If the (inner) tube of the Mobinova Outdoor rollator is worn out or damaged, replace it easily.

Size tube: 12 x 2.125 Inch, 45 degrees USA valve

This inner tube has an ‘american’ valve. Bring the pressure up with a bicycle pump, the advised pressure is 1,5 Bar (= 15 PSI). Be careful if you do this at a car service station: the standard pressure is often too high (2.2 - 2,5 Bar). At a bicycle repair shop they can also do it for you.

This tube can also be used on 12.5 Inch wheels
