Bias tyres are used primarily for off-the-road, agricultural, and industrial vehicles. Bias tyres' construction utilizes body ply cords that extend diagonally from bead to bead, usually at angles in the range of 30 to 40 degrees, with successive plies laid at opposing angles forming a crisscross pattern to which the tread is applied. The design allows the entire tyre body to flex easily, providing the main advantage of this construction, a smooth ride on rough surfaces with stronger sidewall resisting scratch and abrasion.
Radial tyres are produced for passenger cars, light trucks, trucks, and buses. Radial tyres' construction utilizes body ply cords extending from the beads and across the tread so that the cords are laid at approximately right angles to the centerline of the tread, and parallel to each other, as well as stabilizer belts directly beneath the tread. The design offers the tyres with longer tread life, better steering control, and lower rolling resistance.
Winter tyres are designed for the extreme conditions in colder weather with snow and ice. Such tyres are widely used for passenger cars, light trucks, trucks and buses, and are optimized to drive at temperatures below 7 ℃ (45 ℉).The tread compound is usually softer than summer tyre and provides better grip on ice and snow.
Winter tyres are generally categorized into two types: studdable and studless.Studdable Tyre Studless Tyre
Vehicle tyres that have metal pins or "studs" protruding from them are called studded tyres. The tyres make driving safer because of the way the metal pins in bit into the ice and caused enough friction to prevent slipping and sliding on icy and snowy roads. Studless snow tyres are the most popular style of snow tyres. The tyres are lack of the small metal studs that poke out from the treads of studded tyres, but they are designed to have good traction performance on icy and snowy roads using special compound and do not make as much noise as studded tyres, offering better ride comfort.
All-season Tyre is a compromise between one developed for use on dry and wet roads during summer and one developed for use under winter conditions. It is designed to provide balanced dry and wet performance, as well as acceptable snow traction in regions with light winter weather. They have become ubiquitous for original fitment of vehicles and replacement market due to their convenience and their adequate performance in most situations.
Summer Tyre are designed for ultra-high performance driving in warm seasons, built for responsive handling & control in both dry and wet conditions and providing great road traction.
A run-flat tyre is a pneumatic tyre that is designed to resist the effects of deflation when punctured, to enable the vehicle to continue to be driven at reduced speeds (up to 90 km/h (55 mph), and for limited distances of up to 160 km (100 mi ), or even320 km (200 mi) depending on the type of tyre. Westlake introduces runflat tyre which run safely with no air for a limited range at a limited speed. These tyre typically feature strong, load-supporting sidewalls.
