-~_T_ ir_e_ s_ a_ n_d _ w_ h_ 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 possib le .
• 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 failure. If
you believe that a tire may have been damaged, replace the tire as soon as possible .
• These tires may wear more quickly than others.
• Please a lso remember that, whi le these tires deliver responsive
handling, they may ride less comfortably and make more noise than
other choices.

c ondi tio ns
All tires are designed for certain purposes. The low aspect ratio,
u ltra high performance tires originally ins tal led o n your vehicle are
intended for maximum dry and wet road performance and hand ling.
They are no t suitable for cold, snowy or icy weather conditions . 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.
