Are these for real? Air Free Tires!(10 posts)

Are these for real? Air Free Tires!Live Steam
Oct 2, 2001 2:07 PM
I came across this while doing a search for some components. Can these be any good? has anyone ever seen them or used them? I know a few guys who could use them :-) They claim to have a life time warranty and have the same ride characteristics as pneumatic tires. This page has the specs for the tires

I would think they would weigh quite a bit more than tube type tires. Probably produce a much harsher ride also but I think that has always been the reason for not using solid tires.
What do pneumatic tires and tubes weigh?Live Steam

They post the weight of their 700x20 tire at 390g. They claim that the compostion of the material is 50% air. Would be nice to never have to change a flat on a ride again, wouldn't it?

the feedback I've seen suggests that there is a penalty in rolling resistance, weight and ride quality. However, I have no firsthand experience. They might be a good choice for commuting and bad weather riding where not have flats outweighs any performance penalty
Yes, they are for real, and crap besides!Kerry Irons

"They claim to . . . have the same ride characteristics as pneumatic tires." Yes, and I claim to be able to foretell your future by reading Taro cards. However, as this concept has been tried repeatedly every 5-10 years for the past 100 years and it has NEVER been successful, we can reasonably assume that this go is a total flop as well. The general knock is added weight and the most unresponsive, harsh, and leaden feel you could imagine. They do not flat, but since they never catch on in the market, we can safely conclude that this is a flawed concept.

Least we forget - pneumatic tires are what replaced the hard solid rubber tires on the original "bone shakers." Leave the solid tires to the tricycles, wheel chairs, and shopping carts. the compliance and ride quality is what has made pneumatic tires so succesful.

Also, funny how there is zero mention of the weight......

of them,but they state their wieght as 390g per for the "racing/touring" style tire. I also understand that they have been tried before, but the engineering of compounds has significantly changed in recent years. Maybe they would just be good for commuter tires. Who wnats to change a flat in a suit:-)
They weigh a tonne!Dutchy

I checked the page and a 700 x19c weighs 460 g, a 700 x 25c weighs 540g. There not as heavy as I thought they would be, but surely ride quality would be pretty average compared to pneumatics. Can someone out there buy some, then tell us all how bad they were :-)

He says they ride a lot harsher than pneumatic tires, but he bought suspension seatpost and says it's OK now. Of course, he rides about 15 mph. I wouldn't recommend them for the over 20 (mph) set.
buy em and youll go fasterishmael

when you take them off (after never having had a flat for the whole winter) youll go mach speeds and your bike will feel better than ever..ive never tried them but they sound great..then put them on again next year....dont be so skeptical folks, besides we arent always racing are we..ill buy them when i have the money and am out of tires
