in the vehicle up to the total seating capacity of your vehicle.
Occupant distribution
The placement of passengers in a vehicle.
Outer diameter
The diameter of a new, properly inflated tire.
Overall width
Total width measured at the exterior sidewalls of an inflated tire, in-
cluding the additional width of labeling, decorations, or protective
bands or ribs.
Passenger car tire

vides the traction and contains the gas or fluid that sustains the load.
Production options weight
The combined weight of installed regular production options weighing
over 5 lbs (2.3 kg) more than the standard items they replace, and not
previously considered as curb weight or accessory weight. These
include, for example, heavy-duty brakes, ride levelers, roof rack,
heavy-duty battery, and special trim.
Radial ply tires
A pneumatic tire in which the ply cords that extend to the beads are
laid at substantially 90 degrees to the centerline of the tread.

Recommended inflation pressure
The tire pressure recommended by the vehicle manufacturer for a tire
of a specified size that has not been driven for more than a couple of
miles (kilometers) at low speeds in the 3 hour period before the tire
pressure is measured or adjusted.

sidewall.

Speed rating (letter code)
A standardized letter code indicating the maximum speed at which a
tire is designed to be driven for extended periods of time. The ratings
range from 93 mph or 150 km/h (“P”) to 186 mph or (300 km/h) “Y”.
The speed rating letter code, where applicable, is molded on the tire
sidewall. You may not find this information on all tires because it is
not required by law.
Tire Pressure Monitoring System
A system that detects when at least one of a vehicle's tires is underin-
flated and illuminates a low tire-pressure warning light.
Tread
The portion of a tire that normally touches the road.
Tread rib
A tread section running circumferentially around a tire.
Tread separation
Tire failure caused by the tread pulling away from the tire carcass.
Tread wear indicators (TWI)
Raised areas within the main tread grooves that show, visually, when
tires are worn and near the end of their useful life ⇒ page 261.
Uniform Tire Quality Grading (UTQG)
A tire information system developed by the U.S. National Highway
Traffic Safety Administration (NHTSA) that is designed to help buyers
compare tires. UTQG is not a safety rating, nor is it a guarantee that a
tire will last for a certain number of miles or perform a certain way. It
gives tire buyers more information to compare with factors such as
price, brand loyalty and dealer recommendations. Under UTQG, tires
are graded by the tire manufacturers in 3 areas: tread wear, traction
and temperature resistance. UTQG information is molded into the tire
sidewalls.
U.S. DOT Tire Identification Number (TIN)
A tire's serial number. It begins with the letters “DOT” (“Department of
Transportation”) and indicates that the tire meets all federal stand-
ards. The next 2 numbers or letters indicate the plant where the tire

was manufactured. The last 4 numbers represent the week and year
of manufacture.
For example, the numbers 1709 mean that the tire was produced in
the 17th week of 2009. Any other numbers are marketing codes used
by the tire manufacturer. This information is used to help identify af-
fected consumers if a tire defect requires a recall.
Vehicle capacity weight
The total rated cargo, luggage and passenger load. Passenger load is
150 lbs (68 kilograms) times the vehicle's total seating capacity (as
listed on the label inside the driver door).
Vehicle maximum load on the tire
The load on an individual tire that is determined by taking each axle's
share of the maximum loaded vehicle weight (GAWR) and dividing
by 2.
Vehicle normal load on the tire
The load on an individual tire that is determined by taking each axle's
share of the curb weight, accessory weight, and normal occupant
weight (distributed according to the table below) and dividing by 2.
Wheel size designation
Wheel rim diameter and width.

Tires and vehicle load limits

There are limits to the load any vehicle or any tire can carry. A vehicle
that is overloaded will not handle well and is more difficult to stop.
Overloading can damage important parts of the vehicle. Overloading
can also lead to blowout, sudden loss of pressure or other tire failure
that can cause loss of control.
Your safety and the safety of your passengers depends on making
sure that load limits are not exceeded. Vehicle load includes every-
body and everything in and on the vehicle. These load limits are
technically referred to as the vehicle's Gross Vehicle Weight Rating
(GVWR).
The GVWR includes the weight of the basic vehicle, all factory-
installed and other accessories, a full tank of fuel, oil, coolant and
other fluids plus maximum load. The maximum load includes the
number of passengers that the vehicle is intended to carry (seating
capacity) with an assumed weight of 150 lbs (68 kg) for each passen-
ger at a designated seating position and the total weight of any lug-
gage in the vehicle. If you tow a trailer, the weight of the trailer hitch
and the tongue weight of the loaded trailer must be included as part
of the vehicle weight. At altitudes above 3000 ft (1000 m), combined
towing weight (vehicle plus trailer) must be reduced by 10% for every
3000 ft (1000 m).
The Gross Axle Weight Rating (GAWR) is the maximum load that
can be carried at each of the vehicle's 2 axles (by the front or rear
tires). GVWR and GAWR are listed on the safety compliance label on
the driver door jamb. Because there is an upper limit to your vehicle's
total weight (GVWR), the weight of whatever is being carried (includ-
ing the weight of a trailer hitch and the tongue weight of the loaded
trailer) is also limited. More passengers, or passengers who are heav-
ier than the assumed 150 lbs (68 kg), mean that less weight can be
carried as luggage or other cargo. The tire pressure label on your
Volkswagen also lists the maximum combined weight of all of the oc-
cupants and luggage or other cargo that the vehicle can carry.

WARNING
Overloading a vehicle can cause loss of vehicle control, a crash
or other accident, serious personal injury, and even death.
Carrying more weight than your vehicle was designed to car-
ry will prevent the vehicle from handling properly and increase
the risk of the loss of vehicle control.
The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle in a safe distance.
Tires on a vehicle that has been overloaded can fail sudden-
ly, including a blowout and sudden deflation, causing loss of
control and a crash.
Always make sure that the total load being transported – in-
cluding the weight of a trailer hitch and the tongue weight of a
loaded trailer – does not make the vehicle heavier than the ve-
hicle's Gross Vehicle Weight Rating.
Determining the correct load limit

Steps for Determining Correct Load Limit:
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 vehicle, 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 luggage 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 available cargo and luggage capacity of
your vehicle.
Check the tire sidewall to determine the load index specified for
the tire.
