■Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
■Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
■Tread Wear, Traction and Temperature Grades
● Tread wear: The tread wear grade is a comparative rating based
on the wear rate of the tire wh en tested under controlled condi-
tions on a specified government te st course. For example, a tire
graded 150 would wear one and one-half (1 1/2) times as well on
the government course as a tire graded 100.
● Traction: The traction grades, from highest to lowest are AA, A,
B, and C. The grades represent the tire’s ability to stop on wet
pavement as measured under controlled conditions on specified
government test surfaces of as phalt and concrete. A tire marked
C may have poor traction performance.
● Temperature: The temperature grades are A (the highest), B and
C, representing the tire’s resist ance to the generation of heat and
its ability to dissipate heat w hen tested under controlled condi-
tions on a specified indoor laboratory test wheel.
■Snow Tires
In some heavy snow areas, local governments may require true
snow tires, those with very deeply cut tread. These tires should only
be used in pairs or placed on all four wheels. Make sure you pur-
chase snow tires that are the same size and construction type as
the other tires on your vehicle.
■SAFETY WARNING
The following safety warning appears on the tire’s sidewall. SERI-
OUS INJURY MAY RESULT FROM: • EXPLOSION OF TIRE/RIM ASSEMBLY DUE TO IMPROPER MOUNTING-MATCH TIRE DIAMETER TO RIM DIAMETER;
NEVER EXCEED 40 psi (275 kPa) TO SEAT BEADS-ONLY
SPECIALLY TRAINED PERSONS SHOULD MOUNT TIRES.
• TIRE FAILURE DUE TO UNDE R-INFLATION/OVERLOADING/

7-7. Tire Information (U.S.A.)
Location of the Tire Label (Placard)
You will find the tire label containing tire inflation pressure by tire size
and other important inform ation on the driver’s side B-pillar or on the
edge of the driver’s door frame.
SAMPLE
On the tire label you will find th e recommended tire inflation pressure
in both kPa and psi for the tires installed as original equipment on the
vehicle. It is very important that the inflation pressure of the tires on
your vehicle is maintained at the recommended pressure. You should
check the tire pressure regularly to insure that the proper inflation
pressure is maintained. Refer to Tires on P. 558.
Tire pressures listed on the vehicle placard or tire information label indi-
cate the recommended cold tire inflation pressure, measured when the
tires are cold, after the vehicle has been parked for at least 3 hours. As
you drive, the temperature in the tire warms up, increasing the tire pres-
sure.

Customer Information and Reporting Safety Defects
When you check the air pressure, make sure the tires are cold -
meaning they are not hot from driving even a mile.
Remove the cap from the valve on one tire.
Firmly press a tire gauge onto the valve.
Add air to achieve recommended air pressure.
If you overfill the tire, release air by pushing on the metal stem in
the center of the valve. Then recheck the pressure with your tire
gauge.
Replace the valve cap.
Repeat with each tire, including the spare.
Visually inspect the tires to make sure there are no nails or other
objects embedded that could poke a hole in the tire and cause an
air leak.
Check the sidewalls to make sure there are no gouges, cuts,
bulges, cracks or other irregularities.
Some spare tires require higher inflation pressure.
WARNING
■Always check the tire inflation pressures on a regular basis accord-
ing to the recommended tire inflation pressure on the tire label and
in conjunction with the information in this owner’s manual
Driving your vehicle with under-inflated tires is dangerous.
Under-inflation is the most common c ause of failures in any kind of tire
and may result in severe cracking, tread separation or “blowout”, with
unexpected loss of vehicle control and increased risk of injury. Under-
inflation increases side wall flexing and rolling resistance, resulting in
heat buildup and internal damage to the tire. It results in unnecessary
tire stress, irregular wear, loss of control and accidents. A tire can lose
up to half of its air pressure and not appear to be flat!
It is impossible to de termine whether or not tires are properly inflated
just by looking at them.

