| 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. |

| 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...

| 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.
- The width across a wheel, measured between the rims.
|
| bead seat | - The inner ledge portion of the wheel rim where the tire bead rests adjacent to the flange.
- Part of a road wheel, below the bead lip, on which the tire bead is seated.
|
| cornering force | - The lateral frictional force generated by a cornering tire, acting in opposition to the centrifugal force.

| 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.
