The best and safest way to inflate a bicycle tyre to the correct pressure is with a bicycle pump which has a built-in
pressure gauge.
Ask your dealer to recommend the best tyre pressure for the kind of riding you will most often do, and have the
dealer inflate your tyres to that pressure. Then, check inflation as described in Section 1.C so you’ll know how
correctly inflated tyres should look and feel when you don’t have access to a gauge. Some tyres 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 tyres have unidirectional treads: their tread pattern is designed to work better in
one direction than in the other. The sidewall marking of a unidirectional tyre will have an arrow showing the correct
rotation direction. If your bike has unidirectional tyres, be sure that they are mounted to rotate in the
correct direction.
4.10 TYRE VALVES
There are primarily two kinds of bicycle tube valves: The Schraeder Valve and the Presta Valve.
The bicycle pump you use must have the fitting appropriate to the valve stems on your bicycle.
All Cooper bikes come fitted with presta valve inner tubes.
