Pneumatics: Nominal wheel size

Our code structure for pneumatics follows an internationally recognised convention that describes:

Tyre width (in inches) x rim diameter (in inches, measured from where the bead wire within the tyre sits on the rim).

So, for example a nominal wheel size of:

  • 250x4 has a tyre width of approx 2.5 inches, on a 4 inch rim.

  • 350x4 has a tyre width of approx 3.5 inches, on a 4 inch rim.

  • 400x8 has a tyre width of approx 4.0 inches, on an 8 inch rim.

Please note: These sizes are nominal only. For more precise dimensions, refer to the diameter x tread width listed alongside other specifications.

Maximum inflation of pneumatics

Warning: Do NOT inflate over recommended tyre inflation pressure (30 psi).

Do NOT allow tyre pressure to drop below 20 psi or wheel may deflate and become very difficult to re-inflate. If you allow the tyre to go flat and you are unable to re-inflate it then you may need to buy an inner tube to be retro fitted to the wheel (available from our Spare parts for pneumatics and general wheels page).

Use of pneumatic wheels other than as recommended can be dangerous.
