Suitable for 10" (250mm) jockey wheel This Jockey Wheel Buddy has been designed specifically for the Surf Boats of Surf Life Saving Clubs of Victoria . It is also perfect for off-road caravans, camper vans and trailers, horse floats, food and coffee vans, boat, car or tradie trailers and farm/machinery workshop trailers running big inflatable or solid 10" jockey wheels. JWB All-Rounder 250 with Solid Base has added strength to keeps the jockey wheel above ground and stop all subsidence in soft, sandy or even muddy ground. The solid base also prevents breaking and cracking under load as the wheel is off the ground, and provides a jockey wheel stand even if the inflated wheel is flat. Once fitted, it will pivot easily around the jockey wheel for easy stowage when travelling. No more carrying muddy brick pavers or blocks of wood. The JWB All-Rounder 250 with Solid Base is another fit and forget product.
