Retreaded tyres
Retreaded tyres are not inspected for
EvoBus and are therefore not recommen-
ded. Existing damage is not always de-
tected during retreading. For this reas-

of the bus if retreaded tyres are used.
Cleaning the tyres
Danger.
Risk of accident. Clean tyres and suspen-
sion air bags very carefully. Round-spray
jets must not be used to clean the tyres
and suspension air bags. The water jet
may damage the tyres. Replace damaged
tyres.
Environmental protection
Damage to the environment: only clean
the bus at a washpoint intended for this
purpose. Heed environmental protection
measures.
