It’s normal that the tyres of a pushchair show signs of wear when the stroller is used intensively, just as they would on a bicycle. This should not happen very soon though. But you can prevent this from happening. Make sure that all the tyres are inflated equally (1.5 Bar). For a comfortable ride the tyres should be inflated with equal and right pressure. Riding with tyres that are not inflated enough will cause premature and abnormal wear of the tyres. Additionally you will drive uncomfortably and strain your body too much.
Often a pushchair is being overloaded with a second child or heavy groceries. This exceeds the maximum weight of the pushchair and causes a quicker wear of the tyres.
It is possible to order new outer tyres for the Joolz pushchair.
