x The tread depth of new tires can differ between tire models and manufacturers because of different design features and tread design.
Replacing tires
x Tires should be replaced in pairs and not individually (both front tires or both rear tires at the same
time) ⇒ .
x Replace tires only with tires that have the same specifications, including width and diameter, load and top speed rating as the tires approved by Volkswagen for your vehicle and model.
x Never use tires that are larger or wider than the dimensions of the tires approved by Volkswagen for your vehicle and model. Larger tires could scrape and rub on the vehicle body or other parts of the vehicle.
Tire Pressure Monitoring System (TPMS) considerations
Factory-installed wheels are equipped with a sensor that constantly monitors tire pressure, then
transmits this information to the TPMS ⇒  Tire Pressure Monitoring System (TPMS). If you are going to replace the wheels, make sure that the new wheels also have sensors that are compatible with the TPMS on your vehicle. New wheels with sensors have to be recognized and integrated into the sys-tem. The new wheels and sensors are recognized and integrated when driving off the first time.
If you install wheels that do not have sensors, or have sensors that are not compatible, the TPMS will not work properly. In this case, the TPMS will not be able to monitor tire pressure or warn you if pres-sure is low. An error message may appear in the instrument cluster display or the TPMS will switch itself off.
x Whenever you change sensors, you have to install new valves and seals. Please see an author-ized Volkswagen dealer of an authorized Volkswagen Service Facility.
x Always drive with the valve caps securely installed. We recommend using factory-supplied valve caps. Ask an authorized Volkswagen dealer or an authorized Volkswagen Service Facility to replace lost caps.
If you install new tires that differ the original Volkswagen specifications, for your vehicle and model, the benchmark tire inflation pressure values stored in your vehicle's TPMS may have to be adjusted (reprogrammed). This requires professional assistance. For more information, contact your authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Installing replacement tires with steel cord body plies in the tire sidewall may cause malfunction of the TPMS, and is not recommended (cord material information in molded on the tire sidewall).
Always check the TPMS indicator light after replacing one or more tires on your vehicle. If the indicator light is on, the TPMS is not working properly. Your replacement tire might be incompatible with the system, or some component of the TPMS may be damaged.
For detailed information about TPMS, how it works and what you need to know ⇒  Tire Pressure Monitoring System (TPMS).
WARNING
New tires tend to be slippery and must be broken in.
x Always drive with special care for the first 350 miles (560 km) to help reduce the risk of losing control, a collision, and serious personal injuries.
