Exclamation Michelin Tweel

The future of radial tires - no air, last 3X longer than a radial, can be re-treaded; tire and wheel all one piece:

Wondering how the dynamics might work for a motorcycle application...

When I posted pics of these back in Dec '04, I told Cheryl about it and showed her the pics. She remembered, and when picking up her new M-B coupla months ago, she inquired to the dealership about those 'tweels'. Everybody there had the 'deer in the headlights' look ; butt thought they were neat. And one dude mentioned DOT approval concerns, while shakin' his head!!

Cheryl ended up with Pirelli tires, regular style; even tho I mentioned run-flat.

Betcha we do see 'em in the future tho - not sure 'bout bein' on two-wheelers; expecially with ABS and servo-assist systems. Pretty robust for them leetle spokey thangs to contend with, I'd think!!

From what I've read, the only thing keeping them off the market right now is that the current generation is extremely noisy at highway speeds. Like full studded snowtires on concrete slab. Once they eliminate the noise issue, I'll bet they will start showing up at the Big-O shop. Otherwise, they're very light-weight and shock-absorbant, able to deform much more than an air-filled torus.

I have no problem with getting used to new things and new designs...but even these are a bit too bleeding edge for me. In fact, I'd go as far to say they simply look STUPID. And...I heard they are EXTREMELY expensive.

I see a HUGE problem as they are currently pictured. That is the shape of the inside surface, being basically parallel to the tire tread. These surfaces would absolutely have to be tapered some from the center out to throw out mud/dirt/debris, otherwise it would be impossible to keep them balanced.

Otherwise, probably not a bad idea overall.

I don't want to achieve immortality through my work...I want to achieve it through not dying.

Why don't they put some flexi covering on the sides. That will reduce the noise
and also keep the dirt/grime out so they will stay balanced?

If they get 3 times the milage I'll bet they will cost 3 times as much...Kind of like the oil companies purchasing all the manufacturing rights to the caburators that incresed gas mileage by 300 percent...Just my thoughts.
