This sounds ok for cars and other 3+ wheeled vehicles. But its unlikely for bike tires or other inline wheel applications as the outside surface of the tire is used for cornering. Unless the sides can be enclosed, it won't work.

Looks like police spike strips wont work anymore lol.

Screw that, no white walls? I cant be crusin the hood in my pinto with those things. Though they may be good for military apps.
