Bicycle tires are available in many designs and specifications, ranging from general-purpose designs to tires designed to

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 specific recommended use, are marked on the sidewall of

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 way to inflate a bicycle tire to the correct pressure is with a bicycle pump.

avoid over-inflation when using a gas station air hose, put air into your tire in short, spaced bursts.
Tire pressure is given either as maximum pressure or as a pressure range. How a tire performs under different terrain or

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.
