I got some urethane incoming to experiment a bit with casting my own wheels. I’m especially interested in larger wheels of around 100-120mm in size and all terrain wheels. The pneumatic ones are too large for my taste and the availability and prices of urethane AT wheels like the MBS ones is pretty bad.
I want the wheels to fit standard bearings and trucks. I will experiment with solid 75A castings and maybe 90A tubeless tire designs with hollow sections.
But I want some input from you guys. What would be your favorite dimensions? Is there anything you’d want in a (AT) wheel that the few commercially available ones don’t provide? What core placement would you prefer (centered, offset or side). Side placed cores would make mounting pulleys really easy but wear unevenly. Has anyone experience with those (how bad the wear issue really is)?
