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
different 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. 181. 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,
replace 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.
Applicable only in the United States and Canada
Tire wear and damage

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 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.

Compact spare wheel

Fig. 182 In the luggage compartment: Compact spare wheel.

x Do not drive faster than 50 mph (80 km/h)!
x Avoid full-throttle acceleration, hard braking and fast cornering!
x Do not use snow chains on the compact spare wheel.
x After installing the compact spare wheel, check the tire pressure as soon as possible.
Check the tire inflation pressure of the compact spare whenever you check the tire pressure of the
road wheels, at least once a month. 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 compact spare wheel can cause loss of vehicle control, a crash or other
accident, and serious personal injury.
x Never use a compact spare wheel if it is damaged or worn down to the wear indicators.
x In some vehicles, the 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. 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
special 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.
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 come on
after a couple of minutes.
If possible, attach the compact spare wheel or the tire you took off the vehicle securely in the
luggage compartment.

TEMPERATURE A Temperature stability of the tire at increased test bench speeds
(A, B or C).
Additional numbers found on the tire could either be tire manufacturer internal labels or
country-specific labels (such as for Brazil and China).

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
rotation.

8 TIN represents the serial number of the tire.

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
factory-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
circumference), 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.
