2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 256, fig. 190.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex­
ample, if the "XXX" amount
equals 1400 lbs and there will
be five 150 lbs passengers in
your vehicle, the amount of available cargo and luggage
load capacity is 650 lbs
(1400-750 (5
X 150) = 650 lbs)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex­ ceed the available cargo and luggage load capacity calculat­
ed in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your ve-
260
hicle. Consult this manual to
determine how this reduces
the available cargo and lug­
gage load capacity of your vehi­
cle.
~check the tire sidewall
(¢ page 246, fig. 188) to deter­
mine the designated load rating
for a specific tire.
· Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them
¢ &..
_8. WARNING
-Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi­
cation, see
¢ page 2 78, Finishing.
- Always keep the wheel bolts and the threads in the wheel hub clean and free of
grease .
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility . Never repair or disassemble
rims yourself, because this increases the risk
of an accident .
Winter tires

handling when driving in winter conditions . Be-
cause of their construction (width, compound, ..,.

Wheels
The low aspect ratio of these tires is i ndicated by
a numeral of
55 or less in the tire's si ze designa­
tion. The numera l rep resents the rat io o f the
tire's sidewall he ight in relat ion to its tread width
expressed in percentage . Conventional tires have
a height/w idt h rat io of 60 o r more.
The performance of low -aspect-ratio tire s is par ·
ticularly sensitive to improper inflation pres­
sure.
It i s therefore important that low aspect
ratio tires ar e inflat ed to the specifi ed pr essure
and that the inflation pre ssure is regularly
checked and maintained . Tire pre ssure s should
be checked at le ast once a month and always
before a long trip¢
page 256.
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi­
ly by impact wi th potholes, cu rbs, g ullies or
ridges on the road, pa rt ic ul arly if the tire is un­
derinflated .
I n order to minim ize t he oc currence of impac t
d a mage to the t ires of your ve hicle, we recom ­
mend that you ob5erve the following precau­
tions:
- Always mai nta in recommended inf lation pres ­
s ur es . Che ck your tire p ress ure every 2,000
miles (3, 000 km) and ad d air if necessary .
- Drive caref ully on roads with potho les, deep
gull ies or r idges . The im pact from d riving
th rough or ove r su ch obs tacles can damage
your tires. Impact with a curb may also cause
damage to your tires.
-A fter any impact, immediately inspect your
ti res or have them inspected by the nearest au ­
thori zed Audi dea ler. Replace a damaged tire as
soon as possib le.
- Inspect yo ur 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 cou ld eventually cause
ti re failure . If you believe that a tire may have
been damaged, re place the t ire as soon as pos­
s ible.
- T hese tires may wear more qu ick ly than othe rs .
- Please a lso remember t hat, w hile these tires
deliver responsive handling, they may r ide less
262
comforta bly and make more noise than o ther
choices .
Reduced performance in winter/cold season
condition s
All tires are des igned for certain purposes . The
l ow aspect ratio , ultra h igh performance tires
o rigina lly installed on your vehicle are intended
for maximum d ry and wet road perfo rmance and
handling. They a re not suitable for co ld, snowy or
i cy weather conditions . If you drive under those
c ircumstances, you should equip you r vehicle
with all-season o r winter tires, which offer better
t ra ct ion unde r th ose condi tio ns. We suggest yo u
u se the recommen ded snow or a ll-season tires
spe cified for your vehicle, o r th e ir equiv alent.

t ion regard ing winter tires.
Uniform tire quality grading
- Tr ea d wea r
- Tr actio n AA ABC
- T empe ratu re ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
max imum section width
¢ page 246, fig . 188.
For example : Tread wear 200 , Traction AA , Tem­
perature
A .
All passenge r ca r tir es must conform to Federal
Safety Req uirements in a ddition to these grades.
Tread wear
The tread wear grade is a compa rative rating
based on the wea r ra te o f the tire w hen tested
u nder con trolled cond itions on a specified gov ­
ernment test course .
Fo r example, a tire g raded 150 wou ld wea r one
a n d one half (1 1/2) times as well o n the govern ­
ment cou rse as a t ire graded 100.
The re lative pe rformance of tires depends upon
t h e ac tual cond itions of the ir use, however, and
m ay dep art significan tly from the no rm due to
variations in driv ing habi ts, service pract ices and
diffe rences in road characteristics and climate. ..,.

Techn ical data
- Exceeding permissible weight ratings can
res ult in vehicle damage, accidents and per­
sonal injury.
(D Note
- The vehi cle capacity weig ht figures apply
when the load is d istributed evenly in the
vehicle (passengers and luggage) . When
transport ing a heavy load in the luggage
compartment, carry the load as near to the
rear axle as possib le so that the veh icle's
hand ling is not impaired .
- Do not exceed the maximum perm iss ible
ax le loads or the maximum g ross ve hicle
we igh t. Always remember that the veh icle's
han dling will be affe cted by the extra load.
Th erefore, adjust your spee d accordingly.
