x After installing the spare wheel or compact spare wheel, check the tire pressure as soon as possi-
ble ⇒  Tire inflation pressure.
Check the tire inflation pressure of the spare or compact spare whenever you check the tire pressure of the road wheels, at least once a month. Inflate a spare wheel to the cold tire pressure specified for the vehicle's road wheels on the tire pressure label; inflate a compact spare wheel to the cold tire pressure specified for the compact spare on the tire pressure label or on a separate label for the compact spare, if there is one.
WARNING
Improper use of a spare wheel or a compact spare wheel can cause loss of vehicle control, a crash or other accident, and serious personal injury.
x Never use a spare wheel or compact spare wheel if it is damaged or worn down to the wear indicators.
x In some vehicles, the spare wheel or compact spare wheel is smaller than the original tire. A smaller compact spare wheel is identified with a sticker and the words “50 mph” or “80 km/h”. This is the maximum permissible speed when driving with this tire.
x Never drive faster than 50 mph (80 km/h) with a compact spare wheel. Avoid full-throttle acceleration, heavy braking, and fast cornering!
x Never drive more than 125 miles (200 km) if a compact spare wheel is installed on the front axle (drive axle).
x Replace the compact spare with a normal wheel and tire as soon as possible. Compact spare tires are designed for brief use only.
x Regularly check the U.S. DOT Tire Identification Number (TIN) to determine the age of the
compact spare wheel ⇒  Tire labeling. Tires age even if they are not being used and can fail suddenly, especially at higher speeds.
x Tires that are more than 6 years old can only be used in an emergency and then with spe-cial care and at lower speeds.
x The compact spare wheel must always be secured with the wheel bolts provided by the factory.
x Never drive using more than one compact spare wheel.
x After installing the compact spare wheel, the tire pressure must be checked as soon as
possible ⇒  Tire inflation pressure.
x Snow chains cannot be used on the compact spare wheel. If you must use snow chains and have a compact spare wheel mounted, move the compact spare wheel to the rear axle if a front tire has to be replaced. The tire taken off the rear axle can then be used to replace the flat front tire. Be sure you do not change the tire's direction of rotation. Install the snow chains on the full-sized road tire.
NOTICE
When the spare wheel or compact spare is being used, the TPMS indicator light can light up
after a couple of minutes ⇒  Tire Pressure Monitoring System (TPMS).
If possible, attach the spare wheel, compact spare wheel, or the wheel you took off the vehicle securely in the luggage compartment.

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 rota-tion.

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 facto-ry-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 circum-ference), 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 de-signed can cause sudden tire failure including a blowout and sudden deflation, loss of con-trol, 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 power consumption.
The Tire Pressure Monitoring System must be recalibrated 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 ⇒  Tire Pressure Monitoring System (TPMS) and recalibration through the Infotainment system.
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.

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 guaran-tee 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.
