NFORMATION

Tire safety information will cover aspects of the

following information: Tire Markings, Tire

Identification Numbers, Tire Terminology and

Definitions, Tire Pressures, and Tire Loading.

Tire Markings

Tire Markings

NOTE:



P (Passenger) — Metric tire sizing is based on US

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 Euro

-

pean design standards. Tires designed to this

standard have the tire size molded into the side

-

wall beginning with the section width. The letter

"P" is absent from this tire size designation.

Example: 215/65R15 96H.



LT (Light Truck) — Metric tire sizing is based on

US design standards. The size designation for

LT-Metric tires is the same as for P-Metric tires

except for the letters “LT” that are molded into

the sidewall preceding the size designation.

Example: LT235/85R16.



Temporary spare tires are designed for tempo

-

rary emergency use only. Temporary high pres

-

sure compact spare tires have the letter “T” or

“S” molded into the sidewall preceding the size

designation. Example: T145/80D18 103M.



High flotation tire sizing is based on US design

standards and it begins with the tire diameter

molded into the sidewall. Example: 31x10.5

R15 LT.

P = Passenger car tire size based on US design standards, or
". blank. " = Passenger car tire based on European design standards, or
LT = Light truck tire based on US design standards, or
T or S = Temporary spare tire or
31 = Overall diameter in inches (in)
215, 235, 145 = Section width in millimeters (mm)
65, 85, 80 = Aspect ratio in percent (%)



Ratio of section height to section width of tire, or

10.5 = Section width in inches (in)
R = Construction code



"R" means radial construction, or



"D" means diagonal or bias construction

15, 16, 18 = Rim diameter in inches (in)

SERVICING AND MAINTENANCE

Service Description:
95 = Load Index



A numerical code associated with the maximum load a tire can carry

H = Speed Symbol



A symbol indicating the range of speeds at which a tire can carry a load corresponding to its load index under certain operating conditions



The maximum speed corresponding to the speed symbol should only be achieved under specified operating conditions (i.e., tire pressure, vehicle loading,

road conditions, and posted speed limits)

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

EXAMPLE:

SERVICING AND MAINTENANCE

377

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 US 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

Tire Terminology And Definitions

Term

Definition

B-pillar

The vehicle B-pillar is the structural member of the body located behind the

front door.

Cold Tire Inflation Pressure

Cold tire inflation pressure is defined as the tire pressure after the vehicle has

not been driven for at least three hours, or driven less than 1 mile (1.6 km)

after sitting for a minimum of three hours. Inflation pressure is measured in

units of psi (pounds per square inch) or kPa (kilopascals).

Maximum Inflation Pressure

The maximum inflation pressure is the maximum permissible cold tire

inflation pressure for this tire. The maximum inflation pressure is molded into

the sidewall.

Recommended Cold Tire Inflation Pressure

Vehicle manufacturer's recommended cold tire inflation pressure as shown

on the tire placard.

Tire Placard

A label permanently attached to the vehicle describing the vehicle’s loading

capacity, the original equipment tire sizes and the recommended cold tire

inflation pressures.

SERVICING AND MAINTENANCE

379

Tire Loading And Tire Pressure

NOTE:

The proper cold tire inflation pressure is listed on

the driver’s side B-pillar or the rear edge of the

driver's side door.
Check the inflation pressure of each tire, including

the spare tire (if equipped), at least monthly and

inflate to the recommended pressure for your

vehicle.

Example Tire Placard Location (Door)

Example Tire Placard Location (B-pillar)

Tire And Loading Information Placard

Tire And Loading Information Placard

This placard tells you important information about

the:
1. Number of people that can be carried in the

vehicle.

2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the front, rear,

and spare tires.

Loading

The vehicle maximum load on the tire must not

exceed the load carrying capacity of the tire on your

vehicle. You will not exceed the tire's load carrying

capacity if you adhere to the loading conditions,

tire size, and cold tire inflation pressures specified

on the Tire And Loading Information Placard in

Ú

page 184.

NOTE:

Under a maximum loaded vehicle condition, Gross

Axle Weight Rating (GAWR) for the front and rear

axles must not be exceeded.
For further information on GAWR, vehicle loading,

and trailer towing, refer
