| camber thrust | A cornering force generated by the tire's camber. |
| speed rating | A letter designation identifying the tire's high speed durability on an indoor test wheel. refer to ece 30 european indoor wheel test standards. |
| bias-ply | A type of tire construction utilizing plies that run diagonally from one bead to the other. one ply is set on a bias in one direction, and succeeding plies are set alternately in opposing directio... |
| tread void | Areas in the tread, such as grooves and channels, that permit water to drain away from the footprint. |
| harmonic marking | Markings on wheels and tires that allow match mounting to cancel tire and wheel runout, minimizing vibration. |
| wheel alignment | Alignment |
| hydroplaning | The accumulation of water in a film under the footprint which causes a tire to lift from the road surface, losing traction. hydroplaning is affected by vehicle speed, tread pattern, and water dept... |
| mounting tires | The act of fitting tires to wheel rims. |
| slip angle | The angle between the direction in which a tire is aimed or steered and the actual direction of tire travel. |
| caster | The angle between the vehicle's steering axis and a vertical line, as viewed from the side. машина разливочная; |
| tread pattern | The arrangement of blocks, grooves, sipes, and channels designed into the tread to enhance its grip. also called the tread design. |
| compounding | - The combining of five basic ingredients: rubber, carbon black, plasticizers, curing materials, and ozone retardants to form the tread and other "rubber" components of a tire.

|
| understeer | - The condition that exists during cornering when the front of a vehicle tends to skid before the rear.
- The tendency of a vessel to turn less sharply than the helmsman intended.
|
| overinflation | The condition that exists when a tire is inflated beyond the pressure corresponding to the actual load or beyond the vehicle manufacturer's recommendation. |
| imbalance | - The condition that exists when a tire's mass is not evenly distributed around the rolling axis and centerline, causing bounce (static imbalance) or shake (dynamic imbalance).
- A stat...
squilibrio; desbalance; |
| underinflation | The condition that exists when there is not sufficient air pressure in a tire to support a specific load. this causes the tire to operate with excessive deflection and rollover. |
| overall diameter | The diameter of an unloaded, inflated tire measured from the crown on one side to the crown on the opposite side. the free radius equals one-half the overall diameter. sometimes called the outside... |
| section width | The distance between a tire's sidewalls measured at the widest part of the tire. each size of tire is measured on a specific rim width. |
| rim width | The distance between rim flanges. |
| bead seat | The inner ledge portion of the wheel rim where the tire bead rests adjacent to the flange. |
| cornering force | - The lateral frictional force generated by a cornering tire, acting in opposition to the centrifugal force.
- Краевая сила
|
| treadwear | The measure of the life of a tire tread. |
| runout | - The measure of the out of roundness of the tire causing a vibration which cannot be balanced.
- Выбег (гироскопа)

ro; водоотдача; |
| revolutions per mile | The measured number of revolutions made by a tire traveling one mile. |
| belts | - The plies of tire cords beneath the tread that determines the tire's diameter and stabilizes the tread by resisting deformation from cornering, braking, and centrifugal forces.

|
| sidewall | - The portion of the tire between the bead and the tread. it is flexible to soak up bumps yet stiff to limit tire rollover.

|
| inflation pressure | The pressure of air inside a tire which applies a tensile stress to the tire cords permitting them to carry the vehicle's load. давление в колесе.; |
| plies | The reinforcing members of a tire composed of layers of cord fabric and rubber that provide the strength to contain the air pressure needed to support a load and resist deflection. |
| hoop strength | The retention strength inherent in the belt construction of a tire that resists centrifugal force and provides dimensional stability. |
| oversteer | The situation that occurs in cornering when the rear of a vehicle tends to skid before the front. |
| liner or inner-liner | The thin layer of halobutyl rubber inside a tire that contains the inflation air, sometimes called the inner-liner. all dunlop passenger tires are manufactured with an inner-liner. |
| radial | - The tire construction utilizing plies that run radially from bead to bead under the tread. this construction requires a belt to stabilize the tread and define the tire diameter.
