If you overfill the tyre, release air by
pushing on the metal stem in the centre
of the tyre valve. Recheck the tyre
pressure with the tyre gauge. Be sure
to put the valve caps back on the valve
stems. Without the valve cap, dirt or
moisture could get into the valve core
and cause air leakage. If a valve cap is
missing, install a new one as soon as
possible.
Tyre rotation
To equalize tread wear, HYUNDAI
recommends that the tyres be rotated
every 10,000 miles (15,000 km) or
sooner if irregular wear develops.
During rotation, check the tyres for
correct balance.
When rotating tyres, check for uneven
wear and damage. Abnormal wear
is usually caused by incorrect tyre
pressure, improper wheel alignment,
out-of-balance wheels, severe braking
or severe cornering. Look for bumps or
bulges in the tread or side of the tyre.
Replace the tyre if you find any of these
conditions. Replace the tyre if fabric or
cord is visible. After rotation, be sure to
bring the front and rear tyre pressures to
specification and check lug nut tightness
(proper torque is 11~13kgf.m (79~94 lbf.
ft, 107~127N.m).

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

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.

Maintenance
Wheel replacement
When replacing the metal wheels for any
reason, make sure the new wheels are
equivalent to the original factory units in
diameter, rim width and offset.
Tyre traction
Tyre traction can be reduced if you drive
on worn tyres, tyres that are improperly
inflated or on slippery road surfaces.
Tyres should be replaced when tread
wear indicators appear. To reduce the
possibility of losing control, slow down
whenever there is rain, snow or ice on
the road.
Tyre maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease tyre
wear. If you find a tyre is worn unevenly,
have your dealer check the wheel
alignment.
When you have new tyres installed,
make sure they are balanced. This will
increase vehicle ride comfort and tyre
life. Additionally, a tyre should always
be rebalanced if it is removed from the
wheel.
Tyre sidewall labelling
This information identifies and describes
the fundamental characteristics of
the tyre and also provides the tyre
identification number (TIN) for safety
standard certification. The TIN can be
used to identify the tyre in case of a
recall.

1. Manufacturer or brand name
Manufacturer or brand name is shown.
2. Tyre size designation
A tyre’s sidewall is marked with a tyre
size designation. You will need this
information when selecting replacement
tyres for your car. The following explains
what the letters and numbers in the tyre
size designation mean.
Example tyre size designation:
(These numbers are provided as an
example only; your tyre size designator
could vary depending on your vehicle.)
185/65R15 88 H
185 - Tyre width in millimeters.
65 - Aspect ratio. The tyre’s section
height as a percentage of its width.
R - Tyre construction code (Radial).
15 - Rim diameter in inches.
88 - Load Index, a numerical code
associated with the maximum load
the tyre can carry.
H - Speed Rating Symbol. See the
speed rating chart in this section for
additional information.

Wheels are also marked with important
information that you need if you ever
have to replace one. The following
explains what the letters and numbers in
the wheel size designation mean.

The chart below lists many of the
different speed ratings currently being
used for passenger vehicle tyres. The
speed rating is part of the tyre size
designation on the sidewall of the tyre.
This symbol corresponds to that tyre’s
designed maximum safe operating
speed.

3. Checking tyre life (TIN : Tyre
Identification Number)
Any tyres that are over six years old,
based on the manufacturing date,
(including the spare tyre) should be
replaced by new ones. You can find
the manufacturing date on the tyre
sidewall (possibly on the inside of
the wheel), displaying the DOT Code.
The DOT Code is a series of numbers
on a tyre consisting of numbers and
English letters. The manufacturing date
is designated by the last four digits
(characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT shows a plant
code number, tyre size and tread pattern
and the last four numbers indicate week
and year manufactured.
For example:
DOT XXXX XXXX 1521 represents that the
tyre was produced in the 15th week of
2021.
4. Tyre ply composition and
material
The number of layers or plies of
rubber-coated fabric in the tyre. Tyre
manufacturers also must indicate the
materials in the tyre, which include steel,
nylon, polyester, and others. The letter
“R” means radial ply construction; the
letter “D“ means diagonal or bias ply
construction; and the letter “B” means
belted-bias ply construction.

The temperature grades are A (the
highest), B and C representing the tyre’s
resistance to the generation of heat
and its ability to dissipate heat when
tested under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause
the material of the tyre to degenerate
and reduce tyre life, and excessive
temperature can lead to sudden tyre
failure. Grades B and A represent higher
levels of performance on the laboratory
test wheel than the minimum required
by law.
WARNING
The temperature grade for this tyre is
established for a tyre that is properly
inflated and not overloaded. Excessive
speed, under-inflation, over-inflation,
or excessive loading, either separately
or in combination, can cause heat
build-up and possible sudden tyre
failure. This may cause loss of vehicle
control resulting in an accident.
Low aspect ratio tyres
Low aspect ratio tyres, the aspect ratio
is lower than 50, are provided for sporty
looks.
Because low aspect ratio tyres are
optimized for handling and braking, their
sidewall is a little stiffer than a standard
tyre. Also, low aspect ratio tyres tend to
be wider so that they consequently have
a greater contact patch with the road
surface. In some instances, they may
generate more road noise compared
with standard tyres.

tyre, the rim of the wheel and the
