Airfree bicycle tires

Airfree tires of polyurethane microfoam
cannot go flat or blow out. I have them on
five bikes since 2001.

Felix Wong commented,
"Conclusion: I am impressed by these tires. They have convinced me that all generic claims made about modern airless tires — heavy, poor rolling resistance, hard to mount, crackpot money-making schemes, etc. — are bunk.

That they ride harsher than pneumatic tires may be true, but only marginally so. I personally don’t think they ride all that uncomfortably (and note that when I did my commuting rides, I was wearing jeans instead of padded cycling shorts!), and I especially like how I no longer have to worry about flat tires, carrying tire changing tools, or pumping up the tires before going into town.

They are perfect for the Ultimate Commuter Bike, and I believe they may even viable for training rides for competitive cyclists who don’t want to deal with flats. The main people they would not be suitable for are racers and people who are really picky about ride quality (most of these people ride sew-ups anyhow :) ).

If you try them out, please let me know what you think.
