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

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.

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

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.
