wheel size AUDI A7 2012 User Guide

The speed rating letter code (c::> page 233) is
on the side wall of the tire
c::> page 242 .
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off. Never drive faster
than the speed permitted for your specific
winter tires . This will cause damage to the
tires leading to an accident and serious
personal injury to you and your passen­
gers.
A WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire failure in­ cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
replaced immediately.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated .
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks . Al­
ways remember :
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@l For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.

Tires and wheels
Snow chains
Snow chains may be fitted only to the front
wheels , and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch
(10,S mm) , including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
c::> (]) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
A WARNING ,..__
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions provided by the snow chain manufacturer .
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains .
- Always observe local regulations.
(D Note
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so. ..,.

In o rder to minimize the occurrence o f impact
damage to the tires of your vehicle, we recom­ mend that you observe the following precau­
tions :
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add a ir if neces­
sary.
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires .
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer . Replace a damaged
t ire as soon as poss ible .
- In spect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of
air and unde rinflation, wh ic h could eventu­
ally cause ti re fail ure.
If yo u be lieve that a
ti re may have been damaged , replace the
tire as soon as possible.
- These tires may wear more quick ly than oth ­
ers.
- Please a lso remembe r that, whi le these t ires
deliver respons ive handling, they may ride
less comfortably and make more noise than
other c hoices.
Reduced p erformance in winter /cold
s ea son condit ion s
All ti res are designed for certain purposes .
The low aspect ratio, ultra hig h performance
tires originally installed on your veh icle are in­
tended for max imum dry and wet road per­
formance and handling . They are not suitable
for cold, snowy or icy weather cond it ions . If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, whi ch offe r better traction under
those cond it ions . We suggest you use the rec­
ommended snow or all -season tires specified
for your ve hicle, or their equiva lent .

Tire pressure
monitoring system
ill General notes
App lies to vehicles : wi th tire p ress ure mo nito rin g system
Each tire, incl uding the spare (if provided),
shou ld be checked monthly when co ld and in ­
flated to the inflation pressure recommended
by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a d ifferent size than the
s iz e indicated on the vehicle placard or tire in­
flat io n pressu re labe l, you shou ld dete rmine
the p roper t ire inflation p ress ure fo r those
t i r es).
As an added safety feature, your veh icle has
been equipped with a tire pressure monitoring
system ( TPMS) that illum inates a low ti re
pressure te lltale whe n one or more o f your
ti res is significant ly under -inflated . According­
ly, when the low tire pressure te lltale i llumi­
nates, you shou ld stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly un­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under-inflation al­
so reduces fuel effic iency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing abil ity.
Please note that the TPMS is not a subst itute
fo r proper tire ma intenanc e, and it is the d riv­
er's respo nsibility to maintain co rrect tire
pressure, even if under-inflation has not
reached the leve l to tr igger illum inat ion of the
T PMS low ti re p ressu re tellta le .
You r vehicle has also been equipped with a
T PMS ma lf u nction indicator to ind icate w hen
the sys tem is not operating prope rly . T he
T PMS ma lfunction indicator is combined w ith
the low tire pressure te lltale. When the sys ­
tem detects a malfunction, the telltale wi ll
flash for approximate ly one min ute and then
rema in con tinuously i llum inated . T hi s se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunct ion exists . ..,.
