Practical advice
General Information / Safety Information
Tyre condition
Before setting off, check the tyres on the
bus for:
external signs of damage
foreign objects in the tyre tread
foreign objects between twin tyres
cracks, bulges
Note:
Please note that cracks, bulges or extern-
al damage can cause a tyre to burst. This
could result in you losing control of the
bus and causing an accident, thereby in-
juring yourself and other people. Have
damaged tyres replaced immediately.
Tyre age
Have the tyres changed at least every
six years, irrespective of wear. This also
applies for the spare wheel.
Danger.
The sun's rays and environmental factors
cause tyres to age. The rubber from
which the tyre is made loses elasticity.
Tyres harden and become brittle, cracks
appear due to ageing. Tyres which are
more than six years old are no longer reli-
able.
Invisible tyre damage
Avoid crushing tyres against the kerb or
switching off the bus when a part of the
tyre tread is up on the kerb.
Danger.
Driving over the edge of the kerb or
sharp edged objects can cause damage
to the tyre substructure which is not
visible externally. Damage to the tyre
substructure only becomes noticeable
much later and could cause the tyre to
burst. This could result in you losing
control of your bus and causing an
accident, thereby injuring yourself and
other people.
Tyre load capacity, top speed of
tyres and types of tyres
Danger.
Exceeding the specified tyre load capa-
city or the approved maximum tyre speed
could lead to tyre damage or tyre failure.
This could result in you losing control of
your bus and causing an accident, thereby
injuring yourself and other people. For
this reason, only use the approved tyre
types and sizes for your bus model and
note the required tyre load capacity and
speed index for your bus. Pay particular
attention to country-specific tyre approval
regulations. These regulations may spe-
cify a particular type of tyre for your bus
or prohibit the use of particular tyre types
that may be approved in other countries.
In addition, it may be advisable to use a
specific type of tyre in certain regions or
areas of use. You can obtain information
on tyres from any EvoBus Service Partner.
Where twin tyres are fitted, the twin
tyres must have the same external dia-
meter, otherwise the tyre that has the
