Tires
Bicycle tires are available in many designs and specifications, ranging from general-purpose designs to tires
designed to perform best under very specific weather or terrain conditions. If, once you’ve gained
experience with your new bike, you feel that a different tire might better suit your riding needs, your
dealer can help you select the most appropriate design.
The size, pressure rating, and on some high-performance tires the specific recommended use, are marked
on the sidewall of the tire .The part of this information which is most important to you is Tire Pressure.
WARNING: Never inflate a tire beyond the maximum pressure marked on the tire’s sidewall. Exceeding
the recommended maximum pressure may blow the tire off the rim, which could cause damage to the
bike and injury to the rider and bystanders.
The best and safest way to inflate a bicycle tire to the correct pressure is with a bicycle pump which has a
built-in pressure gauge.
Tire pressure is given either as maximum pressure or as a pressure range. How a tire performs under
different terrain or weather conditions depends largely on tire pressure. Inflating the tire to near its
maximum recommended pressure gives the lowest rolling resistance; but also produces the harshest ride.
High pressures work best on smooth, dry pavement. Very low pressures, at the bottom of the
recommended pressure range, give the best performance on smooth, slick terrain such as hard-packed
clay, and on deep, loose surfaces such as deep, dry sand.
Tire pressure that is too low for your weight and the riding conditions can cause a puncture of the tube by
allowing the tire to deform sufficiently to pinch the inner tube between the rim and the riding surface.
Tire Valves
The tire valve allows air to enter the tire’s inner tube under pressure, but doesn’t let it back out unless you
want it to. There are primarily two kinds of bicycle tube valves used in Australia: the Schraeder Valve and
the Presta Valve. The bicycle pump you use must have the fitting appropriate to the valve stems on your
tire.
The tires use a Schraeder valve, which is like the valve on a car tire. To inflate a Schraeder valve tube,
remove the valve cap and push the air hose or pump fitting onto the end of the valve stem. To let air out of
a Schraeder valve, depress the pin in the end of the valve stem with the end of a key or other appropriate
object.
1. Check whether rim is deflected or loosened and whether spoke is loosened or broken before riding. If any
unusual condition, ask professional technician for adjustment or change.
2. Please change the tyre if cover tyre grain is worn and torn.
3. Please guarantee proper PSI. When inflating, please take nominal value of cover tyre as reference. Never
inflate over the pressure or under the pressure.
Caution: Please make sure the contact area of tyre and ground should not be less than 10cm while riding.
