Cannondale Chase Series Owner's Manual page 36

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 .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.
Some special high-performance
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.
