To avoid reducing the speed capability of the vehicle, replace a speed-
rated tire only with another tire having at least the same or higher
speed rating. Remember, the “top speed” of the “lowest rated” tire on
the car cannot be exceeded without risk of tire failure.
The letter symbols and corresponding design speeds are:
* Any tire with a speed capability above 149 mph (240 km/h) can, at the tire manufacturer’s option, include a “Z” in the size designation (e.g., 245/40ZR18). If
the load index and the speed symbol are not included, the tire manufactu\
rer must
be consulted for the maximum speed capability (P245/40ZR18 speed capability
is greater than 149 mph [240 km/h]). If a service description is included with the
size description, the speed capability is limited by the speed symbol in\
the service
description (i.e., 235/45ZR17 97W = maximum speed 168 mph [270 km/h]).
** Although no upper limit speed is specified, the indicated tires nonetheless have limited rated speed capability. Call Toyo Tires Technical Services (800) 442-8696
(Pacific Time) or (888) 444-8696 (Eastern Time) for a referral for more technical
information.

molded into the sidewall near the bead. These letters mean “Mud
and Snow.” Tires designed for use in severe snow conditions
generally have tread patterns, structure, and materials for giving
superior performance. These tires are marked with the “M&S”
designation plus a mountain/snowflake
symbol. Even the best
all-season tires will not provide acceptable levels of traction if you
drive too fast in snow or ice conditions and if you do not allow more
stopping distance on icy roads compared to dry road surfaces.
Your ability to safely maneuver your vehicle in snow or ice
conditions is considerably reduced if your tires are too worn to
provide adequate road grip.
SAFE USE OF TEMPORARY SPARE TIRES
• The temporary spare tire is designed for temporary use only. It
must not be used continuously as a standard tire. The temporary
spare tire should be returned to the trunk as soon as it is
convenient to have your standard tire repaired or replaced.
•
The temporary spare tire should not be used for speeds exceeding
50 mph.
•
Never use chains on temporary spare tires, because it could cause
damage to your vehicle.
•
When you replace the temporary tire, replace it only with the same
type of tire.
•
A full-size spare tire in your vehicle is intended for use as a spare
when needed. Please see the “Tire Rotation” section for the proper
procedures for including the same size construction and speed-
rated tire (for LT tires of the same size, type, and load rating) in the
rotation pattern. (Do not rotate a temporary spare tire.)

USEFUL TIRE INFORMATION
There is a lot of useful information molded into the sidewall of a tire.\
It shows the name of the tire, its size, if it is tubeless or tube type,\
the
maximum load and maximum inflation, and important safety warnings.
The sidewall markings on passenger and light truck tires are slightly
different.

traction is reduced during rainfall and winter road conditions. Visual tire
inspection therefore becomes more crucial as the tires wear out.
Hard Braking
You must inspect your tires after any hard braking situations or after
tires have slid on the pavement. This can cause a flat spot or other
damage to the tread of the tire.
Spinning•
Do not allow tires to spin at speeds greater than 35 mph
(56.3km/h) if vehicle becomes stuck.
•
Do not stand behind a spinning tire while attempting to push
a vehicle.
Speed and force can cause a tire to disintegrate and explode and may
cause property damage and/or personal injury.
Recommended Tire Rotation
Front and rear tires perform differently and consequently YOKOHAMA
recommends tire rotation to ensure even wear and lengthen tread life.
In the absence of the vehicle manufacturer’s instruction, YOKOHAMA
recommends that its tires be rotated every 7,500 miles (12,000 km) for
normal applications.
WARNING SERIOUS INJURY MAY RESULT FROM: •
Tire failure due to underinflation, overinflation, or overloading –
follow owner’s manual or tire placard in vehicle.
•
Explosion of the tire/rim assembly due to improper mounting –
only specially trained persons should mount tires.
THERE IS DANGER IN INSTALLING A TIRE OF ONE RIM
DIAMETER ON A RIM OF A DIFFERENT RIM DIAMETER •
Always replace a tire on a rim with another tire of exactly the same
rim diameter designation and suffix letters. For example, a 16 inch
tire goes with a 16 inch rim. Never mount a 16 inch size diameter
tire on a 16.5 inch rim.
