Has anyone seen this? Could you imagine retorfitting our cars with this new technology?

I wonder what happens if they get full of snow, ice or even just dirt?

No doubt, a large chunk of mud or ice could really throw your tire out of balance. I wonder if centripetal force would throw it off. If it were ice, could the heat from brakes melt'em off? Looks like frontier wagon technology came back to haunt us. Almost like bell bottoms, Hmmm. . . .

Here's a little more info!

I wonder how those wheels would deal with high ammounts of torque...

I bet they would look like the sidewalls of a dragster taking off!
