front or two rear tires (or wheels) as
a pair. Replacing just one tire can
seriously affect your vehicle’s
handling.
• Tires degrade over time, even when they are not being used. Regardless
of the remaining tread, HYUNDAI
recommends that tires 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 tire failure, which
could lead to a loss of vehicle
control resulting in an accident.

WARNING The original tire 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 tire is for emergency
use only. Do not operate your vehicle
over 50 mph (80 km/h) when using
the compact spare tire.

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 tread wear indicators appear. 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.

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.)
245/40R20 99W
245 - Tire width in millimeters.
40 - Aspect ratio. The tire’s section
height as a percentage of its width.
R - Tire construction code (Radial).
20 - Rim diameter in in.
99 - Load Index, a numerical code
associated with the maximum load
the tire can carry.
W - 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:
8.5 X 20
8.5 - Rim width in inches.
J - Rim contour designation.
20 - 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.
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 ones. 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 1523 represents that
the tire was produced in the 15th
week of 2023.
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 lbs. 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.
Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and
maximum section width.
For example:
TREADWEAR 200
TRACTION AATEMPERATURE 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.
WARNING The traction grade assigned to this
tire is based on straight ahead
braking traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction
characteristics.

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 4 psi (28 kPa)
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 75 mph (120 km/h)
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.

if equipped
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 so that they
consequently have increased contact
with the road surface. In some
instances, low aspect ratio tires may
generate more road noise compared
with standard tires.
