Owners Manual

Weight Rating is specified on the vehicle
identification plate on the driver seat frame
(Y page 285).
Maximum weight of the laden vehicle
The maximum weight is the sum of the curb
weight of the vehicle, the weight of the
accessories, the maximum load and the
weight of the optional equipment installed at
the factory.
Kilopascal (kPa)
Metric unit for tire pressure. 6.9kPa is
equivalent to 1psi. Another tire pressure unit
is bar. 100kilopascal (kPa) is equivalent to
1bar.
Load index
In addition to the load bearing index, a load
index can be stamped onto the sidewall of the
tire. It specifies the load-bearing capacity of
the tire more precisely.
Curb weight
The weight of a vehicle with standard
equipment including the maximum filling
capacity of fuel, oil, and coolant. It also
includes the air-conditioning system and
optional equipment if these are installed on
the vehicle, but does not include passengers
or luggage.
Maximum tire load
The maximum tire load in kilograms or
pounds is the maximum weight for which a
tire is approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one
tire.
Maximum load on one tire
Maximum load on one tire. This is calculated
by dividing the maximum axle load of one axle
by two.
PSI (Pounds per square inch)
Standard unit of measurement for tire
pressure.
Aspect ratio
Relationship between tire height and width in
percent.
Tire pressure
Pressure inside the tire applying an outward
force to every square inch of the tire's
surface. Tire pressure is specified in pounds
per square inch (psi), in kilopascal (kPa) or in
bar. Tire pressure should only be corrected
when the tires are cold.
Tire pressure of cold tires
The tires are cold:
R
if the vehicle has been parked for at least
three hours without direct sunlight on the
tires, and
R
if the vehicle was driven less than 1 mile
(1.6 km).
Tire tread
The part of the tire that comes into contact
with the road.
