WARNING: If the tire label shows different tire pressures for

the front and rear tires and the vehicle is equipped with TPMS

(tire pressure monitoring system), then the TPMS sensors need to be

reset after tire rotation. If the system is not reset, it may not provide a

low tire pressure warning when necessary. See the TPMS reset

procedure in this chapter.

INFORMATION CONTAINED ON THE TIRE SIDEWALL

Both U.S. and Canada Federal regulations require tire manufacturers to

place standardized information on the sidewall of all tires. This

information identifies and describes the fundamental characteristics of

the tire and also provides a U.S. DOT Tire Identification Number for

safety standard certification and in case of a recall.

Information on “P” type tires

P215/65R15 95H is an example of a

tire size, load index and speed

rating. The definitions of these

items are listed below. (Note that

the tire size, load index and speed

rating for your vehicle may be

different from this example.)

1. P: Indicates a tire, designated by

the Tire and Rim Association

(T&RA), that may be used for

service on cars, SUVs, minivans and

light trucks.

Note: If your tire size does not

begin with a letter this may mean it

is designated by either ETRTO

(European Tire and Rim Technical Organization) or JATMA (Japan Tire

Manufacturing Association).

2. 215: Indicates the nominal width of the tire in millimeters from

sidewall edge to sidewall edge. In general, the larger the number, the

wider the tire.

3. 65: Indicates the aspect ratio which gives the tire’s ratio of height to

width.

4. R: Indicates a “radial” type tire.
