12. Tyres
12.1 Maintenance
It is recommended that tyre pressures are checked
regularly. Well-inflated tyres generate much less rolling
resistance than underinflated tyres, which means less effort
when cycling. What is more, your bike will respond better to
your steering and braking input. Furthermore, underinflated
tyres wear faster and are more liable to get punctures. The
rim can also wear more rapidly if your tyre pressure is too
low.
If you are able to press your thumbs into your tyres just
a little, it means that they have enough air in them. If you
have a bicycle pump with a pressure gauge, then you can
read the recommended pressure off the tyre sidewall. The
tyres on an ordinary bike need to be inflated to between
3.5 and 6 bar. The exact recommended tyre pressure is
shown on your tyre sidewall.
If you are not using your Gazelle for an extended period,
during the winter for instance, it can have an adverse effect
on your tyres.
Check the tread on your tyres regularly. If the tread is
almost gone, or you can see the canvas in places, the tyre
will need replacing. In addition, is you see small cracks in
the tyre or get punctures significantly more often, it means
you are due for a new tyre. In chapter 12.2, you will read
how to take the tyre off the wheel. You need to take the
wheel off to replace the tyre; chapter 11.3 explains how to
do this.
12.2 Repairs
If you have a flat tyre check first whether the valve has
failed. Do this by wetting the valve opening a little; if any
bubbles appear, then the valve is leaking. Check first
whether the problem can be remedied by cleaning the
valve. If this doesn’t help, then you need to replace the
valve.
