2016 Seat Mii wheel size

The essentials
Tyres with compulsory direction of ro-
t ation A directional tread pattern can be identified
by
the arr
ows on the sidewall that point in
the direction of rotation. Always observe the
direction of rotation indicated when fitting
the wheel to guarantee optimum properties
of this type of tyres with regard to grip,
noises, wear and aquaplaning.
If it is absolutely necessary to fit the spare
tyre* against the direction of rotation, drive
with care as this means the tyre does not of-
fer optimum driving properties. This is of par-
ticular importance when the road surface is
wet.
To return to directional tread tires, replace
the punctured tyre as soon as possible and
restore the obligatory direction of rotation of
all tyres.

● Store the spare wheel, the temporary spare
wheel or the ch
anged wheel securely in the
luggage compartment. ●
Have the tightenin
g torque of the wheel
bolts checked as soon as possible with a tor-
que wrench ››› page 38.
● Have the flat tyre replaced as quickly as
poss
ible.
Snow chains Use When using snow chains, applicable local
l
e
gi

slation and maximum permitted speed
limits must be observed.
In winter weather, snow chains not only help
to improve grip but also improve the braking
capacity.
The fitting of chains is permitted only on
front wheels and with the following combi-
nations of wheel trims and tyres :

165/70 R145 J x 14 offset of 35175/65 R14 SEAT recommends you ask a technical serv-
ic
e f
or f

urther information on wheel, tyre and
chain sizes.
Wherever possible use fine-link chains meas-
uring less than 15 mm including the lock. Remove wheel hub covers and trim rings be-
fore fittin

g snow chains ››› . The wheel bolts
shou l
d be c
overed with caps for safety rea-
sons. These are available from technical serv-
ices.
Temporary spare wheel
For technical reasons, snow chains must not
be used on the compact temporary spare
wheel ›››
 page 206.
If it is necessary to fit chains with the tempo-
rary spare wheel in use, install the wheel on
the rear axle in the event of a fault in a front
wheel. Then, fit the rear wheel that is free, in-
stead of the damaged front wheel. In this sit-
uation, observe the rotating direction of the
wheels. SEAT recommends attaching the
snow chains before fitting the wheel. WARNING
The use of unsuitable or incorrectly fitted
ch ain

s could lead to serious accidents and
damage.
● Always the appropriate snow chains.
● Observe the fitting instructions provided by
the snow c
hain manufacturer.
● Never exceed the maximum permitted
speeds
when driving with snow chains. » 41

The essentials
CAUTION
● Remo v
e the snow chains to drive on roads
without snow. Otherwise they will impair
vehicle handling, damage the tyres and wear
out very quickly.
● Wheel rims may be damaged or scratched if
the chain
s come into direct contact with
them. SEAT recommends the use of covered
snow chains. Note
Snow chains are available in different sizes
acc or

ding to the vehicle type. Emergency towing of the vehi-

Screw the front towline anchorage into the
screw connection ››› Fig. 58 and tighten it
with the wheel brace.
Tow rope or tow bar
When towing, the tow bar is the safest and
vehicle friendly way. You should only use a
tow rope if you do not have a tow bar. A tow rope should be slightly elastic to avoid
damag

e to both vehicles. It is advisable to
use a tow rope made of synthetic fibre or sim-
ilarly elastic material.
● Only secure the tow rope or tow bar to the
towline anc
horage or specially designed fit-
ting.
Notes for the driver of the towed vehicle
● Keep the ignition running to prevent the
steerin
g wheel from locking and also to allow
the use of the turn signals, horn, windscreen
wipers and washers.
● As the power assisted steering does not
work if
the engine is not running, you will
need more strength to steer than normally.
● The brake must be depressed much harder
as the br
ake servo does not operate. Avoid
hitting the towing vehicle.
● Note the instructions and information con-
tained in the Ins
truction Manual for the vehi-
cle to be towed.
Notes for the driver of the towing vehicle
● Accelerate gently and carefully. Avoid sud-
den manoeuvr
es.
● Brake well in advance than usual and brake
gently.
● Not

e the instructions and information con-
tained in the In s

truction Manual for the vehi-
cle to be towed. 42

Introduction SEAT recommend that all work on tyres and
wheels
i

s carried out by a specialised work-
shop. These workshops have the necessary
special tools and replacement parts, trained
personnel and facilities for disposing of the
old tyres while respecting the environment.
SEAT recommends taking your car in for tech-
nical service. WARNING
The vehicle cannot be totally controlled or
brak ed if

the tyres (new or used) are worn or
damaged.
● Incorrect use of wheels and tyres could
make driv
ing more dangerous and result in
serious accidents and damage.
● All four wheels must be fitted with radial
tyre
s of the same type, size (rolling circumfer-
ence) and the same tread pattern.
● New tyres do not give maximum grip and
wil
l not have reached their maximum braking
capacity to start with, and therefore need
running in. To prevent accidents and major
damage, extreme caution should be taken for
the first 600 km. ●
Check ty

