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 (NOTE: Deep groove bearings can last up to 3 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; other patterns can be offered by negotiation.

  • RIB: Straight lines along the tread, common on wheelchairs.
  • LUG: General purpose, outside use. Strongly marked cross lines on a fairly flat tread surface. Good for running in a straight line.
  • LGG: Grey rubber LUG – non-marking of 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 of floors
  • KNO: This knobbly pattern is often preferred for outdoor use, where its strongly marked tread takes a good grip on soft ground.

 

WARNING

The load and cold inflation pressures imposed on the combination of tyre and wheel must not exceed the recommendations, even though the tyre is approved for a higher load or inflation pressure.

USE OF PNEUMATIC WHEELS OTHER THAN AS RECOMMENDED CAN BE DANGEROUS.
