Trailer Jockey Wheel – up to 150 kg (250 x 85 mm, Ø48 mm)

This 150 kg jockey wheel is designed for smaller boats and trailers where extremely high capacity is not required, but maneuverability and ease of use are paramount. Its construction is sturdy steel with a hot-dip galvanized finish, ensuring corrosion protection for outdoor use and around water. With a load capacity of up to 150 kg, this support wheel is ideal for trailers carrying, for example, inflatable boats in the 3–5 m range, small fiberglass dinghies, smaller sailboats, or personal watercraft (jet skis).

The key advantage of this model is its 250x85 mm wheel with pneumatic tire. Compared to standard smaller wheels, the larger diameter and width of this tire allow it to roll over bumps and soft ground more easily. For instance, if you’re pulling your trailer across a grassy yard or a gravel path, the inflatable tire will absorb some of the bumps and won’t sink in as readily as a hard, narrow wheel might. This makes maneuvering considerably easier and requires less effort, especially when moving the trailer by hand without a vehicle.

The wheel assembly comes with a standard Ø48 mm shaft, meaning it can be attached to the trailer frame using a typical jockey wheel clamp (either one already installed on your trailer or purchased separately). The clamp’s screw mechanism (integrated on many models or as a separate unit) allows for height adjustment – you can lower or raise the trailer’s nose easily when loading your boat. The 150 kg capacity covers the needs of many small watercraft. If your boat is lightweight, this wheel will provide the stability and support you need without the excess weight or cost of a heavier-duty 360 kg jack.

Usage tips: Regularly check the pressure of the 250x85 mm inflatable tire – keeping the tire properly inflated (around ~30 PSI) ensures it can handle the rated load and perform optimally. If you plan to store the trailer for an extended period, you might raise the jockey wheel to take weight off the tire, preventing flat spots or deformation. When towing on the road, be sure to retract (swivel up) the wheel and lock it – this model typically features a manual swivel or height adjustment mechanism (depending on if an integrated swivel clamp is present). Otherwise, slide the wheel assembly to its highest position in the clamp and tighten it securely. With proper operation, the 150 kg jockey wheel greatly facilitates hitching and un-hitching your trailer and ensures you can safely maneuver your boat around on land.
