Tyres & Inner Tubes - Whyte 905 Instruction Manual

◊ ◊ ◊ ◊ Riding in wet weather may increase the braking distance by up
to 60%. Ride slower & apply the brakes earlier.
◊ Disc brakes can get extremely hot with extended use. Be careful
not to touch a disc brake until it has cooled.
◊ If replacing worn or damaged parts, use only manufacturer-
approved genuine replacement parts.
Tyres & Inner Tubes
Tyre Inflation
Inflate your tyres to within the air pressure recommended on the tyre sidewalls (for
an example, see figure 18). When inflating a tyre, consider the weight of the rider
and any load being carried. Higher
pressure usually gives the best
performance on road surfaces (for
speed), while lower pressure works
best for off-road riding (for grip).
WARNING: Never inflate a tyre above the maximum pressure
marked on the tyre's sidewall. Exceeding the recommended
maximum pressure may blow the tyre 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 tyre to the correct pressure is with a
bicycle pump which has a built-in pressure gauge, available from your Whyte dealer.
WARNING: There is a safety risk in using air compressors that
are intended for motor vehicle tyres. These move a large
volume of air very rapidly, which could cause the tube to
explode.
WARNING: A tyre pressure that is too low can allow the tyre
to deform sufficiently and pinch the inner tube, possibly split-
ting it. The subsequent deflation may be rapid, possibly
causing you to lose control and fall.
For regular riding most tyres may need to be brought up to pressure every week or
two. If the bike is being stored for a long time, preserve the tyres by deflating to
the minimum pressure shown on the sidewall and keep them away from sunlight.
CAUTION: Always check your tyre pressures before every ride.
Replacing Tyres
Tyres are available in many different types. Having ridden your new bike or having
worn out the tyres, if you feel that a different tyre might better suit your riding
needs, your Whyte dealer can help you select the most appropriate replacements.
WARNING: There are two reason why you must replace a
