RFT (Run-Flat Technology) Tires:In addition to the above, there are

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.

pressures when the tires are cold (when the vehicle has been driven less
than one mile). If you must check inflation when the tires are hot, add
4 psi (27 kPa) to the recommended cold inflation pressure. It is difficult
to tell just by looking at radial tires whether they are underinflated.*
Furthermore, when operating a vehicle equipped with radial tires, it is
difficult to notice when a tire has gone flat or nearly flat since the “feel”
of the vehicle does not change significantly.
*Evidence of air loss or repeated underinflation always requires expert
inspection to determine the source of leakage and tire removal to
determine repairability.To avoid injury, NEVER attempt to reinflate a
tire that has been run severely underinflated. Progressive air loss may
result from punctures, cuts, curbing, impacts or partial bead unseating.
Some fitment causes for air loss are (1) incomplete bead seating, (2) bead
tearing caused by a machine tool due to insufficient lubrication or
improper adjustment. Leaking valve core or rubber valve components
should be replaced when problems are detected and whenever tires are
replaced.
Always maintain inflation pressure at the level recommended by the
vehicle manufacturer as shown on the vehicle placard, vehicle certifi-
cation label or in the vehicle owner ’s manual:
Under inflation is the leading cause of tire failure and may result in
severe cracking, component separation or “blowout.” It reduces tire load
capacity, allows excessive sidewall flexing and increases rolling resis-
tance, resulting in heat and mechanical damage. Maintaining proper
inflation pressure is the single most important thing you can do to
promote tire durability and maximize tread life.
Over inflation increases stiffness, which may deteriorate ride and gener-
ate unwanted vibration. Over inflation also increases the chances of
impact damage.
DON’T OVERLOAD YOUR VEHICLE
Check your vehicle owner ’s manual to determine the load limits.
Overloading your vehicle places stress on your tires and other critical
vehicle components. Overloading a vehicle can cause poor handling or
increased fuel consumption and may cause tire failure. Overloading your
tires can result in severe cracking, component separation or “blowout.”
Never fit your vehicle with new tires that have less load capacity than
shown on the vehicle tire placard and remember that optimum rim width

WARNING!
•Failure to install tires with adequate load capacity will result in tire
fatigue and sudden tire failure. This could lead to loss of vehicle
control, possibly resulting in personal injury or death.
• Certain vehicle performance parameters, including ride comfort
and handling, may be affected by substitute tire sizes. In some
cases, particularly for SUVs and light trucks, a failure to follow the
vehicle manufacturer ’s recommendations for tire replacement
could adversely affect the safe handling of the vehicle, possibly
resulting in a loss of vehicle control leading to personal injury or
death.
The following procedures concerning replacement tires must be fol-
lowed:
• Confirm that the load-carrying capacity is greater than or equal to the
loadcarrying 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 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 Toyo Tires 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.
