Tyre care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tyre
inflation pressures and stay within the
load limits and weight distribution rec-
ommended for your vehicle.
All specifications (sizes and pressures)
can be found on a label attached to the
driver’s side centre pillar. (Continued)Replace tyres that are worn,
show uneven wear, or are dam-
aged. Worn tyres can cause
loss of braking effectiveness,
steering control, or 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 rec-
ommended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle’s Anti-Lock Brake System
(ABS) resulting in a serious
accident.
Tyre failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
Inspect your tyres monthly for
proper inflation as well as
wear and damage.
The recommended cold tyre
pressure for your vehicle can
be found in this manual and on
the tyre label located on the
driver’s side centre pillar.
Always use a tyre pressure
gauge to measure tyre pres-
sure. Tyres with too much or
too little pressure wear
unevenly causing poor han-
dling.
Check the pressure of the
spare every time you check
the pressure of the other tyres
on your vehicle.

Maintenance
Recommended cold tyre infla-
tion pressures
All tyre pressures (including the
spare) should be checked when the
tyres are cold. “Cold tyres” means
the vehicle has not been driven for at
least three hours or driven less than
1.6 km.
Warm tyres normally exceed recom-
mended cold tyre pressures by 28 to
41 kPa (4 to 6 psi). Do not release air
from warm tyres to adjust the pres-
sure or the tyres will be under-inflat-
ed. For recommended inflation pres-
sure, refer to “Tyre and Wheels” in
chapter 8.Recommended pressures must
be maintained for the best ride,
vehicle handling, and minimum
tyre wear.
Over-inflation or under-inflation
can reduce tyre life, adversely
affect vehicle handling, and
lead to sudden tyre failure that
could result in loss of vehicle
control resulting in an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tyre failures that can
result in the loss of vehicle con-
trol resulting in an accident.
This risk is much higher on hot
days and when driving for long
periods at high speeds.
WARNING
Under-inflation results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation is also
possible. Keep your tyre pres-
sures at the proper levels. If a
tyre frequently needs refilling,
we recommend it be checked
by an authorised HYUNDAI
dealer.
Over-inflation produces a
harsh ride, excessive wear at
the centre of the tyre tread,
and a greater possibility of
damage from road hazards.

Maintenance
Check tyre inflation pressure
Check your tyres, including the spare
tyre, once a month or more.
How to check
Use a good quality tyre pressure
gauge to check tyre pressure. You
can not tell if your tyres are properly
inflated simply by looking at them.
Radial tyres may look properly inflat-
ed when they are under-inflated.
Remove the valve cap from the tyre
valve stem. Press the tyre gauge
firmly onto the valve to get a pres-
sure measurement. If the cold tyre
inflation pressure matches the rec-
ommended pressure on the tyre and
loading information label, no further
adjustment is necessary. If the pres-
sure is low, add air until you reach
the recommended pressure. Make
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.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 equalise tread wear, HYUNDAI
recommends that the tyres be rotat-
ed every 10,000 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 pres-
sure, 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
11~13 kgf·m).

4. Tyre ply composition and
material
The number of layers or plies of rub-
ber-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 con-
struction; the letter "D“ means diago-
nal or bias ply construction; and the
letter "B" means restrained-bias ply
construction.
5. Maximum permissible infla-
tion pressure
This number is the greatest amount
of air pressure that should be put in
the tyre. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tyre and Loading Information
label for recommended inflation
pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tyre. When
replacing the tyres on the vehicle,
always use a tyre that has the same
load rating as the factory installed
tyre.
7. Uniform tyre quality grading
Quality grades can be found where
applicable on the tyre sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREAD WEAR 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tyre when tested under controlled
conditions on a specified government
test course. For example, a tyre grad-
ed 150 would wear one-and-a-half
times (1½) as well on the government
course as a tyre graded 100.The relative performance of tyres
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate.
These grades are molded on the
sidewalls of passenger vehicle tyres.
The tyres available as standard or
optional equipment on your vehicle
may vary with respect to grade.
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tyre’s ability to
stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tyre marked C
may have poor traction performance.

Maintenance
Because the sidewall of a low
aspect ratio tyre is shorter than
a standard tyre, the rim of the
wheel and the tyre itself is more
easily susceptible to damage.
Use caution when driving and
follow the guidelines below to
help minimise damage to the
wheel and tyre:
When driving on a rough road
or driving off a road, be careful
not to damage the tyres and
wheels. After driving, inspect
the tyres and wheels.
When passing over a pothole,
speed bump, manhole, or curb
stone, drive the vehicle slowly
so as not to damage the tyres
and wheels.
(Continued)
CAUTION(Continued)
If the tyre is subjected to a
severe impact, we recom-
mend you have the tyre and
wheel inspected by an autho-
rised HYUNDAI dealer.
Inspect the tyre condition and
pressure every 3,000 km to
prevent tyre damage.
It is not easy to recognise tyre
damage with your own eyes.
But if there is the slightest hint
of tyre damage, have the tyre
checked or replaced because
the tyre damage may cause air
leakage from the tyre.
If the tyre is damaged by driv-
ing on a rough road, off road,
pothole, manhole, or curb
stone, it will not be covered by
the warranty.
