WARNING!(Continued)
Pull over to a safe area as soon as possible and inspect the tires for
signs of bulges, blisters, or separations. Seek roadside assistance or
change the damaged tire with your spare tire.
If you experience a blowout or a sudden tire failure, the following
information should be helpful:
•When the tire failure occurs, you may hear a loud noise, or feel a
vibration, and/or the vehicle may pull toward the side of the failed
tire. Do not abruptly brake or turn.
•Maintain steady pressure on the accelerator pedal.
•Hold the steering wheel firmly and steer to maintain your lane
position.
•Find a safe place to pull off the road and allow the vehicle to gradually
decelerate. Apply light braking as required to stop safely.
•Gradually pull over to the shoulder and come to a stop. Look for a
damaged tire on your vehicle.
•Seek roadside assistance or change the damaged tire with your spare
tire.
•Have all of your tires and the vehicle thoroughly inspected by a tire
professional.
TIRE ROTATION
The purpose for rotating tires is to achieve more uniform wear for all tires
on a vehicle. Your tires should be thoroughly examined on a lift by a tire
dealer for any abnormalities. If tires show uneven treadwear, ask the
service person to check and/or correct any vehicle wheel alignment or
other mechanical problem before rotation.
The following rotation patterns are acceptable. Please refer to your
vehicle Owner ’s Manual for rotation advice.
NITTO TIRE

Page 298 of 316
Full-size spare tires (not temporary spares) of the same size, construction,
and speed rating may be used in a five-tire rotation pattern.
After rotation, check the inflation pressure of all the tires. The front and
rear tire pressures may vary according to the vehicle manufacturer ’s
specifications.
Remember to follow your vehicle Owner ’s Manual for tire rotation
intervals. Your Limited Warranty recommends Nitto brand tires to be
rotated as follows:
•Every 3,500 miles or less for high performance (low profile) tires.
•
Every 7,500 miles or less for standard passenger and light truck tires.
NITTO TIRE

More frequent rotation or a thorough vehicle inspection may be necessary
if, upon inspection, irregular or erratic treadwear is beginning to appear.
It is important to remember the following:
•These tire rotation recommendations do not take into account different
tire and construction types mixed on the vehicle.
•Some tires cannot be rotated in the manner described. Such tires
include unidirectional tires. Unidirectional tread patterns must be
rotated front-to-rear only so that the direction of revolution does not
change.
•Some vehicles are designed with different tire sizes on the front and
rear axles. Normally, such combinations will not allow rotation. Prior
to rotating, consult the vehicle Owner ’s Manual.
•For vehicles with dual rear wheels, see the vehicle Owner ’s Manual for
the vehicle manufacturer ’s procedures. If your vehicle Owner ’s
Manual is not available, please contact the vehicle manufacturer.
•Some vehicles are equipped with wheels that limit the choice of
rotation pattern. Consult the vehicle Owner ’s Manual.
•Do not include temporary spare tires in the rotation pattern. However,
if your spare tire is the same size and type as a road tire (for LT tires
of the same size, type, and load rating), it should be included in the tire
rotation process. The proper procedure is to use the vehicle manufac-
turer ’s recommended tire rotation procedures, or if not available, to
use the appropriate rotation pattern shown, inserting the spare in the
right rear position. Place the tire that would have gone to the right rear
in the spare tire storage position as the new spare.
•Important! After rotation, adjust the pressure of the individual tires to
the vehicle manufacturer ’s recommendation or the inflation pressure
recommended by Nitto for an optional fitment according to the tire’s
new location on the vehicle.
•Do not mix speed-rated tires on the same axle. Higher speed-rated tires
must remain on the rear axle. Consult your authorized Nitto dealer.
TIRE SPEED RATING
All Nitto passenger and light truck tires have a maximum speed rating
based on size and type. Tires must never be operated in excess of their
rated speed limit! Consult your tire dealer or contact Nitto at
NITTO TIRE

888–529–8200 Pacific Time if you are not sure about the maximum speed
rating of your tires.
WARNING!
No tire, regardless of its design or speed rating, has an unlimited
capacity for speed. Exceeding the tire’s speed capability could cause
overheating and sudden tire failure, possibly leading to loss of
vehicle control and serious personal injury or death.
Nitto does not endorse the operation of any vehicle in an unsafe or
unlawful manner. Obey all local speed limits.
Tire speed ratings do not imply that a vehicle can be safely driven at the
speed for which the tire is rated. Speed ratings are based on laboratory
tests and relate to performance on the road, but are not applicable if tires
are underinflated, overloaded, worn out, damaged, or altered.
WARNING!
High-speed driving with underinflated or overloaded tires may
result in immediate tire failure, possibly leading to loss of vehicle
control, which could cause an accident, including serious personal
injury or death.
EXPLANATION OF TIRE SPEED SYMBOLS
A speed rating is designated by a letter that indicates the maximum
speed capability of a tire. The speed rating of a tire is based on standards
for reaching and sustaining a specified speed, and is determined via
laboratory tests that simulate road performance at various speeds.
NITTO TIRE

