Plastic centre pneumatics:

• Thick sections, large radii, multi-web design for strength
(stronger than most imported steel centres.)

• Corrosion resistant polypropylene for UV fade protection

• High engineering standrads for wobble-free wheels

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 (6 ply on HWY tread) for longer, rougher life
(many imports use 2 ply).

Tread patterns:

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.

IND: The normal industrial tread, a round profile with an even
pattern for general use.

RIB: Straight lines along the tread, common on wheelchairs
(plastic rims only).

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

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