I might roll it.....for the shear novelty

it's an exercise in engineering that will probably never see mass production .... and just so you know the sidewalls were not in place to show the technology and if they ever make out of the prototype phase they would have sidewalls

Without the sidewalls it looks like the Audi is running on bicycle wheels, which had a retrospective look to it. :p

A couple guys I know in the road construction business would disagree with you. There is a lot of interest from that industry in using these on heavy equipment. Traditional tires are extremely vulnerable to damage in a construction environment. In fact, if I recall correctly, that was what prompted this line of research from Michelin.

If I ever bought this product, the first thing I would do would be to remove the side wall.

and then you couldn't keep them balanced because of all the stuff that would get into tire

What balance-destroying materials would get into one of these that couldn't get stuck to the inside of a normal rim or jammed into the tread of a normal tire?

(I'm picturing a squirrel jammed in the spokes... )

Now crooks can run away from the cops' spike strips! :v

It is my expectation that engineers smart enough to arrive at this technology would be smart enough to utilize the static and dynamic forces to have the interior be self cleaning.

For example, if the interior were curved, instead of flat, as shown, then the centrifugal force would drive crud out. If the tread were perforated, then it would permit air and water to self-clean and decrease hydroplaning. If the center lattice were angled and shaped, it could cool the brakes and clean the inside.

Ifin they sold this technology with sidewalls the only benefit, perceived by the consumer, is no valve stem. Big deal.

Also, the Hunter GSP9700 road force balancing machine could be modified to add a cutting tool which could trim the spring spokes to attain 0 lbs of road force and tracking forces, better than any tire currently available.
