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. 106. 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.
Never drive a vehicle when the tread on any tire is worn down to the wear indicators,
replace them sooner.
Worn tires do not grip the road properly, especially on wet roads, increasing your risk of
“hydroplaning” and loss of control.
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
Please first read and note the introductory information and heed the WARNINGS
Wheel rim and tire damage is often difficult to see. Unusual vibrations or pulling to one-side can be
an indication of tire damage ⇒ .
If you suspect tire damage, immediately reduce speed!
Check tires and wheel rims for damage.

stuck in the tread grooves of the tire, they can be removed.
If necessary, change the damaged wheel ⇒ Changing a wheel. If necessary, get professional
assistance to change the wheel.
Check tire pressure and adjust if necessary.
Tire wear
Tire wear depends on several factors, including:
Driving style.
Unbalanced wheels.
Wheel alignment.
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
