capability.
If a service description is given, the speed
capability is limited by the speed symbol in
the service description. Example:
245/40 ZR18 97Y. In this example, “97Y”
is the service description. The letter “Y”
designates the speed rating and the speed
capability of the tire is limited to 186 mph
(300 km/h).
R
Any 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 rating in parenthesis designates the
maximum speed capability of the tire as
being above 186 mph (300 km/h). Consult
the tire manufacturer for the actual
maximum permissible speed of the tire.

and the Rubber Association of Canada
(RAC) and have been designed specifically
for use in snow conditions.

for example when purchasing new tires.
