Warranty

10
If you see any damage to a tire or wheel, replace it with the spare
at once and visit a Michelin Tire Retailer.
Exceeding the maximum speeds shown on the following page for each
type of MICHELIN
®
tire will cause the tire to build up excessive heat which
can cause tire damage that could result in sudden tire destruction and
rapid air loss. Failure to control a vehicle when one or more tires experience
a sudden air loss can lead to an accident.
In any case, you should not exceed reasonable speeds as indicated
by the legal limits and driving conditions.
SPEED RATING SYSTEM
The speed rating of a tire indicates the speed category (or range of speeds)
at which the tire can carry a load under specified service conditions. The
speed rating system used today was developed in Europe in response to
the need to categorize
tires into standardized
speeds. A letter from A
to Z symbolizes a tire’s
certified speed rating,
ranging from 5 km/h (3
mph) to above 300 km/h
(186 mph). This rating
system (see chart on this
page) describes the top
speed for which a tire is
certified.
When this speed rating
system was originally
developed, the Unlimited
V category of over 210
km/h (130 mph) was
the top speed rating a
tire could achieve. As
manufacturers made
more tires that fit into
this category, it was
necessary to better
regulate performance at
standardized speeds to
help ensure safety. The Limited V category of 240 km/h (149 mph) was
then created, and the Z or (Y) speed rating was added as the top speed
rating that a tire could achieve. W and Y limited speed symbols have been
added as higher speed categories.
Always consult the tire manufacturer for the maximum speed of Unlimited
Z or (Y) tires. Speed rating is identified as a part of the tire’s sizing or service
description. Exceeding the lawful speed limit is neither recommended nor
endorsed.
In the latest attempt to standardize tire designations, all ratings except
Unlimited Z incorporate the speed symbol and load index as the tire’s
service description. For Example:
