At least once a month or before long trips, inspect each tyre and
check the tyre pressure with a tyre gauge (including spare tyre).
Inflate all tyres to the recommended inflation pressure.
Tyres with correct pressure help in improving the fuel efficiency.
Besides improving the tyre life
Underinflation is the most common cause of tyre failures and
may result in severe tyre cracking, tread separation or
“blowout”, with unexpected loss of vehicle control and increased
risk of injury. Underinflation increases sidewall flexing and rolling
resistance, resulting in heat buildup and internal damage to the
tyre. It also may result in unnecessary tyre stress, irregular
wear, loss of vehicle control and accidents.
Always inflate your tyres to the recommended pressure even if it is
less than the maximum inflation pressure information found on the
tyre. The recommended tyre inflation pressure is found on the tyre
Label which is located on the front passenger side inner B-pillar.
Failure to follow the tyre pressure recommendations can cause
uneven tread wear patterns and adversely affect the way your
vehicle handles.
If you overfill the tyre, release air by pushing the metal stem in
the center of the valve. Then recheck the pressure.
After inspecting or adjusting the tyre pressure, always reinstall
the valve stem cap (if equipped). This will prevent moisture and
dirt from entering the valve stem, which could damage the
stem, resulting in an unexpected loss of tyre pressure, an
accident and/or personal injury.
12.4.3 Radial Ply tyres
Combining radial ply tyres with other types of tyres on your
vehicle will cause your vehicle to handle poorly, resulting in an
accident and/or personal injury. Always use radial tyres in sets
of four. Never combine them with other types of tyres.
Cuts and punctures in radial tyres are repairable only in the
tread area because of sidewall flexing. Consult your authorized
dealer for radial tyre repairs.
12.4.4 Tread Wear Indicators (TWI)
Tread wear indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth becomes
1/16 inch (1.6 mm). When the indicators appear in two or more
adjacent grooves, the tyre should be replaced.
