2023 HYUNDAI ELANTRA tire pressure

Maintenance9-40
Temperature A, B & C
The temperature grades are A (the
highes
t), 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. Grade C responds
to a level of performance which
all passenger car tires must meet
under the Federal Motor Vehicle
Safety Standard No. 109. 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.
Tire Terminology and Definitions
Air Pressure
The amount of air inside the tire
pressing outward on the tire. Air
pressure is expressed in pounds per
square inch (psi) or kilopascal (kPa).
Accessory Weight
This means the combined weight
of optional accessories. Some
examples of optional accessories
are automatic transmission, power
seats, and air conditioning.
Aspect Ratio
The relationship of a tire’s height to
its width.
Belt
A rubber coated layer of cords that
is located between the plies and the
tread. Cords may be made from steel
or other reinforcing materials.
Bead
The tire bead contains steel wires
wrapped by steel cords that hold the
tire onto the rim.
Bias Ply Tire
A pneumatic tire in which the plies
are laid at alternate angles less than
90 degrees to the centerline of the
tread.
Cold Tire Pressure
The amount of air pressure in a tire,
measured in pounds per square inch
(psi) or kilopascals (kPa) before a tire
has built up heat from driving.

vehicle with standard and optional
equipment including the maximum
capacity of fuel, oil and coolant, but
without passengers and cargo.
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

Sidewall
The portion of a tire between the
tread and the bead.
Speed Rating
An alphanumeric code assigned to a
tire indicating the maximum speed
at which a tire can operate.
Traction
The friction between the tire and
the road surface. The amount of grip
provided. Tread
The portion of a tire that comes into
contact with the road.
Treadwear Indicators
Narrow bands, sometimes called
“wear bars”, that show across the
tread of a tire when only 1/16 inch of
tread remains.
UTQGS
Uniform Tire Quality Grading
Standards is a tire information
system that provides consumers
with ratings for a tire’s traction,
temperature and treadwear.
Ratings are determined by tire
manufacturers using government
testing procedures. The ratings are
molded into the sidewall of the tire.
Vehicle Capacity Weight
The number of designated seating
positions multiplied by 150 lbs. (68
kg) plus the rated cargo and luggage

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.

Maintenance9-44
CAUTION

[ It is not easy to recognize tire
damage with your own eyes. But
if there is the slightest hint of tire
damage, have the tire checked
or replaced because the tire
damage may cause air leakage
from the tire.

[ If the tire is damaged by driving
on a rough road, off road,
pothole, manhole, or curb stone,
it will not be covered by the
warranty.
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 and
consequently have a greater contact
patch with the road surface. In some
instances they may generate more
road noise compared with standard
tires.
CAUTION
Because the sidewall of a low
aspect ratio tire is shorter than
a standard tire, the rim of the
wheel and the tire itself is more
easily susceptible to damage. Use
caution when driving and follow the
guidelines below to help minimize
damage to the wheel and tire:

[When driving on a rough road
or off road, drive cautiously
because tires and wheels may
be damaged. And after driving,
inspect tires and wheels.

[ When passing over a pothole,
speed bump, manhole, or curb
stone, drive slowly so that
the tires and wheels are not
damaged.

[ If the tire is subjected to a severe
impact, have the tire and wheel
inspected by an authorized
HYUNDAI dealer.

[ Inspect the tire condition and
pressure every 1,800 miles
(3,000km).
