Changing tires with TPMS
It is recommended that you always
have your tires serviced by a dealer
or qualified technician.
Each road
tire is equipped with a tire
pressure sensor mounted on the
wheel inside the tire connected
to the valve stem. The tire
pressure sensor must be unbolted
from the wheel prior to tire
removal. The sensor can be removed by loosening the nut at the
valve stem. Failure to remove the sensor may damage it.
The rubber
grommet (washer) between the wheel and the tire pressure sensor needs
to be replaced when any tire is changed to minimize air leaks.
The tire pressure should be checked periodically (at least monthly) using
a tire gauge, refer to
Tire inflation pressure
in this chapter.
INFORMATION CONTAINED ON THE TIRE SIDEWALL
Federal law requires 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 than 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).
