• 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.

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.
