NITTO TIRE
171
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

and Replacement Tires manufactured with Pirelli Run Flat or
PNCS technology.
If a Run Flat or PNCS tire becomes unserviceable due to road hazard
damage within the first year from the date of purchase, or within the
first 2/32” of the original usable tread, whichever occurs first, the Pirelli
tire will be replaced with an identical or comparable tire at no charge \
for the tire to the owner, including mounting and balancing (subject to
applicable limitations).
What Is Not Covered by this Limited Warranty?
• Ride-related claims after the first year of purchase, or after the
first 2/32” of useable tread, whichever comes first. These include,
without limitation, uneven wear due to misalignment, worn
suspension components, mechanical interference and/or improper
inflation, flat spots due to improper transport, improper storage
and/or braking, road irregularities, etc.
•
Irregular wear.
•
Excessive noise emissions.
•
Tires with 2/32” or less tread remaining.
•
Tire damage and surface cracks due to use in low ambient
temperatures (except in winter and all-season Pirelli tires as
defined in the applicable Pirelli Product Catalog).
•
Tire damage due to abuse or misuse, including without limitation:
- improper mounting/dismounting practices, application of
aftermarket wheel protection hardware, abuse, misuse,
or neglect;
- misapplication, including improper fitment, insufficient Speed
Rating, or Load Index, or undersized or oversized tires;
-improper repair, repair not conforming to U.S. Tire
Manufacturers Association standards, or repairs with a self-
vulcanizing plug only or patch only;
- modification by the addition or removal of material or alteration
to change the appearance or performance of the tire;
-recapping, retreading, regrooving or in the studding process;
- tire operation in excess of tire/wheel manufacturers’
specifications and recommendations, including spinning;

On all wheel drive or four wheel drive vehicles the tires must always
be replaced in sets of four. When replacing tires, you should always
follow the vehicle manufacturer’s recommendations. Passenger and
light truck tires are not interchangeable, due to differences in their
pressures and load carrying capacity.
P-Metric and Euro-Metric Interchangeability: Euro-Metric (Example:
225/45R17) tires have a load index which is equal to or greater than
that of the same size P-Metric (Example: P225/45R17) tire. Therefore,
they have the same or higher load carrying capacity at the maximum
rated inflation pressure. Always check with your tire dealer or Pirelli
Tire Consumer Affairs to check interchangeability to maintain proper
vehicle dynamics.
Please be aware that it is important, before fitting the suggested tires,
to confirm that the fitment is allowed by the technical specifications of
the vehicle, the vehicle manufacturer and the relevant homologations.
Pirelli does not express any view as to the compatibility of the wheel/
tire combination with the technical specifications for the chassis
and vehicle.
TO MAINTAIN VEHICLE DYNAMICS AND LOAD CARRYING
CAPACITY, REPLACEMENT TIRES MUST ALWAYS HAVE A LOAD
INDEX AND SPEED SYMBOL EQUAL TO OR GREATER THAN
THOSE FITTED AS ORIGINAL EQUIPMENT.
When installing plus size fitments, you should consult with the dealer
regarding any suspension or braking system modifications which may
be recommended for the vehicle.
Tire Inspection
As a minimum, tires should be examined and air pressure checked
monthly and always prior to long trips. They should also be examined
if you strike any unusual object on the road. Tires showing bulges,
cracks, cuts, penetrations or uneven wear must be dismounted and
examined by an authorized Pirelli dealer and replaced if necessary.
Pirelli tires have treadwear indicators in the tread grooves, which
clearly show when the tread has worn to 2/32” remaining. At this point,
your tires must be replaced because they do not meet the federal
TOYO TIRE

WHAT IS NOT COVERED?
This Limited Warranty does not cover the following categories
of claims:
Rapid Treadwear: Original equipment tires are not guaranteed to last a
specified number of miles.
Damage from road hazards (not limited to cuts, snags, bruises, impact
breaks, bulges, punctures, stone drills, chips, and scales), fire, theft,
or collision.
Conditions arising from improper tire/vehicle maintenance or use, not
limited to:
•
Irregular or excessive treadwear due to: Incorrect inflation;
overloading; vehicle misalignment; failure to rotate tires; and poor
or defective mechanical condition of brakes, shocks, and wheels;
or other factors attributable to the vehicle or wheel.
•
Any tire which has been run with low air pressure or while flat.
•
Damage due to abuse; vandalism; tire alteration; tire spinning;
racing; or other competitive activities.
•
Damage, corrosion, or deterioration from using oil-based
chemicals, water-based sealers, balancing substances, or
flammable gases.
•
Damage from improper use of tire chains.
Tires with the DOT identification number removed or rendered illegible.
Improper mounting, balancing or repair, not limited to: •
Improper tire mounting, or tire/wheel assembly imbalance.
•
Damage from incorrect mounting or dismounting of the tire,
incorrect wheel size, water or other material trapped inside the tire
during mounting, or failure to keep the tires balanced.
•
Damage resulting from improper repair materials or procedures.
TOYO TIRE

