Example tire size designation:
(These numbers are provided as an
example only; your tire size designator
could vary depending on your vehicle.)
235/40R19 96Y
235 - Tire width in millimeters.
40 - Aspect ratio. The tire’s section height as a percentage of its width.
R - Tire construction code (Radial).
19 - Rim diameter in inches.
96 - Load Index, a numerical code associated with the maximum load
the tire can carry.
Y - Speed Rating Symbol. See the speed rating chart in this section for
additional information.
Wheel size designation
Wheels are also marked with important
inf
ormation 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:
8.0J x 19
8.0 - Rim width in inches.
J - Rim contour designation.
19 - Rim diameter in inches. Tire speed ratings
The chart below lists many of the
diff
erent 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 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)
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 1521 represents that the
tire was produced in the 15th 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:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
Tr e a d w e a r
The tread wear grade is a comparative
r
ating 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.

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
pounds (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.
Passenger (P-Metric) tire
A tire used on passenger cars and some
light duty trucks and multipurpose
vehicles.
Ply
A layer of rubber-coated parallel cords.

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 headlamp assembly to get to the
bulb(s).
Removing/installing the headlamp
assembly can result in damage to the
vehicle.
WARNING
[ Prior to working on a light, depress
the foot brake, shift to P (Park), apply
the parking brake, press the Engine
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.
NOTICE
Be sure to replace the burned-out bulb
with one of the same wattage rating.
Otherwise, it may cause damage to the
fuse or electrical wiring system.
NOTICE
To prevent damage, do not clean the
headlamp lens with chemical solvents
or strong detergents.
Information
The headlamp and tail lamp lenses could
appear frosty if the vehicle is washed after
driving or the vehicle is driven at night in
wet weather. This condition is caused by
temperature difference between the lamp
inside and outside and, it does not indicate
a problem with your vehicle. When
moisture condenses in the lamp, it will be
removed after driving with the headlamp
on. The removable level may differ
depending on lamp size, lamp position
and environmental condition. However, if
moisture is not removed, have your vehicle
inspected by an authorized HYUNDAI
dealer.
