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, 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.
Dispose of the wheel electronics and the old batteries in an environmentally responsible manner. Batteries of the type used in the wheel electronics may contain Perchlorate Material. Special handling may apply. See www.dtsc.ca.gov/hadardouswaste/perchlorate. Obey all applicable legal requirements regarding proper disposal.
Do not rely only on the Tire Pressure Monitoring System. Check your tires regularly to make sure they are properly inflated and have no signs of damage, such as punctures, cuts, cracks, and blisters. Remove any objects that become embedded in the tire tread but have not penetrated into the body of tire itself.
The Tire Pressure Monitoring System checks for the factory-recommended inflation pressure, as shown on the label inside the driver door, Tire inflation pressure.
x For replacement tires that require a different inflation pressure, the TPMS must be adjusted to the new pressure specification by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. Only one value can be entered for each tire; see the tire inflation pressure label on the driver
door pillar ⇒ page 240, Tire inflation pressure.
x To help prevent damage to the sensor and valve, do not put excessive force on the valve when checking the tire pressure. Do not try to bend the valve.
x If sensors have to be replaced, have the valves changed at the same time.
x The tire valve gaskets must be replaced whenever a tire is mounted on the rim. Your authorized Volkswagen dealer or authorized Volkswagen Service Facility has a valve seal and gasket kit for this purpose. Always make sure that a valve seal and gasket kit is also used whenever a sensor is replaced.
x If you have to adjust the tire pressure on a “warm” tire, fill the tire with 2.0 - 4.35 psi (20 - 30 kPa) more than the pressure specified on the tire pressure label.
x When the TPMS determines that the air pressure in at least one tire is too low, carefully check the pressure in all 4 tires with an accurate tire pressure gauge. Low tire pressure usually cannot be determined by looking at the tire. This is especially true of low-profile tires.
A Declaration of Compliance with the United States FCC and Industry Canada regulations is found in the Consumer Information section of this Manual, Declaration of Compliance, Telecommunications and Electronic Systems.
There may be differences between the pressure readings from a tire pressure gauge and the pressures registered by the Tire Pressure Monitoring System. The electronic TPMS is more accurate.
If you have work done on your wheels or tires, inform the workshop that the vehicle is equipped with a Tire Pressure Monitoring System that has sensors in the wheels.
