My boat trailer has a pneumatic jockey wheel - just that bit wider than a solid wheel to help when moving it around on sand etc. It takes a small, 3 x 4.00 innertube - but the valve stem had pulled away on mine so I needed a replacement. Happening to notice that the wheels on some of these mobility scooters that have spread like a rash of late (and I dare say there are some/many that are hardly 'needed' by their pilots) are the same size, I called into one of the multitude shops now selling the things. Yes, they could supply an innertube - for £9
I wonder how much they would have charged/ripped me off for fitting it
