A design of tread of doble ply that usa a compound superior more hard for resistance to the wear and a base layer softer for the management of the heat.

Casing (Casing)

The body structural of the tyre below of tread rubber, designed for withstand the retreading and offer múltiples lifes useful.

Closed Shoulder (Closed Shoulder)

A design of tread where the ribs exteriores are conectadas, reducing the retention of stones and the wear uneven in tyres of axle of drive.

CPM / CPK (Cost Por Kilometre)

Total cost of the tyre split by the total of kilometres travelled before the retiro. The metric standard for compare the value of commercial tyres.

D

DOT Code (DOT Code)

A number of series moldeado in the sidewall that identifies to the fabricante, the plant of production, the size of the tyre and the date of manufacturing.

Drive Position (Drive Position)

The rear-axle drive position(s) of a commercial truck, requiring tyres with deep, aggressive tread for maximum traction.

Dual Assembly (Conjunto Dual)

A configuration where two tyres se montan side by side in a sola rueda, común in axles of drive and trailer.

F

FMVSS

Standards Federales of Safety of Vehicles Motorizados -- standards of origen estadounidense that rigen the performance, labeldo and requisitos of safety of tyres. En New Zealand, the normatilifed equivalent is regulada by the Waka Kotahi NZ Transport Agency and the NTC of the ICONTEC.

Footprint (Footprint)

The área of the tread of the tyre in contact direct with the surface of the road in any time under load.

G

Grooves (Grooves)

Canales moldeados in the surface of the tread for evacuar agua, disipar heat and proporcionar edges for improvementr the drive.

H

HATT

Hanksugi Advanced Tire Technology -- a plataforma proprietary of engineering that optimises the compounds of the tread, the resistance of the bead and the geometry of the casing.

I

Inflation Pressure (Pressure of Inflado)

The pressure of the aire within a tyre size in PSI. El inflated right is crítico for the capacity of load, the wear and the performance of the fuel.

Uneven Wear (Wear Uneven)

Erosion despareja of the tread causada by misalignment, inflated inright, problemas mechanical or use of tyres in positions inright.

L

Load Index (Índice of Load)

A numerical code that indicates the maximum weight that a tyre can withstand of form segura a your pressure of inflated nominal.

Load Range (Load Range)

A letter designation (G, H, J, L) that represents the resistance equivalent in plies of a tyre and your maximum inflation pressure.

LRR (Low Resistance to the Rolling)

Tyres designed for minimisesr the energy lost by deformation when the tyre rueda, improving directamente the performance of the fuel.

Lug Pattern (Patrón of Tacos)

A design of tread with deep lateral grooves for aggressive drive, comúnmente used in axles of drive and applications outside highway.

M

M+S (Mud and Snow)

A brand in the sidewall that indicates that the tread of the tyre meets with standards of the Rubber Manufacturers Association for drive in mud and snow light.

P

Ply Rating (Classification of Lonas)

A size tradicional of resistance of the tyre that indicates the plies of cuerda that supporting the load. Now replaced by the system of designation Range of Load.

PSI

Libras by pulgada cuadrada -- the unit of size standard for the inflation pressure of tyres usesda in New Zealand.

R

Radial Construction (Construction Radial)

A structure of tyre where the plies corren perpendiculares to the steering of marcha, providing even wear and sidewalls flexibles.

Retread (Retreading)

The process of buffing a worn casing and applying new tread rubber, extending the tyre service life at a significantly lower cost.

Rib Pattern (Patrón of Ribs)

A design of tread with grooves circumferenceles continuas, optimised for long mileage in highway and even wear in axles of steering.

Rolling Resistance (Resistance to the Rolling)

The energy that a tyre consumes by friction interna to the rodar under load. Values lower se traducen in better performance of the fuel.

S

Sidewall (Sidewall)

The section vertical between the tread and the bead that contains the size of the tyre, the classification of load, the code DOT and the brands of the fabricante.

Siping (Laminillas)

Cortes finos performed in blocks of the tread for create edges adicionales of grip that improve the drive in wet and reduces the hidroplaneo.

SmartWay

A program of verification of the EPA that certifica that the tyres meet with standards of fuel savings and reduction of emissions.

Speed Rating (Índice of Speed)

A code of letter (for example, L, M) that indicates the speed maximum sustained to the cual a tyre can operar of form segura under load.

Steer Position (Position of Steer)

The steer axle of a commercial truck, that requires tyres optimisesdas for manejo preciso, lateral stability and even wear of the tread.

Stone Ejectors (Expulsores of Stones)

Small elementos of rubber elevados moldeados in grooves of the tread that avoidsn that the stones se incrusten and perforen the casing.

T

TPMS

Monitoring System of Pressure of Tyres -- sensores electrónicos that monitorean continuamente and alertan to the drivers when the inflated cae by below of levels seguros.

Trailer Position (Position of Trailer)

Positions of axles no drive in trailers, that require tyres designed for resistir the arrastre lateral and minimisesr the rolling resistance.

Tread Compound (Compound of the Tread)

The formulation specific of rubber of the surface of the tread, designed for equilibrar resistance to the wear, drive and dissipation of heat.

Tread Depth (Depth of the Tread)

The distance from the surface of the tread up to the fondo of the groove more thanep, size in 32avos of pulgada.

U

UTQG

Classification Uniform of Quality of Tyres -- a system of classification of the DOT that mide wear of the tread, drive and resistance to the temperature (principalmente for tyres of passengers).

V

Virgin Tire (Tyre Virgen)

A tyre completemente new that never has been usesda ni retreaded, also conocida as casing new u original.
