WARNING
To reduce the risk of DEATH or SERIOUS
INJURY:
[ Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of braking
effectiveness, steering control, and
traction.
[ Always replace tires with the same
size as each tire that was originally
supplied with this vehicle. Using
tires and wheels other than the
recommended sizes could cause
unusual handling characteristics,
poor vehicle control, or negatively
affect your vehicle’s Anti-Lock Brake
System (ABS) resulting in a serious
accident.
[ When replacing tires (or wheels), it
is recommended to replace the two
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.
Compact spare tire replacement
(if equipped)
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the tread
wear indicator bars on the tire. The
replacement compact spare tire should
be the same size and design tire as the
one provided with your new vehicle
and should be mounted on the same
compact spare tire wheel. The compact
spare tire is not designed to be mounted
on a regular size wheel, and the compact
spare tire wheel is not designed for
mounting a regular size tire.
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.

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.
