2015 AUDI RS5 CABRIOLET rims

234 Tires and wheels
Maximum Permissible
Inflation Pressure
This number is the greatest
amount of air pressure that
should ever be put in the tire
under normal driving condi­
tions.
.&_ WARNING
-Using incorrect or unmatch­ ed tires and/ or wheels or improper tire and wheel
combinations can lead to loss of control, collision and
serious personal injury.
-Always use tires, rims and wheel bolts that meet the
specifications of original
factory-installed tires or
other combinations that have been specifically ap­
proved by the vehicle manu­
facturer.
-Tires age even if they are
not being used and can fail
suddenly, especially at high
speeds. Tires that are more
than 6 years old can only be used in an emergency and
then with special care and
at lower speeds.
-Never mount used tires on your vehicle if you are not sure of their "previous
histo­
ry." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
failure and loss of vehicle
control.
-All four wheels must be fit­ ted with radial tires of the
same type, size (rolling cir­
cumference) and the same
tread pattern. Driving with different tires reduces vehi­
cle handling and can lead to
a loss of control.
-If the replacement tire is
not the same as the tires
that are mounted on the ve­
hicle -for example with win­
ter tires - only use the re­
placement tire for a short
period of time and drive
with extra care. Refit the normal road wheel as soon
as safely possible.
-Never drive faster than the maximum speed for which
the tires on your vehicle are
rated because tires that are
driven faster than their rat-
ed speed can fail suddenly. ...

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
struct ions provided by the snow chain
manufacturer .
- When driving with snow chains never
dr ive faster than the speed permitted for
your specific snow cha ins.
- Always observe local regulat ions .
- Remove snow cha ins before driving on
roads not covered with snow to avoid
damaging t ires and wear ing the snow
chains down unnecessar ily .
- Snow chains, wh ic h come into d irect con­
tact with the wheel rim, can scratch or
damage it . Therefore, make sure that the
snow chains are suitab ly covered . Check
the position of the snow chains after
driv ing a few yards and correct if neces­
sary. Follow the i nstr uctions from the
snow chain manufacturer when doing so.
(D Tips
Where s now cha ins a re mandatory oncer­
tain roads, this norma lly also applies to
vehicles with all wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
corr ect torque.
The design of whee l bolts is ma tched to the
factory insta lled r ims. If d ifferent rims are fit­
ted, the correct wheel bo lts with the r ight
l ength and correctly shaped bolt heads must
be used . This ensures that wheels are fitted
secu re ly and that the b rake system functions
correctly . In certain circumstances, you may not use
whee l bolts from a different vehicle -even if it
is the same mode l¢
page 266 .
A WARNING "--
Improperly t ightened or ma inta ined whee l
bo lts can become loose causing loss of
control, a col lision and serious pe rsonal i n­
jury .
- Always keep the wheel bo lts and the
threads in the wheel hubs clean so the
wheel bo lts can turn easily and be prop­
erly tightened.
- Never g rease or oil the wheel bolts and
the threads in the wheel hubs. They can become loose while driv ing if g reased o r
oiled, even if t igh tened to the specified
torque.
- On ly use wheel bolts that belong to the
rim being installed .
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct t ightening
torque for the wheel bolts to reduce the
risk of a wheel loss. If the tighten ing tor­
que of the whee l bolts is too low, they
can loosen and come out when the vehi­
cle is moving. If the tightening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
Q) 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 to rque wrenc h - preferably by an
autho rized Audi dea le r or qualified wor k­
shop .
Low aspect ratio tires

ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road fee l ..,.

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction.
Using a replacement tire with a tre ad
patte rn intend ed for us e in a specific
directi on
When us ing a replacement t ire with a tread
pattern intended for use in a specific direc­
tion, please note the fo llowing:
- T he direction of rotation is marked by an
ar ­
row on th e side of the tire.
- If the replacement tire has to be installed in
t h e incorrect d irection, use the tire only
temporarily since the tire will no t be able to
achieve its optimum performance character­
istics with regard to aquaplaning, noise and
wear .
- We recommend that you pay particular at­
tention to this fact during wet weather and
that you adjust your speed to match road conditions.
- Replace the flat tire with a new one and
have it installed on your veh icle as soon as
poss ible to restore the handling advantages
of a unid irect ional tire.
