i Not all M+S rated tires provide special
winter performance. Make sure the tires
you use show M+S and the mountain/
snowflakeimarking on the tire
sidewall. These tires meet specific snow
traction performance requirements of the
Rubber Manufacturers Association (RMA)
and the Rubber Association of Canada
(RAC) and have been designed specifically
for use in snow conditions.
RAt the tire manufacturer’s option, any tire
with a speed capability above 149 mph
(240
km/h) can include a “ZR” in the size
designation (for example: 245/40 ZR18).
To determine the maximum speed
capability of the tire, the service
description for the tire must be referred to.
The service description is comprised of
load indexA and speed symbolB.
If your tire includes “ZR” in the size
designation and no service description is
given, the tire manufacturer must be
consulted for the maximum speed
capability.
An electronic speed limiter prevents your
vehicle from exceeding a speed of:
R130 mph (210 km/h):
-
All models except AMG vehicles
If a service description is given, the speed
capability is limited by the speed symbol in
the service description. Example:
R155 mph (250 km/h):
-
S 63 AMG
245/40
is the service description. The letter “Y”
ZR18 97Y. In this example, “97Y”
-
S 65 AMG
designates the speed rating and the speed R186 mph (300 km/h):
capability of the tire is limited to 186 mph
-
-
-
S 63 AMG (Performance Package)
(300
km/h).
S 63 AMG with increased top speed
S 65 AMG with increased top speed
RAny tire with a speed capability above
186 mph (300 km/h) must include a “ZR”
in the size designation AND the service
description must be placed in parenthesis.
Example: 275/40 ZR 18 (99Y). The “(Y)”
speed symbol in parenthesis designates
the maximum speed capability of the tire
as being above 186 mph (300 km/h).
The factory equipped tires on your vehicle
may have a tire speed rating above the
maximum speed permitted by the electronic
speed limiter.
Make sure your tires have the required tire
speed rating as specified for your vehicle in
39
or M+Sifor winter tires
