Welcome into the World of Westlake
Tread, shoulder, sidewall, bead, carcass, belt, inner liner, and other components are structurally connected to complete the scientific structure of a tyre.
The tread is the part of the tyre that comes in contact with the road surface, consisting of thick rubber or rubber/composite compound formulated to provide an appropriate level of traction and increase the tyre’s driving lifespan.
Belts are calendered sheets consisting of a layer of rubber, a layer of closely spaced steel cords, and a second layer of rubber. The steel cords are oriented radially in radial tyre construction, and at opposing angles in bias tyre construction. Belts give the tyre strength and dent resistance while allowing it to remain flexible.

Undertread is a rubber layer provided for use in retreading the tyre, compounded for high heat resistance to increase high-speed durability and fuel economy and provides adhesion of tread to the tyre carcass.
Belt Edge Cushion is approximately 1-inch wide bands covering only the inner and outer edges of the steel belts and absorbs the stress of belt layer. Westlake Tyre feature a belt edge cushion to help prevent separation of the belt edges, and therefore the tread, caused by the scissoring effect of the belts.

The inner liner is an extruded halobutyl rubber sheet compounded with additives that result in low air permeability. The inner liner assures that the tyre will hold high-pressure air inside, without the air gradually diffusing through the rubber structure. The rubber layer generally consists of butyl, synthetic rubber, or polyisoprene type.
Beads are bands of high tensile-strength steel wire encased in a rubber compound. It is made up of various parts including the bead wire, core, rubber and flipper and contacts the rim on the wheel. The bead seats tightly against the two rims on the wheel to ensure that a tubeless tyre holds air without leakage.
The sidewall is located between the tyre’s shoulder and bead. It prevents air from escaping and keeps the body plies protected and provides a comfortable riding experience due to its flexibility during driving. Also, the type of tyre, size, structure, tread pattern, manufacturer, brand name, and other detailed information are marked on the sidewall.
The rim cushion compound is highly resistant to the heat brought by the heavy load or transmitted by the rim so as to extend the tyre life.
