Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv
ing style.

Tread Wear Indicator (TWI)
The o rigi na l t ires on your veh icle have
1/16 inch (1.6 mm) high "wear indicators"
c::> fig . 176 running across the tread. Depend
i ng on the make, there will be six to eight of
them evenly p laced around the t ire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced .
Different fig ures may apply in o ther countries

Tire p ressure
Incorrect tire pressure causes premature wear
a nd can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
c::> page 236.
Driving style
Driving fast aro und curves, heavy acce leration
and hard braking increase tire wear.
Rotating tires for more even wear
F or all four tires on your ve hicl e to h ave the
same service life, we recommen d that t he
front and rear t ires are rotated according to
the tire manufact urer's suggested tire rota
tion intervals. Please remember the follow ing :
- Tire rotation intervals may differ from the
vehicle service inte rva ls o utlined in your
Ma intenance and Warranty Book let .
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufact urer's suggested
tire rotation intervals .
- Vehi cles w ith front-wheel dr ive experience
more tread wear on the fro nt w heels com
pa red to all wheel d rive (quattro ®).
- Please rotate tires as shown
c::> fig. 177.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 2 5 7 .
Wheel balancing
The wheels on new ve hicles are balanced .
However, various situations during everyday
driving can cause them to become unba l
anced, re sulting in vibrat ions you can usually
feel through the steer ing wheel.
Un balanced whee ls must be rebalanced to
avoid excessive wear on steering, suspension
and t ires. A whee l m ust also be reba lanced
when a new tire is insta lled.
Incorrect wheel alignment
Incor rect wheel alig nment can cause exces
sive tire wear, impairing the safety of the veh i
cle . If tires show excessive wear, have the
whee l alignment checked by an aut hori zed
Audi dealer or qualif ied workshop .
All wheel drive
Vehicles with q uattro ® mus t always have tires
of the same size, construction and tread type .
