Two interesting new tire ideas from Michelin. No more flats or checking tire pressure. Also, smooth ride but good cornering is possible.
If it arrives, will the tread patterns be interchangeable from design to design, or will each Tweel be proprietary so you have to have a Goodyear Tweel to install a Goodyear tread, and a Michelin Tweel to install a Michelin tread? My guess is no, it would be similar to what we have now where you buy a wheel and put the appropriate size tire on it.
