To inflate the rear wheel tyres on the Joolz Day, it is important that you use a standard bicycle hand pump or floor pump (non-electric). To pump it up, remove the valve caps first, then inflate the tyre (like you would do with a bicycle tyre). Note: the maximum pressure of the tyre is 28 PSI.
Make sure that all the tyres are inflated equally (28 P.S.I). Like tyres of a car, the tyres should always be at the right pressure to ride comfortably. Correct pressure prevents tyres to wear and decreases the risk of getting a flat tyre.
Please do NOT inflate your Joolz rear tyres at the service station as you could risk serious injury due to over-inflation.
Furthermore, when flying reduce the air pressure in the wheels to avoid punctures which can occur to the pressure in an aeroplane.
