G. Tires and Tubes
1. Tires
Bicycle tires are available in many designs and specications, ranging from
general-purpose designs to tires designed to perform best under very specic
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 specic
recommended use, are marked on
the sidewall of the tire (see g. 17).
The part of this information which
is most important to you is Tire
Pressure.
WARNING:Neverinate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
inate a bicycle tire to the correct pressure is with a bicycle pump which has a
built-in pressure gauge.
WARNING: There is a safety risk in using gas station air hoses or
other air compressors. They are not made for bicycle tires. They
move a large volume of air very rapidly, and will raise the pressure in
your tire very rapidly, which could cause the tube to explode.
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. Inating 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 sufciently to pinch
