Airless Moutain Bike Tire

I found this really interesting. Why do the mountain bikes get all the good stuff, LOL.

Airless, puncture proof mountain bike tire

Wow, weirdest darn thing I've seen for an Mtb. The one in the pic is the one I have!

Although full suspension with spring loaded tires would be a weird ride.

What am I missing? How would you control the effect of air pressure on that setup. Kinda lost for words but if run something hard packed I want one t.p. and yet another on sandy loose soil...is it always changing and flexing?

Very cool, but I'm with Rola. I run different air pressure depending on the surface I'm riding on, but maybe that tire design will handle a wide range of conditions. None the less, I like it.

Isn't Hutchinson doing the same thing for road bikes and hybrids?

Interesting concept, but there are negatives and unknowns. I didn't see the rider doing any extreme riding, or doing drops. How do you adjust the tire like a normal tire which you can vary the psi for the given terrain. Also, with these concept tires being "open" as they are, I can see them getting clogged with mud and debris, making them much heavier as they get caked and filled with mud.

Here's a more sensible solution:

@cme FLAT FREE WHEELSETS OFFERS FREE
SHIPPING FOR MONTH OF NOVEMBER

Hurricane Sandy Highlights Need for No-Flat Tire Systems


FULLERTON, CA (CFEpr+) Nov. 2, 2012 - - @cme FlatFree Wheel Systems is making their pre-mounted wheel and tire sets available with no shipping costs for the month of November, in reaction to the cycling needs of Hurricane Sandy victims and people who want and need a bike that they can ride in any circumstances. The company was founded in July 2012 via initial funding through a KickStarter Campaign.

DISASTER PROOF
"Hurricane Sandy forced thousands of people to pull their bikes out of their hiding places so that they could get around,
" says Steve Boehmke, President of @cme Bike Parts. "Unfortunately, many of these bikes had flat tires from sitting around for months, and most people don't have adequate pumps and supplies to get their bike up and running in no time."

"The Serenity tires on the @cme Wheel Systems never flat and are always ready to ride," Boehmke says. "However, they only fit on a very specific rim size, and are more difficult to mount than standard tires, so we
are offering them as ready-to-ride wheelsets.

@cme's initial offerings include pre-built wheels with
tires mounted in 26 x 1.5" and 700c x 35, with 8/9
speed freewheels and flip-flop single speed hubs, and
Shimano coaster brake models. Higher-end hub
configurations are also available.

"I ride my @cme FlatFree equipped bike to get coffee every morning, but it will sure come in handy when the "Big One" hits Southern California!" continues Boehmke.


FOR ENTHUSIASTS TOO
Even though the wheels are attractive to casual cyclists,

Boehmke feels that enthusiasts will want a pair of these
wheels too. "Everybody I know in the bike industry has
a stable of bikes," continues Boehmke, "This is the

perfect wheelset to have on your town bike, fixie or
grocery getter. Get up, hop on, and get it done. Voila!"
@cme FlatFree Wheelset
DETAILS
The tires themselves are rated to last over 3000 miles,
and they weigh approximately 1400 grams a pair. "These
are not racing
wheels, for sure," Boehmke says, "But for
when your ride demands reliability, the @cme
wheel system can't be beat."

The tires also feature a reflective sidewall that illuminates
the bike for night riding. The wheelsets as currently
spec'd retail for @
299.
Contact Steve today to get a set of the ultimate bike
wheels for your urban bike or cruiser customer -
@cme FlatFree
Wheelsets.

I like Amerityre polyurethane tires. I'm running one on a mountain bike right now (front). (Turns out my rear rim is too fat for one.) I think it's great. It rides rough, like a fully aired up 1.95 BMX tread, but it corners hard, and it rolls fast. You need some tough rims for this. The tire does a lot to cover the rims, and can't pinch flat, but it does not do the same as the pneumatic tire in transfering impact energy all the way around the rim via the captured air. I think it would take some serious abuse to taco one, but you might have more spoke stress than usual. I ran this wheel on my full suspension bike before, and I hardly noticed it like I do on this bike. I've been using a pair on my kid trailer for a long time. The tire scuff from it being pulled by the left side of the frame, has given one of them some side tread wear, but they are still going strong.

Industry hack, the Hutchinson tire/wheel combos you posted are cool, but expensive! Basically, they are custom foam/urethane inserts in conventional tires. The Amerityres "snap" onto the rim, and can be mounted by hand, or if necessary with the little $5 plastic paddle. Totally user serviceable. I even took it off and put it back on another wheel. It's funny when people freak out that there's no valve stem.
