This wheel made of puncture-proof polyurethane foam features an offset hub for easy installation on a cart axle. The advantage of this material is that it will last at least 3 times longer than an inflated version while allowing for smooth movement. Rolling over nails is no longer a problem!
The ball bearing also helps reduce effort during movement.
Be careful if your axle is rusty; it will be necessary to sand it to clean it.
If you want to switch from an inflated wheel to this puncture-proof wheel and you want to check that the model is exactly the same, your old punctured wheel should be marked: 4.10/3.50-4 regarding the dimensions.
