We need to buy the rubber tire for the smaller wheel and we live in Norway. Are there any stores that have these stroller hear? Or do we have to buy it from Poland?
As I am not from Norway and not sure where you are in there (it is not a small country), I cannot say if you really can buy [[article:motsukechita|spare parts (more about those HERE) there, but I would definitely recommend visiting a better bike shop as they keep these or can order these quite often. Apart from that, find a distributor of the brand your stroller is, or yes, contact Poland / the manufacturer.
