WARNING
To reduce the risk of DEATH or SERIOUS
INJURY:
[ Replace tyres that are worn, show
uneven wear, or are damaged. Worn
tyres can cause loss of braking
effectiveness, steering control, and
traction.
[ Always replace tyres with the same
size as each tyre that was originally
supplied with this vehicle. Using
tyres and wheels other than the
recommended sizes could cause
unusual handling characteristics,
poor vehicle control, or negatively

6 \ V W H P $ % 6 U H V X O W L Q J L Q D V H U L R X V
accident.
[ When replacing tyres (or wheels), it
is recommended to replace the two
front or two rear tyres (or wheels)
as a pair. Replacing just one tyre
can seriously affect your vehicle’s
handling.
[ Tyres degrade over time, even when
they are not being used. Regardless
of the remaining tread, HYUNDAI
recommends that tyres be replaced
after six (6) years of normal service.
[ Heat caused by hot climates or
frequent high loading conditions can
accelerate the aging process. Failure
to follow this warning may cause
sudden tyre failure, which could lead
to a loss of vehicle control resulting
in an accident.
Compact spare tyre replacement
(if equipped)
A compact spare tyre has a shorter
tread life than a regular size tyre.
Replace it when you can see the
tread wear indicator bars on the tyre.
The replacement compact spare tyre
should be the same size and design
tyre as the one provided with your new
vehicle and should be mounted on the
same compact spare tyre wheel. The
compact spare tyre is not designed to
be mounted on a regular size wheel,
and the compact spare tyre wheel is not
designed for mounting a regular size
tyre.
WARNING
The original tyre should be repaired or
replaced as soon as possible to avoid
failure of the spare and loss of vehicle
control resulting in an accident. The
compact spare tyre is for emergency
use only. Do not operate your vehicle
over 50 mph (80 km/h) when using the
compact spare tyre.
