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

Size outer tire: 12 x 1.75 x 2.25 Inch

The inner tubes have ‘american’ valves. Bring the pressure up with a bicycle pump, the advised pressure is 2.0 Bar (= 20 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.
