PaRt i
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.
CaUtion
Pencil type automotive tire gauges can be
inaccurate and should not be relied upon for
consistent, accurate pressure readings. Instead,
use a high quality dial gauge.
Ask your dealer to recommend the best tire pressure
for the kind of riding you will most often do, and have
the dealer inflate your tires to that pressure. Then,
check inflation as described in SECTION 1.C so you’ll
know how correctly inflated tires should look and feel
when you don’t have access to a gauge. Some tires
may need to be brought up to pressure every week
or two. So, it is important to check your tire pressures
before every ride.
Some special high-performance tires have
unidirectional treads: their tread pattern is designed
to work better in one direction than in the other. The
sidewall marking of a unidirectional tire will have an
arrow showing the correct rotation direction. If your
bike has unidirectional tires, be sure that they are
mounted to rotate in the correct direction.
