5 TIN represents the serial number of the tire.

Unidirectional tires
Unidirectional tires are designed to rotate only in one direction. Unidirectional tires have arrows on the
sidewalls that show the direction of rotation. Make sure you mount the tire so that it rotates in the
proper direction. The tire's performance with regard to hydroplaning, traction, noise, and wear is worse
if it is not mounted in the proper direction of rotation.
If you have to mount a tire opposite to its proper direction of rotation, you must drive more carefully,
since the tire is no longer being used as designed. This is particularly important on wet roads. You
must replace or remount the tire as soon as possible in order to restore the correct direction of
rotation.

WARNING
Using incorrect or unmatched tires and/or wheels or improper tire and wheel combinations
can lead to loss of control, collision and serious personal injury.
x Always use tires, wheels and wheel bolts that meet the specifications of the original
factory-installed tires or other combinations that have been specifically approved by the
vehicle manufacturer.
x All 4 wheels must be fitted with radial tires of the same type, the same size (tread
circumference), and the same tread pattern. Driving with different tires reduces vehicle
handling and can lead to a loss of control.
x Never drive faster than the maximum speed for which the tires installed on your vehicle
are rated because tires that are driven faster than their rated speed can fail suddenly.
x Overloading tires can cause heat build-up, sudden tire failure, including a blowout and
sudden deflation and loss of control.
x Temperature grades apply to tires that are properly inflated and not over- or underinflated.
Winter tires

WARNING
Driving faster than the maximum speed for which the winter tires on your vehicle were
designed can cause sudden tire failure including a blowout and sudden deflation, loss of
control, crashes and serious personal injuries.
x Winter tires have a maximum speed rating that may be lower than your vehicle's maximum
speed.
x Never drive faster than the maximum speed for which the winter tires installed on your
vehicle are rated because tires that are driven faster than their rated speed can fail suddenly.
x Never exceed the maximum load rating for the winter tires installed on your vehicle.
Install summer tires promptly in the spring. Summer tires offer better handling characteristics for
temperatures above +45 °F (+7 °C). They are quieter, do not wear as quickly, and reduce fuel
consumption.
The Tire Pressure Monitoring System must be recalibrated using the SET button whenever you
remove and remount or change any wheel or tire on the vehicle, even if the reinstalled or replacement
wheels and tires are identical to those that were removed and even if the tire pressure does not
change or! Bookmark not defined..
If necessary, ask your authorized Volkswagen dealer or authorized Volkswagen Service Facility
about permissible winter tire dimensions.
Snow chains

WARNING
Using the wrong snow chains or installing snow chains improperly can cause accidents and
severe personal injuries.
x Always use the proper snow chains.
x Follow the installation instructions provided by the snow chain manufacturer.
x Never exceed the permissible speed limit when driving with snow chains.
NOTICE
x Remove snow chains when roads are free of snow. Otherwise, the chains can damage the
tires, impair vehicle handling and can be quickly worn down.
x Snow chains can scratch or damage wheel rims if they have direct contact with the rims.
Volkswagen recommends using coated snow chains.
Glossary of tire and loading terminology

Cold tire 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.
Curb weight
The weight of a motor vehicle with standard equipment including the maximum capacity of fuel, oil,

Gross Vehicle Weight Rating (GVWR)
The maximum loaded weight of the vehicle.
Groove
The space between 2 adjacent tread ribs.
Load rating (code)
The maximum load that a tire is rated to carry for a given inflation pressure. You may not find this
information on all tires because it is not required by law.
Maximum load rating
The load rating for a tire at the maximum permissible inflation pressure for that tire.
Maximum loaded vehicle weight
The total of:
x Curb weight.
x Accessory weight.
x Vehicle capacity weight.
x Production options weight.
Maximum (permissible) inflation pressure
The maximum cold inflation pressure to which a tire may be inflated. Also called “maximum inflation
pressure.”
Normal occupant weight
Means 150 lbs (68 kilograms) times the number of occupants seated 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, including the additional width of
labeling, decorations, or protective bands or ribs.

Passenger car tire

gross vehicle weight rating (GVWR) of 10,000 pounds or less.
Ply
A layer of rubber-coated parallel cords.
Ply separation
A parting of rubber compound between adjacent plies.

A mechanical device made of rubber, chemicals, fabric, and steel or other materials, that, when
mounted on an automotive wheel, provides 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 then 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

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.
Reinforced tire

of their useful life , Tread depth and tread wear indicators.
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 standards. 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
affected 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.
