constructed of steel wires which are
wrapped, or reinforced, by the ply cords.Cold tire pressureThe air pressure in a tire which has been
standing in excess of three hours, or driven
for less than one mile.Curb weightThe weight of a standard vehicle, including
any optional equipment fitted, and with the
correct fluid levels.Gross vehicle weightThe maximum permissible weight of a vehicle
with driver, passengers, load, luggage, and
equipment.kPa (kilo pascal)A metric unit used to measure pressure. One
kilo pascal equals approximately .145 psi.Maximum inflation pressureThe maximum pressure to which the tire
should be inflated. This pressure is given on
the tire side wall in lbf/in
2. Note: This pressure is the maximum allowed
by the tire manufacturer. It is not the pressure
recommended for use.
Maximum loaded vehicle weightThe sum of curb weight, accessory weight,
vehicle capacity weight, and production
options weight.Production options weightThe combined weight of options installed
which weigh in excess of 3 lb more than the
standard items that they replaced, and are
not already considered in curb or accessory
weights. PSI (lbf/in
2)
Pounds per square inch, unit of measure for
pressure.RimThe metal support for a tire, or tire and tube,
