13-6 Consumer information and Reporting safety defects
TVehicle placard
The vehicle placard is affixed to the
driver’s side door pillar.
Example: The vehicle placard shows original
tire size, recommended cold tire infla-
tion pressure on each tire at maxi-
mum loaded vehicle weight, seating
capacity and loading information.
T Adverse safety consequences
of under-inflation
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to flex severely and to rapidly
become hot. A sharp increase in tem-
perature could cause tread separa-
tion, and failure of the tire(s). Possible
resulting loss of vehicle control could
lead to an accident. T Measuring and adjusting air
pressure to achieve proper infla- tion
Check and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and be-
fore 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
pressures. Also, the tire pressures are affected by the outside tempera-
ture. It is best to check tire pressure
outdoors before driving the vehicle.
When a tire becomes warm, the air in-
side it expands, causing the tire pres-
sure to increase. Be careful not to
mistakenly release air from a warm
tire to reduce its pressure.
„ Glossary of tire terminology
y Cold tire pressure
The pressure in a tire that has been
driven less than 1 mile or has been
standing for three hours or more. y Maximum inflation pressure
The maximum cold inflation pressure
to which a tire may be inflated. y Recommended inflation pres-
sure
The cold inflation pressure recom-
mended by a vehicle manufacturer. y Intended outboard sidewall
1)The sidewall that contains a
whitewall, bears white lettering or
bears manufacturer, brand, and/or
model name molding that is higher
or deeper than the same molding
on the other sidewall of the tire, or
2)The outward facing sidewall of an
