Puncture-proof pneumatic wheels

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.
