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.
Tire Traction
Tire traction can be reduced if you drive
on worn tires, tires that are improperly
inflated or on slippery road surfaces.
Tires should be replaced when the tread
depth is at least 1.6 mm (2/32 inch). To
reduce the possibility of losing control,
slow down whenever there is rain, snow
or ice on the road.
Tire Maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease tire
wear. If you find a tire is worn unevenly,
have your dealer check the wheel
alignment.
When you have new tires installed,
make sure they are balanced. This will
increase vehicle ride comfort and tire
life. Additionally, a tire should always
be rebalanced if it is removed from the wheel.
Tire Sidewall Labeling
This information identifies and describes
the fundamental characteristics of
the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be
used to identify the tire in case of a
recall.

1. Manufacturer or brand name
Manufacturer or brand name is shown.
2. Tire size designation
A tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replacement
tires for your car. The following explains
what the letters and numbers in the tire
size designation mean.
Example tire size designation:
(These numbers are provided as an
example only; your tire size designator
could vary depending on your vehicle.) 205/65R16 95H
205 - Tire width in millimeters.
65 - Aspect ratio. The tire’s section height as a percentage of its width.
R - Tire construction code (Radial).
16 - Rim diameter in inches.
95 - Load Index, a numerical code associated with the maximum load
the tire can carry.
H - Speed Rating Symbol. See the speed rating chart in this section for
additional information.

Wheel size designation
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.
Example wheel size designation:6.5J X 16
6.5 - Rim width in inches.
J - Rim contour designation.
16 - Rim diameter in inches.
Tire speed ratings
The chart below lists many of the
different speed ratings currently being
used for passenger vehicle tires. The
speed rating is part of the tire size
designation on the sidewall of the tire.
This symbol corresponds to that tire’s
designed maximum safe operating speed.
Speed Rating Symbol Maximum Speed
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph)
V 240 km/h (149 mph)
W 270 km/h (168 mph) Y 300 km/h (186 mph) 3. Checking tire life (TIN : Tire
Identification Number)
Any tires that are over six years old,
based on the manufacturing date,
(including the spare tire) should be
replaced by new tires. You can find the
manufacturing date on the tire sidewall
(possibly on the inside of the wheel),
displaying the DOT Code. The DOT Code
is a series of numbers on a tire 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, tire size and tread pattern
and the last four numbers indicate week
and year manufactured.
For example:
DOT XXXX XXXX 1421 represents that the
tire was produced in the 14th week of 2021.
4. Tire ply composition and material
The number of layers or plies of
rubber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, 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.

5. Maximum permissible inflation
pressure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer to
the Tire 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 tire. When replacing the
tires on the vehicle, always use a tire that
has the same load rating as the factory
installed tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section width.
For example:TREAD WEAR 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one-and-a-half times (1½) as well
on the government course as a tire
graded 100.
The relative performance of tires 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 tires. The
tires 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 tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor traction
performance.

All Season Tires
HYUNDAI specifies all season tires
on some models to provide good
performance for use all year round,
including snowy and icy road conditions.
All season tires are identified by ALL
SEASON and/or M+S (Mud and Snow) on
the tire sidewall. Snow tires have better
snow traction than all season tires and
may be more appropriate in some areas.
Summer Tires
HYUNDAI specifies summer tires on
some models to provide superior
performance on dry roads. Summer tire
performance is substantially reduced in
snow and ice. Summer tires do not have
the tire traction rating M+S (Mud and
Snow) on the tire side wall. If you plan
to operate your vehicle in snowy or icy
conditions, HYUNDAI recommends the
use of snow tires or all season tires on all
four wheels.
Snow Tires
If you equip your car with snow tires,
they should be the same size and have the same load capacity as the original
tires. Snow tires should be installed on
all four wheels; otherwise, poor handling
may result. Snow tires should carry 28
kPa (4 psi) more air pressure than the
pressure recommended for the standard
tires on the tire label on the driver’s
side of the center pillar, or up to the
maximum pressure shown on the tire
sidewall, whichever is less. Do not drive
faster than 120 km/h (75 mph) when your
vehicle is equipped with snow tires.
Radial-Ply Tires
Radial-ply tires provide improved tread
life, road hazard resistance and smoother
high speed ride. The radial-ply tires used
on this vehicle are of belted construction,
and are selected to complement the
ride and handling characteristics of your
vehicle.
Radial-ply tires have the same load
carrying capacity, as bias-ply or bias
belted tires of the same size, and use the
same recommended inflation pressure.
Mixing of radial-ply tires with bias-ply or
bias belted tires is not recommended.
Any combinations of radial-ply and bias-
ply or bias belted tires when used on the
same vehicle will seriously deteriorate
vehicle handling. The best rule to follow
is: Identical pairs of radial-ply tires
should always be used as a set for the
front tires and a set for the rear tires.
Longer wearing tires can be more
susceptible to irregular tread wear. It is
very important to follow the tire rotation
interval in this chapter to achieve the
tread life potential of these tires. Cuts
and punctures in radial-ply tires are
repairable only in the tread area, because
of sidewall flexing. Consult your tire
dealer for radial-ply tire repairs.
WARNING
Do not mix bias ply and radial ply tires
under any circumstances. This may
cause unusual handling characteristics
that may cause loss of vehicle control
resulting in an accident.

Low Aspect Ratio Tires
The aspect ratio is lower than 50 on low
aspect ratio tires.
Because low aspect ratio tires are
optimized for handling and braking, their
sidewall is a little stiffer than a standard
tire. Also low aspect ratio tires tend to be
wider and consequently have a greater
contact patch with the road surface. In
some instances they may generate more
road noise compared with standard tires.
CAUTION
Because the sidewall of a low aspect
ratio tire is shorter than a standard tire,
the rim of the wheel and the tire itself
is more easily susceptible to damage.
Use caution when driving and follow
the guidelines below to help minimize
damage to the wheel and tire: • When driving on a rough road or
off road, drive cautiously because
tires and wheels may be damaged.
And after driving, inspect tires and wheels.
• When passing over a pothole, speed
bump, manhole, or curb stone, drive
slowly so that the tires and wheels
are not damaged.
• If the tire is subjected to a severe
impact, have the tire and wheel
inspected by an authorized HYUNDAI
dealer.
• Inspect the tire condition and
pressure every 3,000km (1,800
miles).
CAUTION
• It is not easy to recognize tire
damage with your own eyes. But
if there is the slightest hint of tire
damage, have the tire checked or
replaced because the tire damage
may cause air leakage from the tire.
• If the tire is damaged by driving
on a rough road, off road, pothole,
manhole, or curb stone, it will not be
covered by the warranty.
