 WARNING
Tire failure may cause loss of 
vehicle control resulting in an 
accident. To reduce risk of SERIOUS 
INJURY or DEATH, take the 
following precautions:
• Inspect your tires monthly for 
proper inflation as well as wear 
and damage.
• The recommended cold tire 
pressure for your vehicle can be 
found in this manual and on the 
tire label located on the driver’s 
side center pillar. Always use a 
tire pressure gauge to measure 
tire pressure. Tires with too 
much or too little pressure wear 
unevenly causing poor handling.
• Check the pressure of the 
spare every time you check the 
pressure of the other tires on 
your vehicle.
• Replace tires that are worn, show 
uneven wear, or are damaged. 
Worn tires can cause loss of 
braking effectiveness, steering 
control, or traction.
• ALWAYS replace tires with the 
same size, type, construction and 
tread pattern 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.
Tire Care
For proper maintenance, safety, and 
maximum fuel economy, you must 
always maintain recommended 
tire inflation pressures and stay 
within the load limits and weight 
distribution recommended for your 
vehicle.
OJX1019024LOJX1019024L
All specifications (sizes and 
pressures) can be found on a label 
attached to the driver’s side center 
pillar.
Recommended Cold Tire 
Inflation Pressures
All tire pressures (including the 
spare) should be checked when the 
tires are cold. “Cold tires” means the 
vehicle has not been driven for at 
least three hours or driven less than 
one mile (1.6 km).
Warm tires normally exceed 
recommended cold tire pressures 
by 4 to 6 psi (28 to 41 kPa). Do not 
release air from warm tires to adjust 
the pressure or the tires will be 
under-inflated. For recommended 
inflation pressure, refer to “Tire and 
Wheels” section in chapter 2.

 WARNING
Recommended pressures must be 
maintained for the best ride, vehicle 
handling, and minimum tire wear.
Over-inflation or under-inflation 
can reduce tire life, adversely 
affect vehicle handling, and lead to 
sudden tire failure that could result 
in loss of vehicle control resulting in 
an accident.
Severe under-inflation can lead 
to severe heat build-up, causing 
blowouts, tread separation and 
other tire failures that can result in 
the loss of vehicle control resulting 
in an accident. This risk is much 
higher on hot days and when 
driving for long periods at high 
speeds.
 CAUTION
• Under-inflation results in 
excessive wear, poor handling 
and reduced fuel economy. 
Wheel deformation is also 
possible. Keep your tire pressures 
at the proper levels. If a tire 
frequently needs refilling, have it 
checked by an authorized retailer 
of Genesis Branded products.
• Over-inflation produces a harsh 
ride, excessive wear at the center 
of the tire tread, and a greater 
possibility of damage from road 
hazards.
Check Tire Inflation Pressure
Check your tires, including the spare 
tire, once a month or more.
How to check
Use a good quality tire pressure 
gauge to check tire pressure. You 
can not tell if your tires are properly 
inflated simply by looking at them. 
Radial tires may look properly 
inflated when they are under-
inflated.
Remove the valve cap from the tire 
valve stem. Press the tire gauge 
firmly onto the valve to get a 
pressure measurement. If the cold 
tire inflation pressure matches the 
recommended pressure on the tire 
and loading information label, no 
further adjustment is necessary. If 
the pressure is low, add air until you 
reach the recommended pressure. 
Make sure to put the valve caps 
back on the valve stems. Without 
the valve cap, dirt or moisture could 
get into the valve core and cause 
air leakage. If a valve cap is missing, 
install a new one as soon as possible.
If you overfill the tire, release air by 
pushing on the metal stem in the 
center of the tire valve. Recheck the 
tire pressure with the tire gauge. Be 
sure to put the valve caps back on 
the valve stems. Without the valve 
cap, dirt or moisture could get into 
the valve core and cause air leakage. 
If a valve cap is missing, install a new 
one as soon as possible.

Tire Rotation
To equalize tread wear, Genesis 
Branded Vehicle recommends that 
the tires be rotated according to the 
maintenance schedule or sooner if 
irregular wear develops.
During rotation, check the tires for 
correct balance.
When rotating tires, check for 
uneven wear and damage. Abnormal 
wear is usually caused by incorrect 
tire pressure, improper wheel 
alignment, out-of-balance wheels, 
severe braking or severe cornering. 
Look for bumps or bulges in the 
tread or side of the tire. Replace 
the tire if you find any of these 
conditions. Replace the tire if fabric 
or cord is visible. After rotation, be 
sure to bring the front and rear tire 
pressures to specification and check 
wheel bolt tightness (proper torque 
is 101~116 lbf.ft [14~16 kgf.m]).
OHI078078OHI078078
Disc brake pads should be inspected 
for wear whenever tires are rotated.
 Information
The outside and inside of the 
unsymmetrical tire is distinguishable. 
When installing an unsymmetrical 
tire, be sure to install the side marked 
“outside” face the outside. If the side 
marked “inside” is installed on the 
outside, it will have a negative effect 
on vehicle performance.
 WARNING
• Do not use the compact spare 
tire for tire rotation.
• 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.

Wheel Alignment and Tire 
Balance
The wheels on your vehicle were 
aligned and balanced carefully at the 
factory to give you the longest tire 
life and best overall performance.
In most cases, you will not need to 
have your wheels aligned again. 
However, if you notice unusual tire 
wear or your vehicle pulling one way 
or the other, the alignment may need 
to be reset.
If you notice your vehicle vibrating 
when driving on a smooth road, your 
wheels may need to be rebalanced.
NOTICE
Incorrect wheel weights can 
damage your vehicle’s aluminum 
wheels. Use only approved wheel 
weights.
Tire Replacement
Tread wear indicatorTread wear indicator
OHI078080OHI078080
If the tire is worn evenly, a tread wear 
indicator will appear as a solid band 
across the tread. This shows there is 
less than 1/16 inch (1.6 mm) of tread 
left on the tire. Replace the tire when 
this happens.
Do not wait for the band to appear 
across the entire tread before 
replacing the tire.
 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, Genesis Branded Vehicle 
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 compact spare 
tire 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 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 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 1520 represents that 
the tire was produced in the 15th 
week of 2020.
4. Genesis exclusive tire
Genesis Branded Vehicle 
recommends that tires designed 
specifically for Genesis vehicles 
be used. You may find the marking 
“GOE” (Genesis Original Equipment) 
embossed on the tire sidewall.
5. 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.

6. 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.
7. 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.
8. 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 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.   
Page 579 of 632

Maintenance
9-38
Temperature - A, B & C
The temperature grades are A (the 
highest), B and C representing the 
tire’s resistance to the generation 
of heat and its ability to dissipate 
heat when tested under controlled 
conditions on a specified indoor 
laboratory test wheel.
Sustained high temperature can 
cause the material of the tire to 
degenerate and reduce tire life, 
and excessive temperature can 
lead to sudden tire failure. Grades 
B and A represent higher levels of 
performance on the laboratory test 
wheel than the minimum required 
by law.
 WARNING
The temperature grade for this tire is 
established for a tire that is properly 
inflated and not overloaded. 
Excessive speed, under-inflation, 
over-inflation, or excessive loading, 
either separately or in combination, 
can cause heat build-up and 
possible sudden tire failure. This 
may cause loss of vehicle control 
resulting in an accident.
