USING A TIRE PRESSURE GAUGE
For accuracy, check your inflation pressure with a tire pressure gauge 
when tires are cold (for example, after being parked overnight). Driving 
heats up tires and causes an inaccurate pressure reading.
To check inflation pressure with a tire pressure gauge:1.
 Remove the tire valve cap.
2.
 Place the end of the tire pressure gauge over the valve.
3.
 Press the tire pressure gauge straight and firmly and take   
a reading.
4.
 If needed, inflate and recheck the pressure with the tire   
pressure gauge.
5.
 Replace the valve cap.
RECOMMENDATIONS FOR SAFE TIRE INFLATION •
 If you must inflate your tires when they are hot, add 4 pounds per 
square inch (4 psi) (28 kPa) above the recommended inflation 
pressure specification. Recheck the inflation pressure when the 
tires are cold and adjust to the recommended inflation pressure 
shown on the vehicle’s Tire Information Placard.
•
 Never release air or nitrogen from a hot tire in order to reach 
the recommended cold tire pressure. Normal driving causes 
tires to run hotter and inflation pressure to increase. If you 
release pressure when your tires are hot, you may dangerously 
underinflate your tires. If your tires lose more than 1 pound   
per square inch (1 psi) per month, the tire, the valve, or the   
wheel may be damaged. Consult your authorized Nitto dealer for 
an inspection.

• Over-inflation can cause the tire to be more susceptible to  
impact damage.
•
 Over-inflation or underinflation may adversely affect vehicle 
handling.
•
 Remember to check your spare tire. Consult your vehicle Owner’s 
Manual for the correct inflation pressure and use of a “temporary 
use” spare tire. The inflation pressure specified for a spare tire is 
typically different from that specified for your regular tires.
•
 Use valve caps to keep valve cores clean and clear of debris and 
to help guard against air leakage.
VEHICLES EQUIPPED WITH TIRE PRESSURE MONITORING 
SYSTEMS (TPMS)
Even if your vehicle is equipped with a tire pressure monitoring  
system, you should check your tire pressure at least once per month 
when the tires are cold (for example, after being parked overnight).   
Tire pressure warning systems are not a substitute for regular tire 
pressure maintenance.

Replacement tires for any vehicle must be of a size, load range, and
load capacity (by inflation) that is capable of supporting the same load 
as the vehicle’s originally installed (OE) tires. Avoid installing used tires 
on a vehicle. There is no way to determine what road hazards or abuse 
a previously owned tire may have incurred.
The following procedures concerning replacement tires must 
be followed:•
 Confirm that the load-carrying capacity is greater than or equal 
to the load-carrying capacity of the OE tire size at the pressure 
indicated on the vehicle Tire Information Placard.
•
 Carefully note any differences between recommendations for  
front and rear axle positions regarding the tire size and/or  
inflation pressure.
•
 The speed rating must be equal to or greater than what is specified 
by the vehicle manufacturer if the speed capability of the vehicle is 
to be maintained.
•
 Tires should be mounted on approved wheel widths. If changing 
tire sizes, check to make sure the wheel has adequate load and 
inflation pressure capacity.
•
 Body and chassis clearance must be checked on the vehicle’s 
front and rear axles.
In addition to the above, light truck tire replacements should take
into consideration the following:

TIRE WEAR – VISUAL CHECK
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.

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.
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 manufacturer’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 
Technical Services at (888) 529-8200 Pacific Time if you are not sure 
about the maximum speed rating of your tires.
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.

loss in flexibility can lead to potential cracking and other damage to 
the tire. To minimize the chances of this happening, you are advised to 
follow these instructions:1.
 Do not move or operate the car with these tires in conditions 
below 15°F (-9°C).
2.
 Avoid moving these tires in conditions below 15°F (-9°C).
3.
 Before mounting and dismounting, store these tires for at least  
24 hours in a temperature-controlled environment of 68°F (20°C) 
or warmer.
4.
 Remove these tires from the vehicle and deflate to half the normal 
air-pressure during prolonged periods of non-use or storage.
Always inspect tires for signs of cracking and never use tires that 
have cracked.
SPECIAL ADVICE FOR LIGHT TRUCKS
Never exceed the speed limit as indicated by the speed symbol on  
the tire’s sidewall. See the chart and explanation of speed ratings in 
this manual.
If you do not know the speed rating of your Nitto brand tire, contact 
your Nitto dealer or Nitto Tire U.S.A. Inc. for current information.

It is not recommended that any light truck be operated at speeds in 
excess of legal limits. However, if it is anticipated that sustained driving 
at speeds in excess of 65 mph may be required, then the following 
adjustments or recommendations should be followed:•
 At speeds from 66 mph through 75 mph, cold inflation pressure 
must be increased 10 psi above the recommended pressures for 
the load being carried.
•
 Do not exceed the maximum inflation pressure of the wheel (all 
wheels have maximum allowable inflation pressures).
Replacement Tires for Light Trucks – P-Metric vs LT-Truck
Tire installers should exercise extreme caution when replacing tires on 
light trucks.
The maximum load capacity stamped on the sidewall of a P-metric tire 
is reduced by a factor of 1.1 when used on a light truck, a sport utilit\
y 
vehicle, or a trailer.
