A couple of days ago, I received a pair of their Green Blizzard HD 26x1.75" airless tires (made in Great Britain, btw). They're made of an air-impregnated urethane compound, so technically they're quasi-pneumatic. The tread pattern on the tires I bought are made for dirt, with a flat ridge running down the middle that will do for the streets. I put them on my stump jumper (without a motor) and they feel like they are inflated to 45 psi. I can't tell much of a difference compared to pneumatic tires when I'm riding on them. The bicycle is only about, I'd say, a pound heavier with the two Airfree tires. I don't care; I'm not doing any Tour De France thing anyway. The other difference that I could detect is when I lift the bike and drop it: There is less bounce. It's like a dampened shock absorber....it will compress quickly and decompress slowly. It does absorb shock, but not as good as a pneumatic tire. In my humble opinion, it's better suited for use in full-suspension bicycles, as these types of bikes will help to absorb the more harsh vibration and shock that the airless tires cannot. I like 'em, because I often ride in the desert, and a flat tire is one less thing to worry about. And I don't like having to remove the rack mount for anything. The airless tires are expensive...with shipping & handling, they average about $47.50 per tire. I ordered a pair of street tires for my motorized bike and I'm still waiting. It takes them a long time to deliver.
