Plastic hubbed inflatable wheels on eBay

[FISH11]

Harbor Freight also carries a plastic hub model, I have seen then there before. I have a folding kayak cart that has those plastic hub wheels, but it sucks because they have no bearing and the plastic hub rides directly on the aluminum frame. The friction makes it harder to pull when you are pulling a fully loaded kayak with all the gear. I bought some of the steel wheels with bearing and built my own PVC cart that I take the wheels of and can store in the front hatch of my Malibu X Factor. If your Kayak doesn't have an inside storage to keep then dry then it would be a problem. I have seen the Wheeleez wheel on E Bay for $51 each if that makes it better. They still are the best when having to go over soft sand, everything else digs in and is super hard to pull through the sand.
