of the tire. In case the tread takes any penetrative damage, the breaker is empowered to protect the carcass of the tire. It performs as a damper for shocks, prevents tearing, and also curtail the separation of the carcass from rest of the tire.
The Ply of the tire
In order to avoid any unnecessary stretching of rubber when under duress, stiff cords are melded into the body of the tire to make sure it retains it shape. Called plies, and the quality and design of these cords augment the performance of the tire.
The Tread of the tire
Constructed out of rubber or a combination of rubber and composite compound, the tread is arguably the single most vital component of the tire. As it is the tire’s point of contact with the road, the tread provides traction and grip to the motorcycle. The design that you see on the tire is tread which is made up of grooves, lugs, voids and sipes. Where grooves displace water so that the motorcycle does not slide around on wet surface, sipes are little divots cut into the grooves and the shoulder to allow the displaced water to escape the tire. Lugs and voids are the crests and dips of a groove respectively – while lugs help the tire stay planted, voids being the negative space between them, allow the lugs room to flex, and this flexing motion pushes the water outwards from under the tire.
