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.
SNOW TIRES AND CHAINS
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains.
Follow these guidelines when using snow tires and chains:
•
Use only cable type chains or chains offered by Ford as an accessory
or equivalent. Other conventional link type chains may contact and
cause damage to the vehicle’s wheel house and/or body.
•
Do not install chains on the front wheels. Chains on the front wheels
may interfere with suspension components.
•
Chains are not recommended for use on the optional P275/65R18 tire.
•
Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•
Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
•
If possible, avoid fully loading your vehicle.
