Foreign objects inserted in the tyre
Do not remove foreign bodies if they have
●
penetrated through the tyre wall!
If the vehicle comes with a tyre mobility
●
system, where necessary seal the damaged
tyre as shown in section
specialised workshop for repair or replace-
ment. SEAT recommends visiting a SEAT
dealership for this.
The sealant at the lower part of the tyre tread
wraps around the foreign body and provision-
ally seals the tyre.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on single drive tyres. Al-
ways note the direction of rotation indicated
when mounting the wheel. This makes sure
that optimal use is made of tyre properties in
terms of aquaplaning, grip, excessive noise
and wear.
Subsequent fitting of accessories
If you wish to change or fit wheels, rims or
wheel trims, we recommend that you consult
with a SEAT Official Service centre for advice
regarding current techniques.

WARNING
New tyres do not have maximum grip dur-
●
ing the first 500 km. Drive particularly
carefully to avoid possible accidents.
Never drive with damaged tyres. This
●
may cause an accident.
If you notice unusual vibrations or if the
●
vehicle pulls to one side when driving, stop
Practical tips
the vehicle immediately and check the
tyres.
Never use old tyres or those with an un-
●
known history of use.
New wheels and tyres
It is best to have all wheels and tyres serviced
by a specialised workshop. There they have
the required knowledge, the special tools and
the corresponding spare parts.
Even winter tyres lose their grip on ice. If you
●
have installed new tyres, drive the first 500
km carefully and at a moderate speed.
All four wheels must be fitted with tyres of
●
the same type, size (rolling circumference)
and, if possible, tread pattern.
When changing tyres, do not change just
●
one; change at least two on the same axle.
If you want to equip your vehicle with a
●
combination tyres and rims that are different
to those fitted in the factory, inform your spe-
cialised workshop before purchasing them

The sizes of the rims and tyres approved for
your vehicle are listed in the vehicle docu-
mentation (e.g. EC Certificate of Conformity
