ture . For example, the numbers 2207 mean the tire was produced in
t he 22nd
week of 2007 . The other numbers are marketing codes that
may or may not be used by the tire manufacturer . This information
is used to contact consumers if a tire defect requires a recall.
T ire p ly co mpos ition and mate ria ls used
The number of plies indicates the number of layers of rubber -coated
fabric in the tire . In genera l, the greater the number of p lies, the
more weight a tire can support. Tire manufacturers also must ind i­
cate the materials in the tire, which include steel, ny lon, polyester,
and others.

pr ess ur e monit orin g sy st em
T he wheels on your vehicle are equipped with a sensor which
constantly monitors the air pressure inside the tire , and then trans ­
m its this information to the tire pressure mon itoring system. If you
are going to replace the whee l rims on your vehicle, make sure the
n ew rims also have t hese sensors. The sensors mus t be compa tible
with the tire pressure monitoring system on your vehicle .
I f you instal l rims, which do not have the sensors, or have sensors
whic h are not compatible, then the t ire pressure monitoring system
wi ll not work properly. In this case, the tire pressure monitoring
system would not be ab le to mon itor the tire pressure or warn you
if it is necessary . .,_

&, WARNING (continued )
• Never drive faster than the speed for which the winter or other
tires in stalled on your vehicle are rated.
& WARNING
Always adjust your driving to the road and traffic condit ions .
Never let the good acceleration of the winter tires and all -wheel
dri ve tempt you into taking extra risks. Always remember :
• When braking , an all -wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and reduce your speed on icy and slippery roads ,
even winter tires cannot help under bla ck ice conditions.
c£> For the sake of the environment
Use summer tires when weather conditions permit. They are
q uiete r, d o not wear as qui ckly a nd r educe fuel cons ump tion.•

incorrectly can in crease the risk of loss of control leading to
serious personal injury .

_ e_e_ l_ s _______________________________________________ _
• After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a
damaged tire as soon as possible .
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see . Damage can lead to loss of
air and underinflation, which could eventua lly cause tire fai lure. If
you be lieve that a tire may have been damaged, replace the tire as
soon as possib le .
• These tires may wear more quickly than others .
• Please a lso remember that, whi le t hese tires deliver responsive
handling, they may ride less comfortably and make more noise than
other choices.

c ondi tion s
All tires are designed for certain purposes. The low aspect ratio,
u ltra hig h performance t ires orig inally instal led o n your vehic le are
intended for maximum dry and wet road performance and hand ling.
They are no t suitable for cold, snowy or icy weather condit ions . If
you drive under those circumstances, you should equip your vehicle
with al l- season or winter tires, which offer better traction under
those conditions . We suggest you use the recommended snow or
a ll-season tires specified for your vehicle, or their equiva lent.
