Plastic-centered pneumatic wheels

Australian-made and UV protected

Our plastic-centred wheels are designed with thicker UV protected polypropylene sections in a multi-web design, making them stronger than most imported steel centres.

Combined with our standard 4 ply tyres and premium butt-joined tubes, these wheels offer excellent performance in wet and corrosive environments.

Plastic-centred pneumatics are supplied with butyl rubber seamless (butt-joined) tubes as standard. These premium tubes provide greater reliability and longer life than cheaper alternatives. Tubes can be replaced if originals are punctured*. Plastic-centred wheels are the low cost alternative, with excellent performance in wet and corrosive environments.

Plastic-centred pneumatics with butyl rubber seamless tubes

Thick sections, large radii, multi-web design for strength (stronger than most imported steel centres).
Corrosion resistant polypropylene with UV fade protection.
High engineering standards for wobble-free wheels.
High quality butyl rubber seamless (butt-joined) tubes.

Bearings for pneumatic wheels

Heavy duty 'deep groove' shielded bearings (indicated in order codes with PWB) fitted to a toughened heavy duty housing enables true running and extra strength, or plain bearings (PWA). Deep groove bearings can last up to 3 times longer than normal pressed bearings. Precision bearings (indicated in order codes with a PQ) provide ultra-tight tolerances. Roller bearings (indicated with an PR) are available in 200 x 50.

Pneumatic tyres

Four ply (4 ply) for longer, rougher life. Many imports use 2 ply.

For wheels pulled or pushed at low speeds (not driven) the tread pattern is not critical. The following are standard. Other patterns can be offered by negotiation.

It is normal for air filled wheels to lose tyre pressure over time even if they are not being used and it’s important for your safety that you ensure that the wheels are pumped up to their recommended PSI before use—alternatively you can use our semi-pneumatic puncture proof wheels in applications that require wheels to never go flat.

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.
