Main Components of Tyres

The main components of tires include the tread, which provides traction; the carcass, typically made of layers of fabric and steel belts; and the inner liner, which retains air pressure. The various components of tyres are:

Belts

Belts consist of rubber-coated layers made from materials such as rayon, steel, and fibreglass. Positioned within the tyre's midsection, they crisscross at various angles, securely holding the tyre plies in place. These belts are crucial in puncture resistance and ensuring the tyre treads maintain contact with the road surface.

Sipes

Sipes refer to specialised treads embedded within the tyre's primary tread pattern. These unique treads enhance traction on various road surfaces, improving grip and performance.

Tread

The tread is the section of the tyre that directly contacts the road. It necessitates robust strength and effective heat dissipation properties to ensure the tyre's longevity and optimal performance.

Grooves

Grooves are spaces intentionally incorporated into the tyre's outermost layer, which comes into contact with the road. These grooves serve the vital purpose of creating channels for water to disperse, reducing hydroplaning risk, and enhancing friction between the tyre and the road surface.

Shoulder

The shoulder of the tyre is located at the outer edge of the tread, extending into the sidewall region. This part of the tyre contributes to cornering stability and overall handling characteristics.

Sidewall

The sidewall constitutes the external portion of the tyre that is exposed to the environment but does not make contact with the road surface. It serves a dual purpose: protecting the internal cord plies and displaying essential information such as tyre size and type markings.

Inner Liner

Positioned as the innermost layer of tubeless tyres, the inner liner is critical in preventing the exchange of air between the tyre's interior and the external environment. This essential component helps maintain proper tyre pressure and structural integrity.
