Check Tyre Inflation Pressure; Tyre Rotation - Hyundai i30 N Owner's Manual

Maintenance
CAUTION
•
Under-inflation results
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation is also
possible. Keep your tyre pres-
sures at the proper levels. If a
tyre frequently needs refilling,
we recommend it be checked
by a HYUNDAI authorised
repairer.
•
Over-inflation produces
harsh ride, excessive wear at
the centre of the tyre tread,
and a greater possibility of
damage from road hazards.

Check tyre inflation pressure

Check your tyres, including the spare
tyre, once a month or more.

How to check
Use a good quality tyre pressure
gauge to check tyre pressure. You
can not tell if your tyres are properly
inflated simply by looking at them.
Radial tyres may look properly inflat-
ed when they are under-inflated.
Remove the valve cap from the tyre
a
valve stem. Press the tyre gauge
firmly onto the valve to get a pres-
sure measurement. If the cold tyre
inflation pressure matches the rec-
ommended pressure on the tyre and
loading information label, no further
adjustment is necessary. If the pres-
sure 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 tyre, release air by
pushing on the metal stem in the
centre of the tyre valve.
Recheck the tyre pressure with the
tyre gauge. Be sure to put the valve
caps back on the valve stems.
Without the valve cap, dirt or mois-
ture could get into the valve core and
cause air leakage. If a valve cap is
missing, install a new one as soon as
possible.

Tyre rotation

To equalize tread wear, HYUNDAI
recommends that the tyres be rotat-
ed every 7,500 miles (12,000 km) or
sooner if irregular wear develops.
During rotation, check the tyres for
correct balance.
When rotating tyres, check for
uneven wear and damage. Abnormal
wear is usually caused by incorrect
tyre pressure, improper wheel align-
ment, out-of-balance wheels, severe
braking or severe cornering. Look for
bumps or bulges in the tread or side
of the tyre. Replace the tyre if you find
any of these conditions. Replace the
tyre if fabric or cord is visible. After
rotation, be sure to bring the front and
rear tyre pressures to specification
and check lug nut tightness (proper
torque is 11~13 kgf·m [79~94 lbf·ft]).
