Consumer information and Reporting safety defects
Example:
The vehicle placard shows original tire size, rec-
ommended cold tire inflation pressure on each
tire at maximum loaded vehicle weight, seating
capacity and loading information.
Adverse safety consequences of under-in-
!
flation
Driving at high speeds with excessively low tire
pressures can cause the tires to flex severely
and to rapidly become hot. A sharp increase in
temperature could cause tread separation, and
failure of the tire(s). Possible resulting loss of ve-
13-6
hicle control could lead to an accident.
Measuring and adjusting air pressure to
!
achieve proper inflation
Check and, if necessary, adjust the pressure of
each tire (including the spare) at least once a
month and before any long journey. Check the
tire pressures when the tires are cold. Use a
pressure gauge to adjust the tire pressures to the
specific values. Driving even a short distance
warms up the tires and increases the tire pres-
sures. Also, the tire pressures are affected by the
ambient temperature. It is best to check tire pres-
sure outdoors before driving the vehicle. When a
tire becomes warm, the air inside it expands,
causing the tire pressure to increase. Be careful
not to mistakenly release air from a warm tire to
reduce its pressure.
