the right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire wit h a tread pa tte rn
intended for use in a specific direction , pl ease
note the following:
- The direc tion o f rota tion is marked by an a r­
r ow on the side o f the tire.
- If the spare tire has to be i nst alled in the in ­
correct di rection in the even t of a flat tire,
use the spare tire on ly tempo rari ly since the
tire will not be ab le to ac hieve its opt imum
per formance characterist ics w ith regard to
aquapla ning, no ise and wear.
- We recommend that particular attent ion be
paid to this fact dur ing wet weather and
t h at you adjust your speed to matc h road
co ndit io ns.
What do I do now? 241
- Replace the flat ti re with a new one and
have it installed on your vehicle as soon as
possible to restore the hand ling advantages
of a properly pointed direction-dependent
tire .
Notes on wheel change
Please read the informat ion ¢ page 223, New
tires and r eplacing tires and wheels

After you change a tire :
-Check the tire pressu re on the spare imme­
diately after mounting.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as
possible by your authorized Audi dealer or
a qualifi ed service station.
- On steel and alloy wheel rims, the wheel
bolts are cor rectly tightened with a torque
of 90 ft lb (120 Nm).
- If you notice while changing a tire that the
wheel bolts are corroded and difficult to
turn, then they should be replaced befor e
you check the tightening torque .
- Replace the flat tire with a new one and
have it installed on your veh icle as soon as
possible. Remount the wheel cover.
Until then, dr ive with e xtra care and at re­
duced speeds .
