Puncture-proof pneumatic wheels
Premium long-life tyres
Our premium polyurethane foam-filled tyres provide the greatest performance and reliability. The foam filling provides a light-weight bouncy performance, similar to air-filling, but without the risk of flat tyres.
These wheels boast 4 ply long life tyres, fitted to two piece wobble-free steel centres that are manufactured from thick 1.8 mm steel, unlike cheaper imports with 2 ply tyres and rims made from thin 0.6 mm steel.
Polyurethane foam-filled tyres are the premium ‘pneumatic’ (or semi-pneumatic) wheel option. The wheels are puncture proof and provide the greatest performance and reliability. Semi-pneumatics are fitted to two piece wobble-free centres, manufactured from 1.8 mm steel.
Puncture proof tyres
Polyurethane foam-filled tyres are premium pneumatic (or semi-pneumatic) puncture proof wheels that provide the greatest performance and reliability. The foam filling provides a light-weight bouncy performance, similar to air-filling, but without the risk of flat tyres. Semi-pneumatics are fitted to two piece wobble-free steel centres. Manufactured from 1.8 mm steel. Some of the cheaper centres on the market are manufactured from steel as thin as 0.6 mm.
Bearings for pneumatics
‘Deep Groove’ shielded bearings (indicated in order codes with SB) fitted to a toughened heavy duty housing enables true running and extra strength. Deep groove bearings can last up to 3 times longer than normal pressed bearings. Precision bearings (indicated in order codes with SQ) provide ultra-tight tolerances.
Tyres
'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.
Maximum load capacity
Each wheel can carry the recommended load capacity at walking pace—8 km/h. If you are intending to tow your load, it is recommended that you do not exceed 15 km/h, while carrying half the recommended load capacity.

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.
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.
