Solid foam tires are pretty useless. I would even prefer putting a tubular tire instead of a conventional inner tube inside a clincher over a solid foam tire (a little Winter training tip from Robert Millar ). If I was wanting to get from A to B I would still use conventional pneumatic tyres and I would still get from A to B much more quickly even if I had a half a dozen punctures, which is unlikely since I mostly use Specialized Armadillo Tyres and Slime inner tubes for general road and touring cycling.
