Trail cart wheels???

[ShesWhiskyInaTeacup]

Does anyone know where I might find some good heavy duty wheels for my Vanderveen (similar to a hyperbike) cart? The wheels are rather thick plastic, but as we get more into trail driving and gymkhana type stuff, I'm afraid of them cracking. Would an electric bike wheel work? The tires are 4" wide fat bike tires. I've reached out to HyperBike USA, no response, even reached out to Kbike USA, no response.

Any ideas?

You could try Kingston or Frontier? Maybe their motorcycle wheels would work.
