264 Tire labeling 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 260). For further information on the load bearing index, see Load index (Y page 265). Speed index: speed index B specifies the approved maximum speed of the tire. Summer tires Index ZR...(..Y) ZR Speed rating above 186 mph (300 km/h) above 149 mph (240 km/h) ROptionally, G Warning Wheels and tires 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. Summer tires Index Q R S T H V W Y ZR...Y Speed rating Up to 100 mph (160 km/h) Up to 106 mph (170 km/h) Up to 112 mph (180 km/h) Up to 118 mph (190 km/h) Up to 130 mph (210 km/h) Up to 149 mph (240 km/h) Up to 168 mph (270 km/h) Up to 186 mph (300 km/h) Up to 186 mph (300 km/h) tires with a maximum speed rating of more than 149 mph (240 km/h) may have "ZR" in the size description depending on the manufacturer (e.g. 245/40 ZR 18). The service specification is made up of load bearing index A and speed index B. RIf the size description of your tire includes "ZR" and there are no service specifications, ask the tire manufacturer in order to find out the maximum speed. If a service specification is available, the maximum speed is limited according to the speed index in the service specification. Example: 245/40 ZR 18 97 Y. In this example, "97 Y" is the service specification. The letter "Y" represents the speed index and the maximum speed of the tire is limited to 186 mph (300 km/h). REvery tire that has a maximum speed rating of more than 186 mph (300 km/h) must have "ZR" in the size description and the service specification must be given in brackets. Example: 275/40 ZR 18 (99 Y). The speed index "(Y)" shows that the maximum speed of the tire is above 186 mph (300 km/h). Ask the tire manufacturer to find out the maximum speed. All-weather tires and winter tires Index Q M+S21 Speed rating up to 100 mph (160 km/h) up to 118 mph (190 km/h) T M+S21 21 or M+Si for winter tires.

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 (

page 260).

For further information on the load bearing

index, see Load index (

page 265).

Speed index:

speed index

specifies the

approved maximum speed of the tire.

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.

Optionally, tires with a maximum speed

rating of more than 149 mph (240 km/h)

may have "ZR" in the size description

depending on the manufacturer (e.g.

245/40 ZR 18).

The service specification is made up of load

bearing index

and speed index

If the size description of your tire includes

"ZR" and there are no service

specifications, ask the tire manufacturer in

order to find out the maximum speed.

If a service specification is available, the

maximum speed is limited according to the

speed index in the service specification.

Example: 245/40 ZR 18 97 Y. In this

example, "97 Y" is the service specification.

The letter "Y" represents the speed index

and the maximum speed of the tire is

limited to 186 mph (300 km/h).

Every tire that has a maximum speed rating

of more than 186 mph (300 km/h) must

have "ZR" in the size description

and

the

service specification must be given in

brackets. Example: 275/40 ZR 18 (99 Y).

The speed index "(Y)" shows that the

maximum speed of the tire is above

186 mph (300 km/h). Ask the tire

manufacturer to find out the maximum

speed.
