I suspect there is a sidewall, or will be, for any production "Tweel" designed for cars. Most likely these will gain favor for military and industrial vehicles before they will for cars though. The main disadvantage is they won't be dismountable, so you can't change wheels. For the majority that might be okay, but many like to change wheels. If there is a sidewall that makes them look more like a normal tire (and I'm sure there is, photo was probably for journalists to show inner workings -- wouldn't be preactical to leave it open) it may be a good option though. Would be great for four wheeling if in the right sizes and tread paterns -- never a blow-out!

Hmm... how about making it say 40" tall, put an open body on top. If they ride so well, a plain bent piece of spring steel from the local blacksmith ought to do 'tween 'em. And a hay-powered quaduped in front? Lets see you resist regulating those emissions! Man I truly hate the trend towards 0-profile tires. And they've got to ride just awful on older cars. -- Frank Swygert Publisher, "American Independent Magazine" (AIM) For all AMC enthusiasts http://farna.home.att.net/AIM.html (free download available!)