re pressures regularly and ensure
they are maintained at the pressures indica-
ted. If the tyre pressure is too low, they could
overheat, resulting in tread detachment or
even burst tyres.
● Never drive on damaged (punctured, cut,
crac
ked or dented) or worn tyres. Driving on
damaged or worn tyres could result in burst
tyres, serious accidents or damage. Worn or
damaged tyres must be replaced immediate-
ly.
● Never exceed the maximum permitted
speed or loa
ds specified for the type of tyre
fitted on your vehicle.
● The effectiveness of driver and brake assist
syst
ems also depends on the grip of the
tyres.
● If you notice unusual vibration or if the ve-
hicle p
ulls to one side when driving, stop the
car immediately and check the tyres and
wheels for damage.
● To minimise the risk of losing control of the
vehicl
e or causing a serious accident, never
undo the bolted joints of beadlock wheels.
● Never mount used tyres or wheels if you are
not sur
e of their previous history. They may
be damaged, although the damage is not im-
mediately visible.
● Old tyres, even if they have never been
used, ma
y lose air or burst unexpectedly
while driving, especially at high speeds, re-
sulting in serious accident and injury. If tyres
are over six years old, they should only be » 199

Advice
WARNING
The use of worn or damaged wheel rims could
mak e driv
ing more dangerous and result in
serious accidents and damage.
● Only wheel rims which have been approved
for use w
ith your vehicle should be used.
● Inspect wheel rims regularly for damage
and repl
ace as required. WARNING
If the bolted joints of wheel rims with bolted
ring trims ar

e not correctly tightened or loos-
ened, this could result in serious accident.
● Never loosen the bolted joints of wheel
rims with bo
lted ring trims.
● Any work relating to wheel rims with bolted
rims shoul
d be carried out at specialised
workshop. SEAT recommends taking your car
in for technical service. Note
A SEAT Service Centre should be consulted to
find out whether wheel s

or tyres of different
sizes to those originally fitted by SEAT can be
fitted, and to find out about the combinations
allowed between the front axle (axle 1) and
the rear axle (axle 2). Replacement of wheel rims and new

● All four wheels must be fitted with radial
tyr e

s of the same type, size (rolling circumfer-
ence) and the same tread pattern.
● The tread depth of new tyres may vary, ac-
cor din

g to the type and make of tyre and the
tread pattern.
Replacing tyres
● Where possible, always replace both
wheels on an ax
le (both wheels on the front
axle or both wheels on the rear axle) ››› .
● Only replace used tyres with those author-
i sed b
y

SEAT for the corresponding type vehi-
cle. Pay special attention to size, diameter,
and maximum load and speed capacity.
● Never use tyres which are larger than SEAT
appro
ved tyres. If the tyres are too big, they
may knock or rub against the chassis or other
components, resulting in damage. WARNING
New tyres do not give maximum grip and will
not h av

e reached their maximum braking ca-
pacity to start with, and therefore need run-
ning in.
● To prevent accidents and major damage,
extreme c
aution should be taken for the first
600 km. WARNING
There should be adequate space between the
tyr e

s and the vehicle in accordance with the
vehicle design. If this is not the case, the
tyres may rub against parts of the running
gear, chassis or brake lines, leading to faults
in the brake system or to tread detachment,
and the risk of burst tyres.
● The true tyre dimension should not be
great
er than the dimensions of tyres manu-
factured and approved by SEAT and should
not rub against parts of the vehicle. Note
Although tyres may be shown as being the
same s iz

e, the true dimensions of different
types of tyre may vary with respect to the
nominal size, or tread patterns may be differ-
ent. Note
If you use tyres that are approved by SEAT,

Tyres with directional tread pattern
Tyres with directional tread pattern have
been designed to operate best when rotating
in only one direction. An arrow on the tyre
sidewall indicates the direction of rotation on
tyres with directional tread. Always observe
the direction of rotation indicated when
mounting the wheel. This guarantees opti-
mum grip and helps to avoid aquaplaning,
grip, noise and wear.

ains may be fitted only to the front
wheels.
Consult the section “wheels” of this manual.
Wheel bolts
After the wheels have been changed, the
tightening torque of the wheel bolts should
be checked as soon as possible with a torque
wrench ››› . The tightening torque for steel
and al lo
y

wheels is 140 Nm. WARNING
● Check the ty

re pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds.
● If the tightening torque of the wheel bolts
is t
oo low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. Note
We recommend that you ask your Technical
Serv ic

e for information about appropriate
wheel, tyre and snow chain size. 212
