D.5 TIRES AND TUBES
WARNING!
Some bicycles intended for competition are fitted with tires that
are glued on to specially made rims. These are called "sew-up"
or "tubular" tires. Properly mounting these tires requires
specialized knowledge and skills. Ask your dealer to teach you
how to mount tubulars before you attempt it on your own. An
incorrectly installed tubular tire can come off the rim, causing
you to lose control and fall.
D.5.1 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, customer service
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
(Figure 4.15). The part of this information which is most important
to you is Tire Pressure. But some wheel rim manufacturers also
specify maximum tire pressure with a label on the rim.

WARNING!
Never inflate a tire beyond the maximum pressure marked on
the tire's sidewall or the wheel rim. If the maximum pressure
rating for the wheel rim is lower than the maximum pressure
shown on the tire, always use the lower rating. Exceeding the
recommended maximum pressure may blow the tire off the rim
or damage the wheel rim, which could cause damage to the bike
and injury to the rider and bystanders.
