Buying a new tube - Understanding wheelbarrow, scooters and mowers tire and tube sizes...

Unlike car and truck tire sizes which are fully standardized, wheelbarrow tires and tube sizes are so confusing since some indicate inches, some millimeters, some use the slash "/" symbol combined with a dash "-" and others the multiplication sign "x", if not a combination of two or all of these symbols!!
​The only way to avoid confusion is to identify the rim size, then deduce the tube diameter for buying the right replacement.
Please note that the tube size marking might sometimes refer to the tire size or sizes to which it is suitable since one size of tube can fit into several but similar tire sizes.
Our below wheelbarrow / mower / scooter tire - tube size examples will help you identify them:

As a result of the above examples, it is therefore understood that for wheelbarrow, mower and scooter tires and tubes sizes:
  • The number before the slash refers to the tube diameter in inches
  • The number after the dash refers to the rim diameter in inches
  • The number before the multiplication refers to the outer tire diameter in inches
  • The number after the multiplication refers to the tire width in inches
  • Numbers that are too big to be inches refer to the rim size in millimeters
