destroyed .
A WARNING
Using incorrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acc i
dent .
(D Note
Snow chains can damage the rims/wheel cov
ers * if the chains come into d irect contact
w ith them. Remove the wheel covers* first .
Use coated snow chains.
(D Tips
When using snow cha ins, it may be useful to

Low aspect ratio tires
Your Aud i is factory -equipped with low aspect ra
tio tires. These t ires have been tho roughly tested
a nd been se lected specifically fo r yo ur model fo r
thei r supe rb per fo rman ce , road feel and handling
un der a va riety of d riving conditions . As k yo ur au
thor ized Audi dealer for mo re details .
T he low aspect ratio of these t ires is in dicated by
a nume ral of
55 or less in the tire's size desig na
tion . The numera l rep resents the rat io o f th e
tire's sidewall he ight in relat ion to its tread width
expressed in pe rcentage. Conventional tires have
a height/w idt h rat io o f 60 o r more .
The performance of low-aspect -ra tio tires i s par
ticularly sensitive to improper inflation pres
sure . It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained . Tire pressures should
be checked at least once a month and always
before a long trip <=>
page 244.
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi
ly by impact with potholes, cu rbs, gullies or
250
ridges on the road, particularly if the tire is un
derinflated.
I n orde r to mi nimize the occur rence o f imp act
dam age to the tires o f yo ur vehicle, we recom
mend that you observe the following preca u
tions:
- Always m aintain reco mmende d in fla tion pres
sures. Check yo ur tir e pressure eve ry 2,0 00
m iles (3,00 0 km) and add air if necessary .
- Dr ive c arefully on ro ads w ith potholes, deep
gu llies o r ridges . The impact from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso ca use
damage to your t ires.
- After any impact, immediate ly inspect you r
tires or have them inspected by the nearest au
thorized Aud i dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear . Damage is not always
easy to see . Damage can lead to loss of a ir and
unde rinflation, w hich could event ua lly cause
tire fa ilure . If you believe that a tire may have
be en damaged, replace the tire as soon as pos
sible .
- These tires may wear mo re quickly than o thers .
- Please also remember that, while these tires delive r responsive hand ling, they may ride less
comfortab ly and make mo re noise than o ther
choi ces.
Reduced performance in winter/cold season
conditions
A ll tires are des igned for certain purposes. The
l ow aspect ratio, ultra h igh performance tires
