A synthetic fiber that is, per weight, stronger than steel. Used in tire construction and provides excellent high-tensile strength-to-weight.
An expression representing the height of the sidewall of a tire in terms of a percentage of tire's width.
When opposite sides of a tire's tread pattern are not identical.
A tire tread pattern made of raised rubber-compound segments.
The individual, raised rubber-compound segments making up the tread of a tire.
That portion of a tire that is the foundation for the tread, belts, bead, and sidewall.
The structure of tire cords locked around wire beads.
A finishing strip of calendered fabric used to protect the tire's bead area from the rim.
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.
The material used to fill the area above the bead between the outer and inner portion of the sidewall. Also used in enlarged form to stiffen the lower sidewall of a tire.
Circumferential channels between the tread ribs of a tire.
Loss of traction at high speeds caused by a wedge of water that lifts a tire off the road surface.
Tires designed for off-the-road and on/off-the-road use on sport/utility, small commercial, and recreational vehicles.
A method of rating a tire's load-carrying capacity (denoted by letters such as C, D, E etc.), with respect to its ply rating.
A term describing a tire with a low relative aspect ratio or series classification.
A tire sizing system using the section width (mm), aspect ratio, speed category, tire construction, and the rim diameter (inches). Example: 225/45R17.
A tire sizing system using the section width (mm), aspect ratio, type of tire construction and rim diameter (inches). Example: P215/60R16.
A layer of rubber-coated fabric or wire making up the tire casing.
A tire built with casing plies that cross the crown at an angle of 90 degrees.
Parts of a tire tread pattern created by grooves that run circumferentially around the tire.
A numerical representation of a tire's aspect ratio; for example: 50 series.
Raised rubber-compound segments on the part of the tire tread nearest the sidewall.
Slits in the tire tread. Small cuts in the surface of the tread to improve traction.
A belt material used in radial tires. Its high stiffness provides good handling and low treadwear.
The wheel(s) that direct the course of a vehicle.
Small cavities along a tire's tread designed to hold tire studs for increased traction on snow-covered surfaces.
A term representing the portion of a tire measured as its aspect ratio or series.
A tire providing the ride comfort of a passenger car tire, yet possessing high-performance tire characteristics.
The wheel(s) of a trailer unit that neither provides power nor directs the course of a vehicle.
Raised rubber-compound segments on the outside visible part of a tire.
Uniform Tire Quality Grade. A government-mandated tire rating system based on a tire's performance in treadwear durability, traction, and temperature resistance. UTQG ratings are branded on a tire's sidewall.
Variations in angles and sizes of a tire's tread elements that reduce ride noise levels.
