2014 AUDI Q7 tire size

was manufactured. Please see ¢ page 285,
Speed rating (letter code)
for a listing of the
speed rat ing letter codes and the maximum
speed at wh ich the t ires can be driven .
The speed rating letter code (¢
page 2 76) is
on the side wall of the tire
c::> page 284.
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
w inte r tires . This will cause damage to the
tires leading to an acc ident and serious
pe rsonal inj ury to you and yo ur passen­
gers .
A WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can ca use tire fai lure in­
cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
replaced immed iately.
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for
wh ich 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 winte r tires and all-whee l
drive tempt you into taking extra r is k s . A l­
ways remember:
- When bra king, an a ll-wheel drive vehicle
hand les in the same way as a front drive
vehicle.
- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice conditions.

@) For the sake of the env ironment
Use summer tires when weather condi­
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
Snow cha ins may be fitted only to the rear
wheels, and only to certain tire sizes . Ask your
authorized Aud i dealer on which tire sizes
snow chains can be used.
The snow chains must have low-prof ile links
and must not be th icker than 0.53 inch
(13.5 mm) , includ ing the lock .
Remove wheel center covers and trim discs
before putt ing snow cha ins on your vehicle
c::> Q) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are ava il­
able from autho rized Aud i dealers.
A WARNING
Using the wrong snow chains for your vehi­
cle or insta lling them incorrect ly can in­
crease the risk of loss of cont ro l 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 specif ic snow chains.
- Always observe local regulations .
(D Note
-Remove snow chains before dr iv ing o n
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 pos ition of the snow chains after

What you can do to avoid tire and rim
damage
L ow aspect ratio tires can be damaged more
easi ly by impact with potho les, curbs, gu llies
or ridges on the road, particularly if the tire is
underinflated.
I n order 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 air if neces­
sary.
- Drive carefully 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
t ires or have them inspected by the nearest
authorized Aud i dealer . Replace a damaged
t ir e as soon as possible .
- Inspect 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 ich could eventu­
ally cause tire failure. If you be lieve that a
tire may have been damaged, replace the
tire as soon as possible.
- These tires may wea r more quickly than oth­
ers.
- Please also remember that, while these tires
deliver responsive handling, they may ride
less comfortably and make more noise than
other choices .
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes .
The low aspect ratio, ultra high 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 condit ions . If
Tires and wheels 2 91
you drive under those ci rcumstances, you
shou ld equip your vehicle with all-season or
winter tires, which offer better traction under
those conditions. We suggest you use the rec­ ommended snow or all-season t ires specified
for your vehicle, or their equivalent .
Refer to
¢ page 288 for more detailed infor­
mation regarding winter tires .
Tire pressure
monitoring system
ill General notes
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 o n the vehicle placard or tire in­
flat io n pressu re lab el, you sho uld determine
the p roper tire inflation pressure for those
tires).
As an added safe ty feature, your veh icle has
been equipped with a tire pressure monito ring
system ( TPMS) that illuminates a low ti re
pressure telltale when one or more of your
tires is significantly under-inflated. According­
l y, when the low tire pressure te lltale illumi­
nates, you should stop and check your tires as
soon as possible, 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 efficien cy and tire tread life,
and may affect the vehicle's hand ling and
stopping ability .
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
er's responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the leve l to tr igger illumination of the
T PMS low tire pressure tellta le .
Your vehicle has also been eq uipped with a
T PMS ma lfunction indicator to indicate when
the system is not operating properly. The
