Airless "Tweel" tires
Airless "Tweel" tires
(OP)
I did a search and didn't find anything posted in this forum since 2005. Is anyone aware of the latest developments / progress on this technology?

RE: Airless "Tweel" tires

Polyurethane has been used to make faux spokes over steel wheels, but structurally, I'd worry about it in two situations: Driving anywhere in the US' southern half in summer, where pavement temperatures can get high, and driving in any mountainous region, where brake temperatures can get high.
The low end of the temperature range might be a problem, too. Even if the material doesn't fracture at low temperatures, its effective spring rate has to be different than at high temperatures, so NVH issues might be a problem.

Word of Caution: Michelin was also responsible for the TRX and PAX. Both of those bit the dust and left a lot of folks with wheels for which the tires were not only difficult to obtain, but also expensive!
