342 Definitions for tires and loading Maximum load on one tire Maximum load on one tire. This is calculated by dividing the maximum axle load of one axle by two. Weight of optional extras The combined weight of those optional extras that weigh more than the replaced standard part and more than 2.3 kilograms (5 lbs). These optional extras, such as highperformance brakes, level control, a roof rack or a high-performance battery, are not included in the unladen weight and the weight of the accessories. PSI (pounds per square inch) Standard unit of measurement for tire pressure. Aspect ratio Relationship between tire height and tire width in percent. TIN (Tire Identification Number) A unique identification number which can be used by a tire manufacturer to identify tires, for example for a product recall, and thus identify the purchasers. The TIN is made up of the manufacturer's identity code, tire size, tire type code and the manufacturing date. Tire pressure Pressure inside the tire applying an outward force to every square inch of the tire's surface. The tire pressure is specified in pounds per square inch (psi), in kilopascal (kPa) or in bar. The tire pressure should only be corrected when the tires are cold. For this, the vehicle must have been stationary for at least three hours or not have traveled more than 1.6 km (1 mile) in this time. Tires and wheels Load bearing index The load bearing index (also load index) is a code that contains the maximum load bearing capacity of a tire. Traction Traction is the result of friction between the tires and the road surface. Tire tread The part of the tire that comes into contact with the road. TWR (permissible trailer drawbar noseweight) The TWR is the maximum permissible weight that the ball coupling of the trailer tow hitch can support. Tire bead The tire bead contains steel wire which is bound by steel cords that hold the tire on the wheel rim. Wear indicator Sidewall The part of the tire between the tread and the tire bead. Narrow bars (tread wear bars) that are distributed over the tire tread. If the tire tread is level with the bars, the wear limit of 1/16 in (1.6 mm) has been reached.

Maximum load on one tire

Maximum load on one tire. This is calculated

by dividing the maximum axle load of one axle

by two.

PSI (pounds per square inch)

Standard unit of measurement for tire

pressure.

Aspect ratio

Relationship between tire height and tire

width in percent.

Tire pressure

Pressure inside the tire applying an outward

force to every square inch of the tire's

surface. The tire pressure is specified in

pounds per square inch (psi), in kilopascal

(kPa) or in bar. The tire pressure should only

be corrected when the tires are cold. For this,

the vehicle must have been stationary for at

least three hours or not have traveled more

than 1.6 km (1 mile) in this time.

Tire tread

The part of the tire that comes into contact

with the road.

Tire bead

The tire bead contains steel wire which is

bound by steel cords that hold the tire on the

wheel rim.

Sidewall

The part of the tire between the tread and the

tire bead.

Weight of optional extras

The combined weight of those optional extras

that weigh more than the replaced standard

part and more than 2.3 kilograms (5 lbs).

These optional extras, such as high-

performance brakes, level control, a roof rack

or a high-performance battery, are not

included in the unladen weight and the weight

of the accessories.

TIN (Tire Identification Number)

A unique identification number which can be

used by a tire manufacturer to identify tires,

for example for a product recall, and thus

identify the purchasers. The TIN is made up

of the manufacturer's identity code, tire size,

tire type code and the manufacturing date.

Load bearing index

The load bearing index (also load index) is a

code that contains the maximum load bearing

capacity of a tire.

Traction

Traction is the result of friction between the

tires and the road surface.

TWR (permissible trailer drawbar

noseweight)

The TWR is the maximum permissible weight

that the ball coupling of the trailer tow hitch

can support.

Wear indicator

Narrow bars (tread wear bars) that are

distributed over the tire tread. If the tire tread

is level with the bars, the wear limit of

(1.6 mm) has been reached.
