A synthetic fiber that is, per weight, stronger than steel. Used in tyre construction and provides excellent high tensile strength to weight.
An expression representing the height of the sidewall of a tyre in terms of a percentage of tyre's width.
When opposite sides of a tyre's tread pattern are not identical.
A tyre tread pattern made of raised rubber-compound segments.
The individual, raised rubber-compound segments making up the tread of a tyre.
A condition when a tyre is bulging or crumpling.
That portion of a tyre that is the foundation for the tread, belts, bead and sidewall.
The structure of tyre cords locked around wire beads.
A finishing strip of calendered fabric used to protect the tyre's bead area from the rim.
Compound:The general term referring to the chemical formula for the tread material.
The wheel(s) that provide the power or driving force for a vehicle.
Light Truck Tyres
Tyres designed for off-the-road and on/off-the-road use on sport/utility, small commercial and recreational vehicles.
A method of rating a tyre's load-carrying capacity (denoted by letters such as B, C, D, etc.) with respect to its ply rating.
A tyre sizing system using the section width (mm), aspect ratio, speed category, tyre construction and the rim diameter (inches). Example: 185/70SR13.
A term describing a tyre with a low relative aspect ratio or series classification.
A tyre sizing system using the section width (mm), aspect ratio, type of tyre construction and rim diameter (inches). Example: P225/70R15.
Passenger Car Tyre
Automobile tyres featuring aspect ratios of 70 or greater, using a taller profile for increased ride comfort.
A layer of rubber-coated fabric or wire making up the tyre casing.
Parts of a tyre tread pattern created by grooves that run circumferentially around the tyre.
S-speed or S-performance rated
A speed category for tyres with a maximum speed capability of 180 km/h.
A numerical representation of a tyre's aspect ratio; for example, 50 series.
Raised rubber-compound segments on the part of the tyre tread nearest the sidewall
Slits in the tyre tread. Small cuts in the surface of the tread to improve traction.
A belt material used in radial tyres. Its high stiffness provides good handling and low treadwear.
The wheel(s) that direct the course of a vehicle.
Small cavities along a tyre's tread designed to hold tyre studs for increased traction on snow-covered surfaces.
Uniform Tyre Quality Grade. A government-mandated tyre rating system based on a tyre's performance in treadwear durability, traction and temperature resistance. UTQG ratings are branded on a tyre's sidewall.
V-Speed or V-Performance Rated
A speed category for tyres with a maximum speed capability of 240 km/h.
Variations in angles and sizes of a tyre's tread elements that reduce ride noise levels.
