3.3 StepS for determInIng correct load
lImIt - tow VehIcle
1. Locate the statement, “The combined weight of
occupants and cargo should never exceed XXX
lbs.,” on your vehicle’s placard.
2. Determine the combined weight of the driver and
passengers who will be riding in your vehicle.
3. Subtract the combined weight of the driver and
passengers from XXX kilograms or XXX pounds.
4. The resulting gure equals the available amount
of cargo and luggage capacity. For example, if the
“XXX” amount equals 1400 lbs. and there will be
ve 150 lb. passengers in your vehicle, the amount
of available cargo and luggage capacity is 650 lbs.
(1400-750 (5 x 150) = 650 lbs.).
5. Determine the combined weight of luggage and
cargo being loaded on the vehicle. That weight may
not safely exceed the available cargo and luggage
capacity calculated in previous step.
6. If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. Consult
the tow vehicle’s manual to determine how this
weight transfer reduces the available cargo and
luggage capacity of your vehicle.
3.4 gloSSary of tIre termInology
Accessory weight: The combined weight (in excess
of those standard items which may be replaced) of
automatic transmission, 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).
Bead: The part of the tire that is made of steel wires,
wrapped or reinforced by ply cords and that is shaped
to t the rim.
Bead separation: This is the breakdown of the bond
between components in the bead.
Bias ply tire: A pneumatic tire in which the ply cords
that extend to the beads are laid at alternate angles
substantially less than 90 degrees to the centerline of
the tread.
Carcass: The tire structure, except tread and sidewall
rubber which, when inated, bears the load.
Chunking: The breaking away of pieces of the tread
or sidewall.
Cold ination pressure: The pressure in the tire
before you drive.
Cord: The strands forming the plies in the tire.
Cord separation: The parting of cords from adjacent
rubber compounds.
Cracking Any parting within the tread, sidewall, or
inner liner of the tire extending to cord material.
CT: A pneumatic tire with an inverted ange tire and rim
system in which the rim is designed with rim anges
pointed radially inward and the tire is designed to t on
the underside of the rim in a manner that encloses the
rim anges inside the air cavity of the tire.
Curb weight: The weight of a motor vehicle with
standard equipment including the maximum capacity
of fuel, oil, and coolant, and, if so equipped, air
conditioning and additional weight optional engine.
Extra load tire: A tire designed to operate at higher
loads and at higher ination pressures than the
corresponding standard tire.
Groove: The space between two adjacent tread ribs.
Gross Axle Weight Rating: The maximum weight that
any axle can support, as published on the Certication
/ VIN label on the front left side of the trailer. Actual
weight determined by weighing each axle on a public
scale, with the trailer attached to the towing vehicle.
Gross Vehicle Weight Rating: The maximum weight of
the fully loaded trailer, as published on the Certication
/ VIN label. Actual weight determined by weighing
trailer on a public scale, without being attached to the
towing vehicle.
Hitch Weight: The downward force exerted on the
hitch ball by the trailer coupler.
Innerliner: The layer(s) forming the inside surface of a
tubeless tire that contains the inating medium within
the tire.
Innerliner separation: The parting of the innerliner
from cord material in the carcass.
Intended outboard sidewall: The sidewall that
contains a white-wall, bears white lettering or bears
manufacturer, brand, and/or model name molding that
