Operation Manual

1) Bike manufacturers recommend the optimum tire pressure for their bike models.
They may recommend different tire pressure for front and rear tires so please
follow the recommendation in the bike user manual. These recommended
pressures usually meant for comfort riding and optimum performance of the bike.
It is not advisable to go below the recommended pressure level.
2) The bike manufacturer recommended tire pressure is “cold pressure”. When you
ride your bike to the gas station, the friction on the road will heat up your bike
tires within a few minutes. Typically there will 1 psi (~7kPa) increase in air
pressure for every 10 deg F (5.6 deg C) rise in temperature, and vice versa for
decrease in air pressure. It is advisable to inflate the tire pressure with this
compensated pressure above the recommended pressure.
3) Air pressure in tires is affected by changes in temperature. Check and adjust your
tire pressure whenever there is a drastic change in environment temperature, eg.
change of seasons.
4) A tire will normally lose its pressure through natural causes unless accelerated by
a puncture, faulty valve or damaged wheels. It is advisable to change the tire
valves or at least check the valves condition every time you change a new set of
tires. Under normal condition, a set of tires could deflate at a rate of up to 2psi per
month. It is good practice to check your tire pressure regularly and top up to the
optimum pressure.
5) Every bike tire has a maximum inflation pressure. It is not advisable to inflate to
the maximum inflation pressure of the tire. Follow the bike manufacturer‟s
recommended tire pressure instead.
