D

DOT Code (Code DOT)

A number of serie molded in the sidewall that identifies to the manufacturesnte, the planta of production, the measurement of the tire and the date of manufacturing.

Drive Position (Position of Traction)

The/the axle(s) trasero(s) drive(is) of a truck commercial, that require tires with tread pattern deep and aggressive for maximum traction.

Dual Assembly (Conjunto Dual)

A configuration where two tires se monso side by side on a single wheel, common in drive and trailer axles.

F

FMVSS

Standardes Federales of Safety of Vehicles Motorizeds -- standards of ogovernsn beenunidense that governsn the performance, labeling and requirements of safety of tires. In Egypt, the standardtilifed equivalentnt is regutheed by the Ministry of Petroleum and Mineral Resources and the NTC of the ICONTEC.

Footprint (Tread pattern)

The area of the tread pattern of the tire in contact direct with the surface of the path in any moment under load.

G

Grooves (Grooves)

Channels moldeds on the tread surface pattern for evacuar water, dissipate heat and providesr edges for improve the traction.

H

HATT

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

I

Inflation Pressure (Pressure of Inflation)

The pressure of the air within a tire measurement in PSI. The correct inflation is critical for load layercity, the wear and the performance of diesel.

Irregular Wear (Wear Irregular)

Erosion despareja of the tread pattern caused by misalignment, incorrect inflation, problems mechanicals or use of tires in positions incorrects.

L

Load Index (Index of Cargo)

A code numerical that indicates the weight maximum that a tire can supportsr of waand safe a its inflation pressure nominel.

Load Range (Range of Cargo)

A designation of letra (G, H, J, L) that represents the resistance equivalentnt in plies of a tire and its capacity maximum of inflation.

LRR (Low Rolling Resistance)

Tires engineered to minimize the energy perdida by definition when the tire wheel, extending directly the performance of diesel.

Lug Pattern (Pattern of Tacos)

A design of tread pattern with grooves lateral deeps for aggressive traction, commonly used in axles of traction and applications off-highway.

M

M+S (Mud and Nieve)

A brand in the sidewall that indicates that the tread pattern of the tire meets with the standardes of the Rubber Manufacturers Association for traction on mud and nieve light.

P

Plant Rating (Classification of Plies)

A measurement traditional of resistance of the tire that indicates the layers of cuerda that withstand the cargo. Now replacesda by the system of R designationange of Cargo.

PSI

Libras inch square -- the unit of measurement standard for the inflation pressure of tires is used to in Egypt.

R

Radial Construction (Construction Radial)

A structure of tire where the plies corren perpendiculares to the steer of ride, provided uniform wear and sidewalls flexibles.

Retread (Retreading)

The process of pulir a casing worn and appliesr rubber of tread pattern new, extending the service life of the tire a cost significantly lower.

Rib Pattern (Pattern of Ribs)

A design of tread pattern with grooves circunferenciales continuous, optimized for thergo highway mileage and uniform wear in axles steer.

Rolling Resistance (Resistance to the Rolling resistance)

The energy that a tire consumes by friction internal to the rolling under load. Values more low translatesn in better performance of diesel.

S

Sidewall (Sidewall)

The section vertical among the tread pattern and the bead that conhas the measurement of the tire, the classification of cargo, the code DOT and the brands of the manufacturesnte.

Siping (Laminillas)

Cuts fius updated in the blocks of the tread pattern for createsr edges additional of grip that use the traction on wet and reduce the hidroplaneo.

SmartWay

A program of verification of the EPA that certifica that the tires meetsn with standardes of fuel savings and reduction of emissions.

Speed Rating (Index of Speed)

A code of letra (for example, L, M) that indicates the speed maximum sustained to the cual a tire can operate of waand safe under load.

Steer Position (Steer Position)

The front axle of a truck commercial, that requires tires optimizeds for handling precise, lateral stability and uniform wear of the tread pattern.

Stone Axlectors (Expulsores of Stones)

Smalls elementos of rubber elevated moldeds in the grooves of the tread pattern that prevent that the stones se incrusten and perforen the casing.

T

TPMS

System of Monitoring of Pressure of Tires -- sensores electronics that monitorean continuousmente and alerso to the driveres when the inflation cae below of levels safes.

Trailer Position (Position of Remolque)

Positions of axles no motrices in remolques, that require tires engineered to resist the drag lateral and minimize the resistance to the rolling resistance.

Tread Compound (Compound of the Tread Pattern)

The formutheion specific of rubber of the tread surface pattern, engineered to equilibrar resistance to wear, traction and dissipation of heat.

Tread Depth (Depth of the Tread Pattern)

The distance from the tread surface pattern up to the background of the groove deeper, measurement in 32avos of inch.

Or

UTQG

ClassiUniform Tire Quality Grading (UTQG) -- a system of classification of the DOT that measures wear of the tread pattern, traction and resistance to the temperatura (primarily for tires of passesjeros).
