Tyres
There are lots of di erent kinds of tyres.
Their properties and their rolling resistance
depends on their profile.
Do not exceed the stipulated inflation
pressure for the tyre. If you do, the tyre
could burst.
Pump air into the tyre to achieve at least the
recommended minimum inflation pressure.
If the pressure is too low, the tyre could
come away from the rim.
The maximum and minimum inflation
pressures are usually indicated on the side
of the tyre.
When changing tyres, only use the same
kind of tyre, with the same dimensions
and the same profile. Using di erent tyres
may have a negative e ect on the handling
characteristics of your bike. This will
potentially result in an accident.
Tyres are subject to wear. Check the tread,
pressure and condition of the sides of your
tyres regularly. Replace worn tyres before
using your bike.
Make sure you respect the dimensions
of the fitted tyre. They are indicated by
standardised references.
•
Example 1: "46-622" indicates that
the width of the tyre is 46mm and the
diameter of the rim is 622mm
•
Example 2: "28 x 1.6 inches" indicates that
the diameter of the tyre is 28 inches and
the width is 1.6 inches.
