GLOSSARY OF TIRE TERMINOL-
OGYAccessory Weight – the combined weight
(in excess of those standard items which
may be replaced) of automatic transmis-
sion, power steering, power brakes, power
windows, power seats, radio, and heater,
to the extent that these items are available
as factory-installed equipment (whether
installed or not).
Cold Tire Inflation Pressure – the pressure
in a tire that has been driven less than 1
mile or has been standing for three hours
or more.
Curb Weight – the weight of a motor vehi-
cle with standard equipment including the
maximum capacity of fuel, oil, and coolant,
and, if so equipped, air conditioning and
additional weight optional engine.
Intended Outboard Sidewall – (1) the side-
wall 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 asymmetrical tire that
has a particular side that must always face
outward when mounted on a vehicle.
Maximum Inflation Pressure – the maxi-
mum cold inflation pressure a tire is
designed to support in normal service.
Maximum Loaded Vehicle Weight – the
sum of curb weight, accessory weight,vehicle capacity weight (total load capac-
ity), and production options weight.
Normal Occupant Weight – 68 kilograms
times the number of occupants specified in
the second column of Table 1 (shown
below).
Occupant distribution – distribution of
occupants in a vehicle as specified in the
third column of Table 1 (shown below).
Production Options Weight – the combined
weight of those installed regular production
options weighing over 2.3 kilograms in
excess of those standard items which they
replace, not previously considered in curb
weight or accessory weight, including
heavy duty brakes, ride levelers, roof rack,
heavy duty battery, and special trim.
Recommended Inflation Pressure – the
cold tire inflation pressure recommended
by a manufacturer.
Rim – metal support for a tire or tire and
tube assembly upon which the tire beads
are seated.
Vehicle Capacity Weight – the rated cargo
and luggage load plus 68 kilograms (150
lbs) times the vehicle’s designated seating
capacity.
Vehicle Maximum Load on the Tire – the
load on an individual tire that is determined
by distributing to each axle its share of the
maximum loaded vehicle weight and divid-
ing by two.Vehicle Normal Load on the Tire – the load
on an individual tire that is determined by
distributing to each axle its share of the
curb weight, accessory weight, and normal
occupant weight (distributed in accordance
with Table 1 shown below) and dividing by
2.

never exceed XXX kg or XXX lbs” on
your vehicle’s placard.
2) Determine the combined weight of the
driver and passengers that will be riding
in your vehicle.
3) Subtract the combined weight of the
driver and passengers from XXX kg or
XXX lbs.
4) The resulting figure equals the available
amount of cargo and luggage load
capacity. For example, if the “XXX”
amount equals 1400 lbs and there will
be five 150 lb passengers in your vehi-
cle, the amount of available cargo and
luggage load capacity is 650 lbs (1400
– 750 (5 x 150) = 650 lbs).
5) Determine the combined weight of lug-
gage and cargo being loaded on the
vehicle. That weight may not safely
exceed the available cargo and luggage
load capacity calculated in Step 4.
6) If your vehicle will be towing a trailer,
load from your trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the avail-
able cargo and luggage load capacity of
your vehicle.
Vehicle Loading Example
As an example, suppose that the Tire and
Loading Information label on your vehicle
indicates that your vehicle’s total load
capacity is 950 lbs. If you were to drive
your vehicle with one passenger, and the
total combined weight of you and your pas-
senger was 350 lbs, then the cargo andluggage capacity of your vehicle would be
600 lbs (950 – 350 = 600 lbs).
If you later added 2 more passengers, hav-
ing a combined weight of 325 lbs, the
cargo and luggage capacity of your vehicle
would be reduced from 600 lbs to 275 lbs
(600 – 325 = 275 lbs). As you can see, as
the number and combined weight of vehi-
cle occupants increase, the vehicle’s cargo
and luggage capacity decreases.
Suppose again, that you were to take a trip
in your vehicle with the same three pas-
sengers described above, and you decided
to tow a trailer having a trailer tongue
weight of 75 lbs. The cargo and luggage
capacity would be reduced again, to 200
lbs (275 – 75 = 200 lbs).
Determining Compatibility of Tire and
Vehicle Load Limits
The tires on your vehicle, when they are
inflated to the recommended tire inflation
pressure, have a load-carrying capacity
that is greater than the load that will be on
the tires when the vehicle is at its GVWR
or GAWR limit. Never use replacement
tires that have a load-carrying capacity
less than the original tires on your vehicle.
Tire load-carrying capacity information is
molded into the tire sidewall typically
shown as “Max. Load”. Use of replacement
tires with a lower load-carrying capacity
than the original tires, or failure to keep the
tires inflated to recommended tire pres-
sure, may reduce the GVWR or GAWR
limit of your vehicle.NOTE:
Use of replacement tires with a higher
load-carrying capacity than the original
tires, or using a tire inflation pressure
higher than the recommended tire inflation
pressure, will not increase the GVWR or
GAWR limit of your vehicle.
