2013 AUDI A7 height

@ Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory insta lled rims . If different rims are fit­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
<=> page 291.
.&_ WARNING
Improperly tightened or maintained wheel
bolts can becom e loose caus ing loss of
cont ro l, a co llision and serious persona l in­
Jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clea n so the
w heel bolts can t urn easily and be prop ­
erly t ightened .
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose while d riving if greased or
oi led, even if tightened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Always maintain the co rrect tighten ing
torq ue for the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is moving. If the tightening torque is
too high, the whee l bolts and threads
Tire s an d wheel s 263
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torq ue whee l bolts diago­
nally. After changing a whee l, the torq ue
must be checked as soon as possible with a
torque wrench -preferably by an author­
i zed Audi dealer or qualified workshop.
Low aspect ratio tires
You r Aud i is facto ry-equ ipped w it h low aspect
ra tio tires. These tires have been tho ro ughly
tested and been se lec ted spe cifically for you r
model for their superb perfo rmance, road fee l
and handling under a variety of driving condi­
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or le ss in the tire's s ize
designation. The numera l represents the ratio
of the t ire's sidewa ll height in relation to its
tread width expressed in percentage. Conven­
tiona l tires have a he ight/w idth rat io of 60 or
more .
The performance of low-aspect -ra tio tire s is
particularly sens it iv e to improper inflation
pressure. It is therefore important that low
aspect ratio t ires are inflated to the specified
pre ssure and that the inflation pressur e is
regularly che cked and maintain ed. Tire pre s­
s ures should be checked at least on ce a
m onth and alwa ys before a long trip
¢ page 2 52, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damage d mo re
easily by impact w ith potholes, curbs, g ull ies
or ridges on t he road, partic ularly if the tire is
u nderinflated.
