Maintenance

 WARNING
Recommended pressures must be 
maintained for the best ride, vehicle 
handling, and minimum tyre wear.
Over-inflation or under-inflation 
can reduce tyre life, adversely affect 
vehicle handling, and lead to sudden 
tyre 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 tyre 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 tyre pressures at 
the proper levels. If a tyre frequently 
needs refilling, we recommend it be 
checked by an authorised Retailer of 
Genesis Branded Products.
•  Over-inflation produces a 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 inflated when they are under-
inflated.
Remove the valve cap from the tyre valve 
stem. Press the tyre gauge firmly onto 
the valve to get a pressure measurement. 
If the cold tyre inflation pressure 
matches the recommended pressure on 
the tyre 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 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 
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.
