I played with the idea using steel springs in wagon wheels for a Ring of Fire series fanfic (I highly recommend the books if you like time travel stories) but I am not convinced that loopwheels are a better solution than a springy seat post.

With any wheels there is always a little trepidation about hitting larger more inanimate objects but with Sam goading me on I started to aim for rocks, ruts and tree roots (did I mention we were riding off road!!!) and in every instance the wheels soaked up the impact, leaving me free to ride the bike without worry of knackered rims, aching arms or even getting up out of the saddle to soak up the impact – you can just let the wheels do the work.

'We're at preproduction - we've made wheels, but we're now hoping to get funding for tooling so we can mass product them, and we are planning to spend the next two months getting production ready.'
Making a bunch of assumptions about usage, you're up for a set of six of these huge hoops a year plus a spare, giving you a 10-year tire budget of around $2.66 million per truck. (These figures are adapted from the ASW company's own comparison spreadsheets, which use rubber tire pricing of $110,000 each from 2009. These tires are now much cheaper according to our research.)
