Wheels, tires and complete assemblies

Every wheel below is made in our own factories — rubber mixed and cured in-house, rims stamped on our tooling, bearings pressed and assembled on site. Hub length and bearing ID are made to your spec at no tooling cost on most sizes.

2.50-4 through 6.50-8 Steel & plastic rims Ball, roller or bushing bearings Private label available
Pneumatic wheel 400-8RB
01 — Pneumatic wheels

Air tires built from our own rubber compound

We mix the compound, lay in our cording structure, then vulcanize and cure — so tread depth, sidewall stiffness and ply rating are ours to control rather than a supplier's. Tube and tubeless, knobby or rib tread.

Steel rims only on pneumatic wheels. Ball bearings available on every size; hub length and bearing ID made to order, rim colour to your powder-coat spec.

02 — Flat free PU wheels

Polyurethane fill, no punctures, no maintenance

Low-pressure polyurethane injected on our own line. The same rim tooling as our pneumatic range, so a customer can move an existing product from air to flat-free without redesigning the fork or axle.

Poly tray barrows

Injection-moulded tray on our steel frame and handle set.

05 — Custom OEM

If it is a steel part, we can quote it

Wheels are what we are known for, but roughly half our floor time is custom OEM work from a customer drawing or a sample part in a box.

Send a drawing or sample

Laser cut, bent, jig welded and coated as one operation.

Stamped parts

Progressive dies cut in our own tool room, kept on site for you.
