quired to obey the public trafc regulations.
the tyres are inflated to the correct tyre pressure.
Whenever possible, avoid parking the wheelchair out-
doors and on direct sunlight (UV light) as it causes the
tyres to age prematurely. As a result, the tread surface
hardens and corner pieces break out of the tread.
Otto Bock recommends to replace the tyres every 2 years
regardless of wear and tear.
When the wheelchair is not used for extended periods of
time, or if the tyres are heated strongly (e. g. near radia-
tors or by sunlight shining through a window), permanent
deformation of the tyres will result. Therefore always make
sure that the wheelchair has sufficient distance from
sources of heat, move your wheelchair from time to time,
or jack up the wheelchair when storing it.
