Semi-pneumatic Wheels

Puncture proof semi-pneumatic wheels

Semi-pneumatic wheels - puncture proof tyres:
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 steel centres. Manufactured from 1.8mm steel. [NOTE: some of the cheaper centres on the market are manufactured from steel as thin as 0.6mm]

Bearings:

Deep groove shielded bearings fitted to a toughened heavy duty housing enables true running and extra strength (Deep groove bearings can last up to three times longer than normal pressed bearings).

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 patterns available;

RIB: Straight lines along the tread, common on wheelchairs

LUG: General purpose, outside use.  Strongly marked cross lnes on a fairly flat tread surface.

LGG: Grey rubber LUG - non marking on floors

DMD: Diamond shaped pads on a flatter surface, often used in rougher construction sites.  Good for softer grassed surfaces but may become clogged with mud.

ZGG: Grey rubber zig zag - non marking on floors

KNO: This knobbly pattern is often preferred for outdoor use where a strongly marked tread takes a good grip on soft ground.

tyre is approved for a higher load or inflation pressure.

USE OF PNEUMATIC WHEELS other than as recommended can be DANGEROUS.
