2018 AUDI Q3 bolt pattern

Wheels
differently even if they are the
same size
c::> .,&..
~ If you would like to equip your
vehicle with a tire/rim combina­ tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur­
chase
c::> ,& .
If the spare tire is different from
the regular tires installed on the
vehicle - for example, if winter
tires or wide tires are installed -
then only use the spare tire tem­ porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
Applies to: vehicles with all wheel
drive: all four wheels must be
equipped with tires that are the
same brand and have the same
construction and tread pattern so
that the drive system is not dam­
aged by different wheel speeds. For this reason, in case of emer­
gency, only use a spare tire that has the same circumference as
the regular tires.

A WARNING -
-Only use tire/rim combina­ tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more than six years old when abso­
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when ...

and a special procedure. You must not repair or
disassemble them ¢.&. .
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an acc ident. For the correct tightening specifi ­
cation, see ¢
page 192, After changing a
wheel .
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of grease.
- Only use wheel bo lts that fit the rim .
- Always have damaged r ims repa ired by an
authorized Audi dealer o r autho rized Aud i
Service Facility . Never repair or d isassemble
r ims yourself, because this inc reases the risk
of an accident.
Winter tires
W inte r ti res s ignificantly improve the vehicle's
h andling when driving in win ter condit ions . Be­
cause of the ir constr uction (width, compound,
tread pattern), summer tires provide less trac­
tion on ice and snow .
... Use w inter t ires on all fo ur wheels .
... Only use winter t ires that are approve d for your
v ehicl e.
... Please note that the maximum permitted
speed may be lower with winter tires¢.&.

The effec tiveness of winter tires is reduced great­
l y when the t read is worn down to a depth of
0 .1 57 in ( 4 mm). The char acter istics of win ter
tires a lso dec rease great ly as t he tire ages, re­
gardless of the remaining tread .

... Note the maximum permitted spee d when dr iv­
ing with snow chains . Do not exceed 30 mph
(SO km/h).
U se fine-me sh snow chains . They must no t add
more than 0.53 inch (13. S mm) in height, incl ud­

Use of snow c hains is only permitted with certa in
r im/tire comb inat io ns due to technical reasons .
C heck wi th an au thorized Audi dea ler or author­
ized Audi Service Facility to see if you may use
snow chains .
A WARNING
Using incor rect snow chains or installing snow
cha ins incor rect ly can resu lt in loss of veh icle
control, which increases the risk of an acci·
dent.

Emergency assistance
& WARNING
You or your passengers could be injured while changing a wheel if you do not follow these
safety precautions :
- If you have a flat ti re, move a safe d ista nee
off the road . Turn off the engine, turn the
emergency flashers on and use other warn·
ing devices to alert other motorists.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the jack,
always fully set the parking brake and block
the front and back of the wheel diagonally
opposite the wheel being changed with the
folding chocks or other objects. When one
front wheel is lifted off the ground, placing
the Automatic Transmission in "P" (Park)
will
not prevent the vehicle from moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary, use a
sturdy board under the jack .
- Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com­
partment
