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 paren-
thesis 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.
i Not all M+S rated radial-ply tires provide
special winter performance. Make sure the
tires you use show M+S and the
mountain/snowflake . marking 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.
If your tire includes “ZR” in the size
designation and no service
description 5 and 6 (୴ page 384) is
given, the tire manufacturer must be
consulted for the maximum speed
capability.
