WINTER DRIVING
Tires that meet the Rubber Manufacturers Association’s (RMA) definition of
snow tires are marked M/S, M+S, or M&S. On such tires, this designation is
molded into the sidewall. Tires without this notation are not recommended
for winter driving in regions that experience winter conditions.
Although All-Season tires are designed to provide reliable performance in some
winter conditions, the use of four winter tires is recommended for optimal
performance. Tires designated for use in severe winter conditions are marked
on at least one sidewall with the letters “M” and “S” plus a pictograph of a
mountain with a snowflake on it. If such a tire needs to be temporarily
replaced with a tire not so marked, you should immediately drive at
a safe speed to a Uniroyal dealer to have the spare returned to the
trunk and replaced on your vehicle by another tire with the letters
“M” and “S” and the related pictograph.
TIRE ROTATION AND REPLACEMENT
To obtain maximum tread life, you must rotate your tires. You should rotate
your tires every 6,000 to 8,000 miles (10,000 to 12,000 km) or as specified
by your vehicle manufacturer, whichever occurs more frequently. Check
your vehicle owner’s manual for any recommendations by your vehicle
manufacturer. Monthly inspection for tire wear is recommended. Your
tires should be rotated at the first sign of irregular wear, even if it occurs
before 6,000 miles (10,000 km). This is true for all vehicles. When rotating
tires with a directional tread pattern, observe the arrows molded on the
sidewall that show the direction in which the tire should rotate. Care must
be taken to maintain the proper rotation direction. Some Tire Pressure
Monitoring Systems (TPMS) may not recognize that a tire has been moved
to a different position on your vehicle. Make certain that your TPMS system
is reset, if necessary, so as to correctly identify the location of each tire on
your vehicle. Refer to your vehicle owner’s manual or your vehicle dealer
for this information. Determine whether rotated tires require tire inflation
adjustment, because front and rear position tire pressure may vary according
to the vehicle manufacturer’s specification due to the actual load on that
wheel position. Some vehicles may have tires of different size mounted
on the front versus the rear axles, and these different tires have rotation
restrictions. Always check the vehicle owner’s manual for the proper rotation
recommendations.
FULL-SIZE SPARE
Full-size spare tires (not temporary spares) of the same size and construction
should be used in a five-tire rotation and should be inspected by a tire
professional during routine tire inspection. Always have spare tires
inspected before installation. Tires are composed of various types of rubber
compounds and other materials having performance properties essential
to the proper functioning of the tire. These component properties change
over time. Always check the inflation pressure of the full-size spare and
look for any indication of cracking or other damage immediately before
incorporating the spare into rotation. If you see any damage, or if the tire is
underinflated, do not resume driving with that tire unless you have no other
option, in which case you should drive only as slowly as is safely possible in
the traffic conditions until you can both get the spare tire properly inflated
and have it checked by a tire professional to ensure that it is safe to use.
Follow the vehicle manufacturer’s recommended pattern for rotation. If such
a recommendation is unavailable, see a qualified tire professional.
REPLACEMENT OF TWO TIRES
All four tires should be replaced at the same time. However, if only two
tires are replaced, the new ones should be put on the rear. Deeper tread
tires on the rear axle provide better handling, wet grip and evacuate water,
thereby helping to avoid oversteer and loss of vehicle stability on wet
