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.
Speed Rating

S 112 mph (180 km/h) T 118 mph (190 km/h)
H 130 mph (210 km/h) V 149 mph (240 km/h)
W 168 mph (270 km/h) Y 186 mph (300 km/h)

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.

DOT markings
A code molded into the sidewall of a
tire signifying that the tire is in
compliance with the U.S. Department
of Transportation motor vehicle
safety standards. The DOT code
includes the Tire Identification
Number (TIN), an alphanumeric
designator which can also identify
the tire manufacturer, production
plant, brand and date of production.
GVWR
Gross Vehicle Weight Rating
GAWR FRT
Gross Axle Weight Rating for the
Front Axle.
GAWR RR
Gross Axle Weight Rating for the Rear
axle.
Intended outboard sidewall
The side of an asymmetrical tire, that
must always face outward when
mounted on a vehicle.
Kilopascal (kPa)
The metric unit for air pressure.
Light Truck (LT) tire
A tire designated by its manufacturer
as primarily intended for use on
lightweight trucks or multipurpose
passenger vehicles.
Load ratings
The maximum load that a tire is rated
to carry for a given inflation pressure.Load index
An assigned number ranging from 1 to
279 that corresponds to the load
carrying capacity of a tire.
Maximum inflation pressure
The maximum air pressure to which a
cold tire may be inflated. The
maximum air pressure is molded onto
the sidewall.
Maximum load rating
The load rating for a tire at the
maximum permissible inflation
pressure for that tire.
Maximum loaded vehicle weight
The sum of curb weight; accessory
weight; vehicle capacity weight; and
production options weight.
Normal occupant weight
The number of occupants a vehicle is
designed to seat multiplied by 150
lbs. (68 kg).
Occupant distribution
Designated seating positions.
Outward facing sidewall
An asymmetrical tire has a particular
side that faces outward when
mounted on a vehicle. The outward
facing sidewall bears white lettering
or bears manufacturer, brand, and/or
model name molding that is higher or
deeper than the same moldings on
the inner facing sidewall.

Light Bulbs
Consult an authorized HYUNDAI dealer to
replace most vehicle light bulbs. It is
difficult to replace vehicle light bulbs
because other parts of the vehicle must
be removed before you can get to the
bulb. This is especially true for removing
the headlight assembly to get to the
bulb(s).
Removing/installing the headlight
assembly can result in damage to the
vehicle.
WARNING • Prior to replacing a light bulb, depress the brake pedal, shift to P (Park), apply
the parking brake, press the Start/Stop
button to the OFF position, and take the
key with you when leaving the vehicle
to avoid sudden movement of the
vehicle and to prevent possible electric
shock.
• Be aware the bulbs may be hot and may burn your fingers.

Information Headlight desiccant
This vehicle is equipped with desiccant to
reduce fogging inside the headlight due to
moisture. The desiccant is consumable and its performance may change based on the used
period or environment. If fogging inside the
headlight due to moisture continues for a long
time, contact an authorized HYUNDAI
dealer.
Information The headlight and tail light lenses could
appear to have condensation inside if the
vehicle is washed after driving or if the
vehicle is driven in wet weather. This
condition is caused by a higher temperature
inside the light and a cooler outside
temperature. Moisture that condenses in the
light is removed after driving with the light
on. If the moisture is not removed, contact an
authorized HYUNDAI dealer.
Information • A normally functioning light may flicker
momentarily to stabilize the vehicle’s
electrical control system. However, if the
light goes out after flickering momentarily,
or continues to flicker, have the system
inspected by an authorized HYUNDAI
dealer.
• The parking light may not turn on when the parking light switch is turned on, but the
parking light and headlight switch may turn
on when the headlight switch is turned on.
This may be caused by network failure or
vehicle electrical control system
malfunction. If this occurs, contact an
authorized HYUNDAI dealer.
Information Adjust the headlight aim after an accident or
the headlight is replaced.
