R
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).
The service specification is made up of
load-bearing index 0083and speed rating
0084.
R 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 rating 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).
R The size description for all tires with
maximum speeds of over
186 mph (300 km/h) must include "ZR"
and the service specification must be given
in brackets. Example: 275/40 ZR 18 (99 Y). The speed index "(Y)"
indicates that the maximum speed of the
tire is over 186 mph (300 km/h). Ask the
tire manufacturer about the maximum
speed. All-weather tires and winter tires

Not all tires with the M+S marking provide
the driving characteristics of winter tires.
In addition to the M+S marking, winter tires
also have the 004Dsnowflake symbol on
the tire wall. Tires with this marking fulfill
the requirements of the Rubber
Manufacturers Association (RMA) and the
Rubber Association of Canada (RAC)
regarding snow traction, and were specially
developed for driving on snow.
The speed rating of tires mounted at the
factory may be higher than the maximum
speed that the electronic speed limiter
permits.
Make sure that your tires have the required
speed rating for your vehicle as specified in
the "Tires" section (Y page 273), e.g. if you
buy new tires.
Further information about reading tire data
can be obtained from any qualified specialist
workshop.

driving with vehicle loads that are lighter
than the maximum vehicle load can be
found in the tire pressure table on the
inside of the fuel filler flap. Check tire
pressures regularly, and only when the tires
are cold. Comply with the maintenance
recommendations of the tire manufacturer.
These are located in the vehicle document
wallet.
Further information on recommended tire
pressures as well as tire pressures for
specific driving situations, see (Y page 251).
i Notes on the vehicle equipment – always
equip the vehicle with:
R tires of the same size on a given axle
(left/right)
R with the same type of tires on all wheels
at a given time (summer tires, winter
tires)
i The following pages contain information
on approved wheel rims and tire sizes for
equipping your vehicle with winter tires.
Winter tires are not available at the factory
as standard equipment or optional extras.
If you wish to equip your vehicle with
approved winter tires, you will also require,
in certain circumstances, wheel rims of an
appropriate size, as the sizes of approved
winter tires can deviate from those of
standard tires. This is dependent on the
model and the equipment installed at the
factory.
The tires and wheel rims, as well as further
information, can be obtained at a qualified
specialist workshop. 274
