Winter tires improve the handling characteristics of your vehicle significantly when driving under wintry
road conditions. Summer tires have less traction on snow and ice because of their design (width,
rubber composition, tread design). Volkswagen strongly recommends that you always have winter
tires or all-season tires installed on all 4 wheels on your vehicle, especially when winter road
conditions are expected. Winter tires also improve the vehicle's braking performance and help reduce
stopping distances during winter weather. Volkswagen recommends installing winter tires once
temperatures are below +45 °F (+7 °C).
Winter tires are no longer suitable for winter driving once the tread pattern is worn down to a depth of
3/16 in (4.8 mm). In addition, winter tire performance decreases with age – independent of the tread
profile depth.
When using winter tires:
x Obey state and country-specific legal requirements.
x Install winter tires on all 4 wheels.
x Use winter tires only under wintry road conditions.
x Only use winter tires with dimensions approved for the vehicle.
x Use only winter tires of the same tire belt design, the same dimensions (tread circumference), and
the same tread design.
x Follow speed restrictions according to the winter tire's speed rating code letter ⇒.
Speed restrictions
Winter tires are certified up to a top speed identified by speed rating code letters on the side wall .
In some vehicle models it is possible to set a speed warning in the menu in the instrument cluster
display
Top speed rating and tire inflation pressure for V winter tires depend on the engine installed in your
vehicle. Be sure to ask you authorized Volkswagen dealer or authorized Volkswagen Service Facility
about the maximum permissible speed and the required tire inflation pressure for the winter tires that
you plan to use.
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

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
A tire intended for use on passenger cars, multipurpose passenger vehicles, and trucks, that have a
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.

Pneumatic tire
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
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.
Reinforced tire
A tire designed to operate at higher loads and at higher inflation pressures than the corresponding
standard tire.
Rim
The outer edge of a wheel upon which the tire beads are seated.
Rim diameter
The nominal diameter of the wheel's tire bead seating surface. If you change your wheel size, to
wheels of a different diameter, you will have to purchase new tires to match the new wheels.
Rim size
Designation means rim diameter and width.
Rim type designation
The industry or manufacturer's designation for a rim by style or code.
Rim width
The nominal distance between wheel rim flanges.
Section width
The linear distance between the exteriors of the sidewalls of an inflated tire, excluding elevations due
to labeling decoration, or protective bands.
Sidewall
The portion of a tire between the bead and the tread.
Sidewall separation
The parting of the rubber compound from the cord material in the sidewall.

Wheel size designation
Wheel rim diameter and width.
