Check Tire Inflation Pressure - Hyundai Elantra 2024 Owner's Manual

Maintenance
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 may result
in loss of vehicle control resulting in
a collision.
• Severe under-inflation may lead to
severe heat build-up, causing
blowouts, tread separation, and
other tire failures that result in loss
of vehicle control resulting in a
collision. This risk is much higher on
hot days and when driving for a
long time at high speeds.
• Under-inflation may cause
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 inspected by an
authorized HYUNDAI dealer.
• 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, at least once a month.
How to check
Use a good quality tire pressure
gauge to check the tire pressure. You
cannot 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 it
reaches the recommended pressure.
Be sure to put the valve caps back on
the valve stems. Without the valve
cap, dirt or moisture may 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 may get into the
valve core and cause air leakage. If a
valve cap is missing, install a new one
as soon as possible.
