make sure t he tre ad pat­
t er n is poin ted t he righ t way
c;, page277.
- Th e wheel bolts shou ld be clean and easy
to t urn. Check for dirt an d corrosion on
the mating surfaces of both the w heel

and the hub. R emove a ll dirt from these
su rfaces before remo unt ing the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread de sign must be
mounted with their tread pattern pointed in
the right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spa re tire w ith a tread patte rn
intended for use in a specific direction, please
note t he following:
- T he direction o f rotation is marked by an a r­
r ow on the side of the tire.
- If the sp are tire has to be install ed in the in­
correct di rection, use the spare tire only
temporar ily since the t ire wi ll not be a ble to
ac hieve its optimum performance character­
ist ics with regard to aquaplaning, noise and
wear.
- We recommend that you pay particular at­
tent ion to this fact during wet weat her and
t h at you adjust your speed to matc h road
condit ions .
- Replace the flat tire w ith a new one and
have it installed on your ve hicle as soon as
poss ib le to restore the hand ling advantages
of a uni direct io na l ti re.
Notes on wheel changing
Please read the information ¢ page 259, New
t ires and repl acing tires and wheels
if you are
goi ng to use a s pare t ire which is differen t
from the tires on your ve hicle.
Afte r you change a tire:
- Check the tire pressure on the spare imme­
diately after installation .
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as
possible by your authorized Audi dealer or
a qualified s ervice station .
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lb (120 Nm). What do I do now? 277
- If you notice that the wheel bolts are cor­
roded and difficult to turn while changing
a tire , they should be replaced before you
check the t ightening torque.
- Replace the flat ti re with a new one and
have it installed on your vehicle as soon as
possible. Remount the wheel cover.
Until then , drive with extra care and at re­
