2013 AUDI A5 COUPE brake

248 Tires and wheels
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer ­
tain roads, this normally also applies to
vehicles with all wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory installed 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 fitted
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 275.
.&_ WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious persona l in­
Jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose while driving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
- Always maintain the correct tightening
torque for the wheel bolts 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 veh i- cle
is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bolts
diagonally . After changing a wheel, the
torque must be checked as soon as possi­
ble with a torque wrench -preferably by an
authorized Audi dealer or qualified work­
shop.
Low aspect ratio tires
Your Audi is factory -equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road feel
and handling under a variety of driving condi­
t ions . Ask your authorized Audi dealer for
more details .
The low aspect ratio of these tires is indicated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven­
tional tires have a height/w idth rat io of 60 or
more.
The performance of low-aspect-ratio tires is
particularly sensitive to improper inflation
pressure. 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 pres­
sures should be checked at least once a
month and always before a long trip
¢ page 237, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact with potholes, curbs, gul lies
or ridges on the road, particularly if the tire is
underinflated . ..,.

has been designed specifically for your type of
vehicle.
It must not be swapped with a com­
pact spare t ire from another type of veh icle .
Snow cha ins
F or techn ica l reasons, the use of snow chains
on the compact spare tire is
not p ermitt ed .
If you do have to dr ive with snow cha ins and a
front tire fails, mou nt the spare whee l w it h
tire ins tead of a rea r tir e. Install the snow
chains on the rear t ire and use it to replace
the defective front tire .
A WARNING
-Never use the spare tire if it is damaged
or if it is worn down to the tread wear in ­
dicators.
- If the spare tire is mo re than 6 years o ld,
use it only in an emergency and w ith ex­
treme caution and careful driving.
- The spare tire is intended only for tem­
porary and short-term use. It should be
replaced as soon as possib le w ith the
normal wheel and t ire .
- After mounting the compact spare tire,
the tire pressure must be checked as
soon as poss ible. The tire pressure of the
compact spa re tire must be 4.2 bar ; oth­
erwise, you risk hav ing an accident.
- Do not drive faster than SO mph (80 km/
h). You risk having an acc ident .
-Avo id full-throttle acce lerat ion, heavy
braking, and fast corner ing . You risk hav­
ing an acc ident.
- Never drive us ing more t han one spare
wheel and tire . You risk hav ing an acci­
de nt.
- No rma l summer or winte r tires must not
be mounted on the compact spare whee l
rim.
- For technical reasons, the use of ti re
ch ains on the spare tire is no t permitted.
If it is necess ary to dr ive wi th tire ch ain s,
the spare whee l must be moun ted on the
front axle in the event o f a flat in a rear
t ire. The newly ava ilable front w heel
must then be installed in place of the

rea r whee l w ith the flat tire. Installing
the t ire cha in be fore mounting the whee l
and tire is recommended.
- Loose items in the passenger compart­
ment can cause serious personal injury
during hard brak ing or in a n accident.
Never store the inflatable spa re tire or
jack and tools in the passenge r compart­
ment.
