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:

• 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 MIXING
• Toyo Tires recommends that all four tires be of the same size, 
speed rating, and construction (radial or non-radial). In some 
cases the vehicle manufacturer may require different sized tires 
for the front or rear axles. Never mix P-metric or European Metric 
passenger tires with LT-metric tires on the same vehicle.

• 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

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.

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 Toyo 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 Toyo Tires 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 Toyo 
Tires dealer.
TIRE SPEED RATING
All Toyo Tires passenger, light truck, and 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 contac\

Toyo Tires 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.
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.
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, 
concerning the use of speed-rated tires.
