TIRES
Tire Safety Information
Tire safety information will cover aspects of the following information:
Tire Markings, Tire Identification Numbers, Tire Terminology and Defi-
nitions, Tire Pressures, and Tire Loading.
Tire Markings
NOTE:
•P (Passenger) — Metric tire sizing is based on U.S. design standards.
P-Metric tires have the letter “P” molded into the sidewall preceding
the size designation. Example: P215/65R15 95H.
•European — Metric tire sizing is based on European design standards.
Tires designed to this standard have the tire size molded into the
sidewall beginning with the section width. The letterPis absent from
this tire size designation. Example: 215/65R15 96H.
Tire Markings
1 — U.S. DOT Safety Standards
Code (TIN)4 — Maximum Load
2 — Size Designation 5 — Maximum Pressure

EXAMPLE:
Load Identification:
Absence of the following load identification symbols on the sidewall of the tire
indicates a Standard Load (SL) tire:
•XL= Extra load (or reinforced) tire, or
•LL= Light load tire or
•C, D, E, F, G= Load range associated with the maximum load a tire can carry
at a specified pressure
Maximum Load– Maximum load indicates the maximum load this tire is designed
to carry
Maximum Pressure– Maximum pressure indicates the maximum permissible cold
tire inflation pressure for this tire
Tire Identification Number (TIN)
The TIN may be found on one or both sides of the tire; however, the date
code may only be on one side. Tires with white sidewalls will have the
full TIN, including the date code, located on the white sidewall side of
the tire. Look for the TIN on the outboard side of black sidewall tires as
mounted on the vehicle. If the TIN is not found on the outboard side, then
you will find it on the inboard side of the tire.
EXAMPLE:
DOT MA L9 ABCD 0301
DOT= Department of Transportation
– This symbol certifies that the tire is in compliance with the U.S. Department
of Transportation tire safety standards and is approved for highway use
MA= Code representing the tire manufacturing location (two digits)
L9= Code representing the tire size (two digits)
ABCD= Code used by the tire manufacturer (one to four digits)
03= Number representing the week in which the tire was manufactured (two digits)
– 03 means the 3rd week
01= Number representing the year in which the tire was manufactured (two digits)
– 01 means the year 2001
– Prior to July 2000, tire manufacturers were only required to have one number
to represent the year in which the tire was manufactured. Example: 031 could
represent the 3rd week of 1981 or 1991 TIRES

RFT (Run-Flat Technology) Tires:In addition to the above, there are
recommendations specific to the repair of RFT tires; see “RFT Tires with
Run-Flat Technology” in this manual.
TIRE MOUNTING AND OTHER SERVICING
WARNING!
Removing and replacing tires on wheels can be dangerous.
Attempting to mount tires with improper tools or procedures may
result in a tire explosion causing serious personal injury or death.
This is only a job for a qualified tire service professional. Never
perform tire service procedures without proper training, tools, and
equipment.
This manual is not intended to provide proper training or service
procedures for tire mounting, demounting, balancing, rotation, or
repair. Please leave these tasks to qualified tire service professionals.
For your safety and that of others:
•Always stand well clear of any tire mounting operation. This is
especially important when the service operator inflates the tire. If the
tire has been improperly mounted, it may burst with explosive force
causing serious personal injury or death.
•Tires must match the width and diameter requirements of the wheels.
For example, 16 inch diameter tires must only be mounted to 16 inch
diameter wheels. Radial tires must only be mounted to wheels
approved for radial tires.
•Wheels must be free of cracks, dents, chips, and rust. Tires must be free
of bead damage, cuts, and punctures.
•Never inflate a tire beyond 40 psi (275 kPa) to seat the beads. Be
absolutely certain beads are fully seated before adjusting inflation
pressure to the level recommended for vehicle operation.
•Never put flammable substances in tire/wheel assemblies at any time.
Never put any flammable substance into a tire/wheel assembly and
attempt to ignite to seat the beads.
•Always stand well away from the work area when tires are being spin
balanced either on or off the vehicle.

WARNING!(Continued)
•Exceeding the maximum bead seating pressure of 40 psi. Be
absolutely certain beads are fully seated before adjusting the
inflation pressure to the level recommended for vehicle operation.
Never put flammable substances in the tire/wheel assemblies at any
time. Never put any flammable substance into a tire/wheel assembly
and attempt to ignite it in order to seat the beads.
TIRE MIXING
CAUTION!
Driving your vehicle with an improper mix of tire sizes,
constructions, and speed ratings can be dangerous. Your car ’s
handling characteristics can be adversely affected. You could have
an accident resulting in serious personal injury or death. Consult
your vehicle Owner ’s Manual or an authorized Toyo Tires dealer for
proper tire replacement.
•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 TIRE
•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

TIRE AND WHEEL MATCHING AND MOUNTING
WARNING!
Any attempt to mount a tire on a wheel with a different diameter
will result in an explosion of the tire/wheel assembly that could
cause severe personal injury or death.
Prior to mounting any tire, always check the wheel identification
stamp to verify the correct wheel diameter. Always check the tire
size molded onto the sidewall.
Never exceed 40 psi when seating the tire beads onto the wheel.
Always stand well clear of any tire mounting operation. This is
especially important when the service operator inflates the tire. If
the tire has been improperly mounted, it could burst with explosive
force causing serious personal injury or death.
A new valve stem must be installed on the wheel each time a
worn-out passenger or light truck tire is replaced.
Removing and replacing tires on wheels can be dangerous.
Attempting to mount tires with improper tools or procedures could
result in a tire explosion, causing serious personal injury or death.
This is a job for your authorized Nitto dealer or other qualified tire
service location only.
Serious personal injury or death can result from:
•Failure to select the proper tire and wheel. The tire must match the
width and diameter requirements of the wheel. When mounting
truck type radial tires use only wheels approved for radial tires.
•Failure to inspect both the tire and wheel. The wheel must be free
of cracks, dents, chips, and rust. The tire must be free of bead
damage, cuts, and punctures.
•Failure to follow proper procedures. For proper mounting proce-
dures, consult the Rubber Manufacturers Association’s publication
“Care and Service of Automobile and Light Truck Tires” (ref.:
www.rma.org).
•Exceeding the maximum bead seating pressure of 40 psi. Be
absolutely certain beads are fully seated before adjusting the
inflation pressure to the level recommended for vehicle operation.
Never put flammable substances in the tire/wheel assemblies at any
time. Never put any flammable substance into a tire/wheel assembly
and attempt to ignite it in order to seat the beads.
