We recommend that all work on t ires and
wheels be performed by an authorized Audi
dealer. They are familiar with recommended
procedures and have the necessary special
too ls and spare parts as we ll as the proper fa -
cilities for dispos ing of the old tires .
Authorized Audi dealers have the necessary
information about techn ical requ irements for
installing or changing tires and rims.
Replacing t ires and w heels
Tires should be rep laced at least in pairs and
not individua lly (for example both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure monitoring system
¢page 291.
Always buy rep lacement radial tires that have
the same specifications as the t ires approved
for your vehicle by Audi. Replacement tires
must always have the same load rating speci-
fication as the original equipment or approved
optional tires listed in the table ¢ page 277.
Audi-approved specification tires are specially
matched to your vehicle and its load limits,
and can contribute to the important road hold-
ing, driving character istics, and safety of the
vehicle. The table (¢page 277) lists specifica-
tions of the t ires approved for the Audi mod-
els covered by your Owner's Literature .
