Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed
immediately.
.,.Protect your tires from oil,
grease and fuel.
.,.Mark tires before removing
them so that the same running
direction can
be maintained if
they are reinstalled .
... Lay tires flat when storing and
store them in a cool, dry location
with
as little exposure to light as
possible.
CD Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­
crease the elasticity of summ­
er tires, which affects traction
250
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion
protection for this and
could be permanently dam­
aged by road salt or similar
substances.

comparisons among tires. The
UTQG is not a safety rating and
not a guarantee that a tire will
last for a prescribed number of
miles (kilometers) or perform in a
certain way. It simply gives tire
buyers additional information to
combine with other considera­
tions, such as price, brand loyalty
and dealer recommendations. Un­
der UTQG, tires are graded by the
tire manufacturers in three areas:
treadwear, traction, and tempera­
ture resistance. The UTQG in for­

the sidewalls.
U.S. DOT Tire Identification
Number (TIN)
T his is the t ire's "serial number".
It begins w ith the letters "DOT"
and indicates that the tire meets
all federal standards. The nex t
two numbers or letters indicate
the plant where it was manufac­
tured, and the last four numbers
represent the week and year of
manufacture. For example,
DOT ... 2214 ...
means that the tire was produced
in the 22nd week of 2014. The
other numbers are marketing co­
des that may or may not be used
2 5 6
by the tire manufacturer. T his in­
formation is used to contact con­
sumers if a tire defect requires a

Vehicle normal load on the tire
means that load on an individual
tire that is determined by distrib­
uting to each axle its share of the
curb weight, accessory weight,

tributed in accordance with¢ ta­
ble on page 262) and dividing by
two. ~

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
knowledge and are equipped with
the required tools and replace­
ment parts.
... New tires do not yet have the
optimum adhesion properties.
Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires.
... use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels.
... Do not replace tires individually .
At
least replace both tires on the
same axle at the same time.
Wheel s
... Audi recommends that you use
Audi Original equipment tires. If
you would like to use different
tires, please note that the tires
may perform differently even if
they are the same size¢,&..
... If you would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service
Facility
before making a pur­
chase¢,&..
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
then only use the spare tire* tem­
porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
On all wheel drive vehicles, all
four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds. For this rea­
son, in case of emergency, only
use a spare tire* that is the same ..
