WARNING
Incorrect tire pressure can cause a sudden tire failure or blowout, loss of control, collision, serious personal injury, and even death.
x Always inflate tires to the recommended and correct cold tire pressure before driving off.
x Low tire pressure can cause tires to get too hot, resulting in tread separation, sudden loss of pressure, and blowouts. Tires with excessively low pressure flex (bend) more, which can cause the tire to overheat and fail suddenly without warning.
x Excessive speed and/or overloading can cause heat buildup, sudden tire failure including a blowout and sudden deflation and loss of control.
x If the tire pressure is too low or too high, the tires will wear prematurely and the vehicle will not handle well.
x Regularly check tire inflation pressure, at least once a month, and also especially before a long trip.
x Check the pressure in all 4 tires when the tires are still cold. Never reduce air pressure in warm tires to match cold tire inflation pressure.
NOTICE
x Make sure not to jam the tire pressure gauge into the valve stem. Otherwise you can dam-age the tire valves.
x Driving without valve caps, with the wrong valve caps, or with valve caps that are not properly screwed on can damage the tire valves. To help prevent damage, always use valve stem caps like those originally installed at the factory. The caps must be screwed on tightly. Do not use metal valve caps or “comfort” valve stem caps.
Underinflation increases power consumption.
When the TPMS warns that the pressure in at least one tire is too low, check the tire pressure in all 4 tires with an accurate tire pressure gauge. Low tire pressure usually cannot be spotted by looking
at the tire. This is especially true for low-profile tires. When checking the tire pressures, refer to ⇒  Tire Pressure Monitoring System (TPMS).
Tire inflation pressure in cold tires

Tire size Standard tire pressure
(full load)
psi kPa bar
The Tire Pressure Monitoring System is configured at the factory with the
correct tire inflation pressure applicable for the vehicle model, electric mo-
tor and factory-installed tires. The tire inflation pressure is listed on the tire
inflation pressure label on the driver door jamb ⇒ fig. 99. The tire inflation
pressures for the road tires are listed on this label. The inflation pressure
for the compact spare is as specified on the tire pressure label or on a
separate label for the compact spare, if there is one. In the event of a dis-
crepancy between the above figures and the tire pressures listed on the
tire inflation pressure label, the pressures listed on the label are the ones
you should use. The listed pressure applies to all road tires. The Tire
Pressure Monitoring System must be recalibrated whenever you change
or adjust the cold tire inflation pressures or remove and remount or
change any wheel or tire on the vehicle, even if the reinstalled or replace-
ment wheels and tires are identical to those that were removed and even if
the tire pressure does not change

Tread depth and tread wear indicators

Fig. 100 Tread pattern: Wear indicator.

Page 160 of 394


Winter tires are no longer suitable for winter operation once the tread pattern is worn down to a depth of 3/16 in. (4.8 mm).
The tread depth of new tires can differ between tire models and manufacturers because of the differ-ent design features and tread patterns.
Tread wear indicator (TWI) in the tire
The 1/16 in. (1.6 mm) high wear indicators are molded into the bottom of the tread grooves of the
original tires running across the treads ⇒ fig. 100. Several wear indicators are evenly spaced around the tire. Markings on the sides of the tires (for example “TWI” or symbols) show the position of the wear indicators.
Wear indicators show when the tires are worn down. The tires must be replaced no later than when the tread pattern is worn down to the wear indicators.
WARNING
Worn tires are dangerous and can cause loss of vehicle control including serious personal injuries.
x Never drive a vehicle when the tread on any tire is worn down to the wear indicators, re-place them sooner.
x Worn tires do not grip the road properly, especially on wet roads, increasing your risk of “hydroplaning” and loss of control.
x Worn tires reduce the ability of your vehicle to handle well in normal and difficult driving situations and increase braking distances and the risk of skidding.
Tire wear and damage

Page 161 of 394


Driving style – Fast cornering, hard acceleration and braking increase tire wear. If you experience increased tire wear under normal driving conditions, have the vehicle suspension checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Unbalanced wheels – The wheels on a new vehicle are balanced. When driving, however, various conditions can cause a wheel to become unbalanced. Unbalanced wheels can cause wear to the steering and suspension systems. Have all wheels rebalanced. A wheel must always be rebalanced if a new tire has been mounted.
Wheel alignment – Incorrect wheel alignment causes excessive and uneven tire wear, impairing vehicle safety. If you notice excessive or uneven tire wear, have the wheel alignment checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
WARNING
Unusual vibrations or pulling to one side can indicate tire damage.
x Reduce speed immediately and stop when it is safe to do so.
x Check tires and wheel rims for damage.
x Never drive with a damaged tire or rim. Get expert assistance instead.
x If no external damage is visible, slowly and carefully drive to the nearest authorized Volkswagen dealer, authorized Volkswagen Service Facility, or other qualified workshop and have the vehicle checked.
Spare wheel or compact spare wheel

Page 163 of 394


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

Page 167 of 394


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.
