The compatibility of the tyres listed above depends
on the configuration and/or model of your wheelchair.
In case of a tyre puncture consult a suitable workshop
(e.g. bike repair shop, bicycle dealer ...) to have the
tube replaced by a skilled person.
The size of the tyre is mentioned on the sidewall of
the tyre. The change of appropriate tyres must be
carried out by a qualified technician.
CAUTION!
– The tyres pressure have to be equal in both
wheels to avoid a less driving comfort, to keep
the brakes efficiency and an easy propelling of
the wheelchair.
