Description
Overview:
This 48mm Serrated Jockey Wheel for Knott Avonride (MPN 800 0100) is a heavy-duty nose support for trailers requiring a robust 48mm serrated outer tube and a large-diameter solid wheel. It provides a 250kg static/dynamic load rating (about 551lb), suitable for frequent coupling, uncoupling and manoeuvring of loaded trailers. The wheel and tyre are the larger 230 x 65mm size (about 9.06in x 2.56in), offering improved rolling over rough ground compared with smaller formats. The serrated tube helps resist clamp slip during height adjustment. This variant is the higher-duty option within the Knott range, distinguished by the larger 230x65 wheel and the 250kg rating. Replacement service parts are available: the 230/65 wheel and tyre, and spindle 578005. No clamp details are supplied in the source data.
Key Features:
- 48mm serrated outer tube for positive grip in the clamp (approx. 1.89in)

- 230 x 65mm solid wheel and tyre (approx. 9.06in diameter x 2.56in wide)