Tires may be marked with one of these speed symbols: M, N, P, Q, R, S,
T, U, H, V, W, Y, or (Y) to identify the particular tire’s speed rating.
Additionally, the letter Z may appear in the size designation.
When purchasing or replacing speed-rated tires, make sure to:
•Use the ranking in the following chart to compare the speed symbols
of all the tires.
•Follow the vehicle manufacturer ’s recommendations, if any, concern-
ing the use of speed-rated tires.
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:
Speed-Rated Symbol Speed Category
M Up to 81 mph (130 km/h)
N Up to 87 mph (140 km/h)
P Up to 93 mph (150 km/h)
Q Up to 99 mph (160 km/h)
R Up to 106 mph (170 km/h)
S Up to 112 mph (180 km/h)
T Up to 118 mph (190 km/h)
U Up to 124 mph (200 km/h)
H Up to 130 mph (210 km/h)
V Up to 149 mph (240 km/h)
W Up to 168 mph (270 km/h)*
Y Up to 186 mph (300 km/h)*
ZR Over 149 mph (240 km/h)**
(Y) Over 186 mph (300 km/h)**
* 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 manufacturer must be consulted for the maximum speed capa-
bility (P245/40ZR18 speed capability is greater than 149 mph
[240 km/h]). If a service description is included with the size description,

mNOTICE!
Tire speed symbols do not imply that vehicles can be safely driven at the
maximum speed for which the tire is rated, particularly under adverse road
and weather conditions, or if the vehicle has unusual characteristics. Never
operate a vehicle in an unsafe or unlawful manner.
TIRE SPINNING
WARNING!
Spinning a tire to remove a vehicle stuck in mud, snow, or wet grass
can be dangerous. This could cause serious personal injury or death to
a bystander or passenger and extensive vehicle damage. A tire
spinning at a speedometer reading above 35 miles per hour (55 km/h)
can reach a speed capable of disintegrating a tire with explosive force
within a matter of seconds. Under some conditions, a tire may be
spinning at twice the speed shown on the speedometer. Never spin a
tire above a speedometer reading of 35 mph (55 km/h). Never allow
anyone to stand near or directly behind the spinning tire. Do not spin
if a drive wheel is off the ground.
TOWING OR USE OF SLIDE-IN TRUCK CAMPERS
If you are towing a trailer or using a slide-in truck camper, refer to your
vehicle Owner ’s Manual.
WINTER (SNOW) TIRES
Winter driving presents special challenges for vehicle
handling. The use of winter tires, studs, and chains, while
improving traction performance in snow and ice, requires
additional caution and care with regard to braking, corner-
ing, and speed. It is important to drive with care not only
on snow and ice, but on dry and wet roads as well.
NITTO TIRE
301
Page 303 of 316

WARNING!
Studded tires may require longer braking distances on dry or wet
paved surfaces. Failure to allow for adequate braking distance could
result in serious personal injury or death.
•Traction is considerably reduced as snow tires approach 50% tread
wear, and replacement should be considered in order to maintain
effectiveness in heavy snow conditions.
•Tire speed rating – When lower-speed-rated winter tires replace
higher-speed-rated touring and high performance all-season radial
tires, do not exceed the lower-rated speed.
•Follow recommendations in the vehicle Owner ’s Manual for winter
tires, studs, and chains.
•Consult your tire dealer, the Rubber Manufacturers Association web-
site
www.rma.org, or your state’s Department of Transportation
(DOT) for information regarding regulatory and seasonal restrictions
for stud usage.
•Also see the “Tire Mixing” section in this manual for more details.
•Nitto recommends that snow tires be installed in matched sets of four.
ADVERSE WEATHER DRIVING
Take special care when driving in adverse weather conditions.
•Rain and snow – Driving in rain or snow considerably reduces the
traction between your tires and the road surface. You must always
reduce your speed to allow additional stopping distance between you
and the vehicles ahead of you.
•Hydroplaning and wet weather driving – Hydroplaning occurs on wet
roads and refers to the loss of tire contact with the road due to the
build-up of water between the tire contact patch and the road surface.
Three main factors affect hydroplaning and, consequently, your tire
traction on wet roads:
A. Vehicle Speed – As speed increases, wet traction is considerably
reduced.
NITTO TIRE
302
Page 304 of 316

B. Water Depth – The deeper the water, the sooner your tires will lose
traction. Even thin water layers can create sufficient lubrication to
cause traction loss at low speeds, depending on road conditions.
C. Tire Tread Depth – As your tires wear down, their decreased ability
to resist hydroplaning can result in a complete loss of traction and
vehicle control. You should always reduce your speed with con-
sideration for the traffic around you.
•Driving on ice and snow – Your all-season tires were designed to
provide higher levels of snow traction compared to non-all- season
tires. You have all-season tires if you find letters “M&S” are 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
WARNING!
The spare tire your car is equipped with may be of a different size
and construction from the other tires on your vehicle. When using
any temporary type spare tire, be sure to follow the vehicle
manufacturer ’s instructions. Failure to observe recommended
precautions could lead to erratic vehicle behavior and/or tire
damage, possibly resulting in an accident and serious personal
injury or death.
•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.
