The negative evaluation thus because I have to add my voice to the others Rezessoren which write that the parts do not fit together, fit to do it though (what is in the photo together), but it can be hardly a commercial wheelbarrow assign either to the holes in the Wheelbarrow be drilled larger, are too small or the ball bearing bushing from PU wheel has knocked out or removed and a completely different liner to be installed, and the distance of the hub must be reworked and there are models of wheelbarrows where the axis does not fit because they either too wide or too narrow (hence must spacers to buy extra)
the that wheel a little heavier than a tubular tire and the truck therefore not so easy drives like a cooling system is physically unfortunately so and so must live if you never want to have a flat tire - the bottom line is you can with 15 - expect an additional 25 if the wheel is designed to fit 100%
