12. INFLATING Your TYRES
Before riding your bicycle, you must
inflate your tyre up to the correct
pressure. There are two kinds of
bicycle tube valves in common use: the
Schraeder (Car) Valve and the Presta
Valve (also known as a French Valve).
Identify which valve you have and follow
the appropriate instructions below to
inflate your tyres.
A Presta valve has a narrower diameter and is only found on
bicycle tyres. To inflate a Presta valve using a Presta headed
bicycle pump:
•
Remove the valve cap
•
Unscrew the valve stem lock nut
•
Push down on the valve stem to free it up
•
Push the pump head on to the valve head and inflate to the
PSI or KPA value written on the sidewall of your tyre. (Refer
to page 43 of your bicycle owner’s manual for a KPI to PSI
conversion table.)
•
The Schraeder valve is like the valve on a car tyre. To Inflate a
Schrader valve tube:
•
Remove the valve cap and push the pump head on to the valve
stem.
•
Inflate to the PSI or KPA value written on the sidewall of your
tyre. (Refer to page 43 of your bicycle owner’s manual for a
KPI to PSI conversion table.)
