Designed for strength and performance, our wobble-free steel centred wheels boast 4 ply tyres, rims manufactured from 1.8 mm steel—with the 650 x 8 manufactured from 2 mm steel, and supplied with premium butyl rubber seamless (butt-joined) tubes.
The split rim design allows for effortless tube replacement without requiring specialised tools.
Supplied with tubes for high performance and improved weight carrying capacity. These wheels can be retrofitted with tubes if original tyres are punctured*. Steel centred wheels provide higher load capacity and reliable long-life performance. Sizes up to and including the 500x6 are manufactured from 1.8 mm steel, and the 650x8 is of 2 mm thick steel.
‘Deep Groove’ shielded bearings (indicated in order codes with SB) fitted to a toughened heavy duty housing enables true running and extra strength. Deep groove bearings can last up to 3 times longer than normal pressed bearings.
4 ply (6 ply on HWY tread) for longer, rougher life. Many imports use as little as 2 ply thickness.
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.
It is normal for air filled wheels to lose tyre pressure over time even if they are not being used and it’s important for your safety that you ensure that the wheels are pumped up to their recommended PSI before use—alternatively you can use our semi-pneumatic puncture proof wheels in applications that require wheels to never go flat.
For non-marking tyres, see our puncture proof wheels or plastic centred wheels.

Our code structure for pneumatics follows an internationally recognised convention that describes:
Tyre width (in inches) x rim diameter (in inches, measured from where the bead wire within the tyre sits on the rim).
So, for example a nominal wheel size of:
250x4 has a tyre width of approx 2.5 inches, on a 4 inch rim.
350x4 has a tyre width of approx 3.5 inches, on a 4 inch rim.
400x8 has a tyre width of approx 4.0 inches, on an 8 inch rim.
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 re-inflate. If you allow the tyre to go flat and you are unable to re-inflate it then you may need to buy an inner tube to be retro fitted to the wheel (available from our Spare parts for pneumatics and general wheels page).
Use of pneumatic wheels other than as recommended can be dangerous.
