ratio is calculated by dividing the tire width by

the tire height.

Tire code: tire code = specifies the tire type.

"R" represents radial tires. "D" represents

diagonal tires, "B" represents diagonal radial

tires.

Optionally, tires with a maximum speed of

over 149 mph (240 km/h) may have "ZR" in

the size description depending on the

manufacturer (e.g. 245/40 ZR 18).

Rim diameter: rim diameter ? is the

diameter of the bead seat, not the diameter

of the rim flange. The rim diameter is

specified in inches (in).

Load bearing index: load bearing index A

is a numerical code which specifies the

maximum load-bearing capacity of a tire.

G

Warning

The tire load rating must always be at least

half of the GAWR of your vehicle. Otherwise,

sudden tire failure may be the result which

could cause an accident and/or serious injury

to you or others.

Always replace rims and tires with rims and

tires having the same specifications

(designation, manufacturer and type) as

shown on the original part.

G

Warning

Do not overload the tires by exceeding the

specified load limit as indicated on the Tire

and Loading Information placard on the

driver's door B-pillar. Overloading the tires

can overheat them, possibly causing a

blowout. Overloading the tires can also result

in handling or steering problems, or brake

failure.

Example:

The load bearing index 91 is equivalent to a

maximum load of 1356 lbs (615 kg) that the

tire can carry. For further information on the

maximum tire load in kilograms and pounds,

see (Y page 452).

For further information on the load bearing

index, see load index (Y page 456).

Speed index: speed index B specifies the

approved maximum speed of the tire.

G

Warning

Even when permitted by law, never operate a

vehicle at speeds greater than the maximum

speed rating of the tires.

Exceeding the maximum speed for which tires

are rated can lead to sudden tire failure,

causing loss of vehicle control and possibly

resulting in an accident and/or serious

personal injury and possible death, for you

and for others.

Regardless of the speed index always observe

the speed limits. Drive carefully and adapt

your driving style to the traffic conditions.
