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:

'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
  • IND: The normal industrial tread, a round profile with an even pattern for general use.
  • 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.
  • KNO: This knobbly pattern is often preferred for outdoor use, where its strongly marked tread takes a good grip on soft ground.
  • ZGG: Grey rubber zig zag - non-marking of floors

Tubes

Tubes are high quality butyl rubber seamless (butt-joined) for premium ride quality, high load capacity and long life.

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 reinflate.If you allow the tyre to go flat and you are

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

* ID of bearing is reduced by inserting flanged nylon bush into the standard bearing - add 4mm to hub width