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:
TOYO TIRE
223
• Proper spacing between dual tires is necessary for optimum tire
performance. If chains are used, particular care must be taken
to assure adequate clearance between loaded tires to avoid
damage from the chains. The allowable outside diameter
difference between a tire and its dual mate is 1/4” (6.4 mm) for
light truck tires.
Considerations in Plus Sizing
Always refer to and follow the vehicle manufacturer’s replacement
tire recommendations. In some cases, a vehicle manufacturer may
specifically advise against the application of replacement tires that are
not of the original size or type.
TIRE AND WHEEL MATCHING AND MOUNTING
TOYO TIRE
225
• Match tire size designations in pairs on an axle, except during the
temporary use of a spare tire.
•
If two radial tires and two non-radial tires are used on a vehicle, put
the radials on the rear axle. If radial and non-radial tires are used
on a vehicle equipped with dual rear tires, the radial tires may be
used on either axle.
SPEED-RATED TIRES •
If the vehicle Tire Information Placard and/or the vehicle Owner’s
Manual specifies speed-rated tires, the replacement tires must
have the same or higher speed rating to maintain vehicle speed
capability.
•
If a replacement tire has a lower speed capability than that
specified by the vehicle manufacturer, the vehicle’s speed must
be restricted to that of the replacement tire. Vehicle handling
could also be affected. Consult the vehicle Owner’s Manual or tire
manufacturer for recommendations.
•
If tires with different speed ratings are used, it is recommended
that the lower-speed-rated tires always be placed on the front axle.
This is to prevent a potential oversteer condition.
FOUR-WHEEL DRIVE (4WD) AND ALL-WHEEL DRIVE
(AWD) VEHICLES
If no instructions for tire mixing appear in the vehicle Owner’s Manual,
follow these guidelines: •
Do not mix tire sizes. All four tires must be marked with the same
tire size, unless otherwise specified by the vehicle manufacturer .
This also applies to winter/snow tires.
•
Do not mix tread pattern types such as all-terrain and all-season.
STUDLESS WINTER/SNOW TIRES •
It is always preferable to apply winter/snow tires to all wheel
positions, including dual tires, to maintain vehicle mobility
and control.
•
If winter/snow tires are applied to the front axle of any vehicle,
winter/snow tires must also be installed on the rear axle. DO NOT
apply winter/snow tires only to the front axle. This applies to all
TOYO TIRE
227
REPLACING TWO TIRES•
When a pair of replacement tires is selected in the same size and
construction as those on the vehicle, the two newer tires must be
installed on the rear axle and must be of equal or higher speed
rating than the front tires. Generally, new tires with deeper tread
will provide better grip and evacuate water more effectively, which
is important as a driver approaches hydroplaning situations.
Placing greater traction on the rear axle on wet surfaces is
necessary to prevent a possible oversteer condition and loss of
vehicle stability.
•
When two new tires have been installed onto the rear axle
positions, they are to be kept on the rear but rotated from side
to side. This is recommended after installing two new tires to the
rear position, or if you discover significant tread depth differences
between the front and rear positions during rotation intervals.
REPLACING ONE TIRE •
Replacing a single tire on a vehicle can have an adverse effect on
suspension systems, gear ratios, transmission, and tire treadwear.
•
If single tire replacement is unavoidable, it is recommended that
the single new tire be paired with the tire that has the deepest
tread and both be placed on the rear axle. Placing greater traction
on the rear axle on wet surfaces is necessary to prevent a possible
oversteer condition and loss of vehicle stability.
WHEEL ALIGNMENT AND BALANCING •
Proper wheel alignment and balance are very important
considerations for safety and getting the maximum mileage from
your tires. You need to check how your tires are wearing at least
once a month.
