Ask your dealer to recommend the best tire pressure for the kind of riding you will most often do, and have
the dealer infate your tires to that pressure. Then, check infation as described in “Mechanical safety check”
so you’ll know how correctly infated 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 import ant to check your tire
pressures before every ride.
Some special high-performance tires stem. 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.
TIRE VALVES
There are primarily two kinds of bicycle tube valves: The Schrader Valve and the Presta Valve. The bicycle
pump you use must have the ftting appropriate to the valve stems on your bicycle.
The Schrader valve (fg. 4-12 ) is like the valve on a car tire. To infate a Schrader valve tube,
remove the valve cap and clamp the pump ftting onto the end of the valve stem. To let air out
of a Schrader valve, ‚““Hlji depress the pin in the end of the valve stem with the end of a key
or other appropriate object.
The Presta valve (fg. 4-13 ) has a narrower diameter and is only found on bicycle tires. To
infate a Presta valve tube using a Presta headed bicycle pump, remove mm the valve cap;
unscrew (counter-clockwise) the valve stem lock nut; and push down on the valve stem to
free it up. Then push the pump head on to the valve head, and infate. To infate a Presta valve