7-7. Tire Information (U.S.A.)
●Tire Placard: A label indicating the OE tire sizes, recommended
inflation pressure, and the maximu m weight the vehicle can carry.
● Tire Identification Number (TIN): A number on the sidewall of each
tire providing information about the tire brand and manufacturing
plant, tire size, and date of manufacture.
● Inflation Pressure: A measure of the amount of air in a tire.
● kPa: Kilopascal, the metric unit for air pressure.
● psi: Pounds per square inch, the English unit for air pressure.
● B-pillar: The structural member at the side of the vehicle behind the
front door.
● Original Equipment (OE): De scribes components originally
equipped on the vehicle.
● Vehicle Load Limit: The maximum value of the combination weight
of occupants and cargo.
● Bead Area of the Tire: Area of the tire next to the rim.
● Sidewall Area of the Tire: Area between the bead area and the
tread.
● Tread Area of the Tire: Area on the perimeter of the tire that con-
tacts the road when it’s mounted on the vehicle.
● Seating capacity means the total a llowable number of vehicle occu-
pants. Seating capacity is described on the tire label.
● Production options weight is the combination weight of installed
regular production options weighing over 2.3 kilograms in excess of
the standard items which they replace, and not previously consid-
ered in the curb weight or accessory weight, including heavy duty
brakes, ride levelers, roof rack, heavy duty battery, and special trim.
● Rim is the metal support (wheel) for a tire or a tire and tube assem-
bly upon which the tire beads are seated.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear
abnormally. Here are some important maintenance points:
Inspect all tire pressure monthly (including the spare) when the tires
are cold. Maintain recommended pressures for the best ride, top han-
dling, and minimum tire wear. Use the pressures specified on the
vehicle tire information placard or tire label for optimum service.
To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Inspect the tires for uneven wear and damage. Abnormal wear is usu-
ally caused by one or a combination of the following:
• Incorrect tire pressure
• Improper wheel alignment
• Out-of-balance wheel
• Severe braking
After rotation, inflate all tire pressures to specification ( →P. 558) and
inspect the lug nu ts for tightness.

NOTICE
Rotate unidirectional tires and radial tires that have an asymmetrical
tread pattern or studs only from front to rear, not from side to side. Tire
performance will be weakened if rotated from side to side.

7-7. Tire Information (U.S.A.)
GCWR (Gross Combination Weight Rating) is the maximum allowable
weight of the vehicle - including all cargo and passengers - that the
vehicle can handle without risking damage. The GCW must never
exceed the GCWR.
WARNING
■Do not tow a trailer with this vehicle
Towing a trailer with this vehicle is dangerous because it has not been
designed to tow a trailer and doing so will affect the drive system which
could result in vehicle damage.
■Overloaded Vehicle
Overloading a vehicle is dangerous. The results of overloading can
have serious consequences in terms of passenger safety. Too much
weight on a vehicle’s suspension system can cause spring or shock
absorber failure, brake failure, handling or steering problems, irregular
tire wear, tire failure or other damage.
Overloading makes a vehicle harder to drive and control. It also
increases the distance requ ired for stopping. In cases of serious over-
loading, brakes can fail completely, particularly on steep grades. The
load a tire will carry safely is a combin ation of the size of the tire, its load
range, and corresponding inflation pressure.
Never overload the vehicle and always observe the vehicle’s weight rat-
ings from the vehicle’s Safety Cert ification and Tire and Load Informa-
tion labels.
■Never Exceed Axle Weight Rating Limits
Exceeding the Safety Certification Label axle weight rating limits is dan-
gerous and could result in death or serious injury as a result of substan-
dard vehicle handling, performanc e, engine, transmission and/or
structural damage, serious damage to the vehicle, or loss of control.
Always keep the vehicle within the axle weight rating limits.
■Never Exceed GVWR or GAWR Specifications
Exceeding the GVWR or the GAWR sp ecified on the certification label is
dangerous. Exceeding any vehicle rating limitation could result in a seri-
ous accident, injury, or damage to the vehicle.
Do not use replacement tires with lower load carrying capacities than
the originals because they may lo wer the vehicle’s GVWR and GAWR
limitations. Replacement tires with a higher limit than the originals do
not increase the GVWR and GAWR limitations. Never exceed the
GVWR or the GAWR specified on the certification label.
