—Tire symbols (Compact

spare tire)

This illustration indicates typical tire

symbols.

1. “TEMPORARY USE ONLY”—A

compact spare tire is identified by

the phrase “TEMPORARY USE

ONLY” molded into its sidewall.

This tire is designed for temporary

emergency use only. For details,

see “Compact spare tire” on page

145.

2. Tire size—For details, see “Tire

size” on page 112.

3. DOT and Tire Identification

Number (TIN)—For details, see

“DOT and Tire Identification Num-

ber (TIN)” on page 111.

SU21028

4. Location of tread wear indica-

tors—For details, see “Checking

and replacing tires” on page 194.

5. Load limit at maximum cold tire

inflation pressure—For details,

see “Checking and replacing tires”

on page 194.

Number (TIN)

6. Maximum cold tire inflation

pressure—This means the pres-

sure to which a tire may be in-

flated. For recommended cold tire

inflation pressure, see “Tires” on

page 217.

7. Tire ply composition and mate-

rials—Plies mean a layer of rub-

ber−coated parallel cords. Cords

mean the strands forming the plies

in the tire.

The “DOT” symbol certifies that the

tire conforms to applicable Federal

Motor Vehicle Safety Standards.

SU21021b

8. “TUBELESS”

or

“TUBE

TYPE”—A tubeless tire does not

have a tube inside the tire and air

is directly filled in the tire. A tube

type tire has a tube inside the tire

and the tube maintains the air

pressure.

This illustration indicates typical DOT

and Tire Identification Number (TIN).

1. “DOT” symbol

2. Tire Identification Number (TIN)

3. Tire manufacturer’s identification

mark

4. Tire size code

5. Manufacturer’s optional tire type

code

9. Radial tires or bias−ply tires—A

radial tire has “RADIAL” on the

sidewall. A tire not marked with

“RADIAL” is a bias−ply tire.

—Uniform tire quality grading

This information has been prepared

in accordance with regulations issued

by the National Highway Traffic Safe-

ty Administration of the U.S. Depart-

ment of Transportation. It provides

the purchasers and/or prospective

purchasers of Toyota vehicles with in-

formation on uniform tire quality grad-

ing.

Tread wear—The tread wear grade

is a comparative rating based on the

wear rate of the tire when tested un-

der controlled conditions on a speci-

fied government test course. For ex-

ample, a tire graded 150 would wear

one and a half (1−1/2) times as well

on the government course as a tire

graded 100. The relative performance

of tires depends upon the actual

conditions of their use, however, and

may depart significantly from the

norm due to variations in driving hab-

its, service practices and differences

in road characteristics and climate.

Traction AA, A, B, C—The traction

grades, from highest to lowest, are

AA, A, B, and C, and they represent

the tire’s ability to stop on wet pave-

ment as measured under controlled

conditions on specified government

test surfaces of asphalt and concrete.

A tire marked C may have poor trac-

tion performance.

Warning: The traction grade assigned

to this tire is based on braking

(straight ahead) traction tests and

does not include cornering (turning)

traction.

Your Toyota dealer will help answer

any questions you may have as you

read this information.

DOT quality grades—All passenger

vehicle tires must conform to Fed-

eral Safety Requirements in addi-

tion to these grades. Quality

grades can be found where appli-

cable on the tire sidewall between

tread shoulder and maximum sec-

tion width. For example: Treadwear

200 Traction AA Temperature A.

Temperature A, B, C—The tempera-

ture grades are A (the highest), B,

and C, representing the tire’s resis-

tance to the generation of heat and

its ability to dissipate heat when

tested under controlled conditions on

a specified indoor laboratory test

wheel. Sustained high temperature

can cause the material of the tire to

degenerate and reduce tire life, and

excessive temperature can lead to

sudden tire failure. The grade C cor-

responds to a level of performance

which all passenger car tires must

meet under the Federal Motor Vehicle

Safety Standard No. 109. Grades B

and A represent higher levels of per-

formance on the laboratory test wheel

than the minimum required by law.

Warning: The temperature grades for

this tire are established for a tire that

is properly inflated and not over-

loaded. Excessive speed, underinfla-

tion, or excessive loading, either sep-

arately or in combination, can cause

heat buildup and possible tire failure.
