it's an interesting concept. has anyone had experience with these or what are your opinions? I am still going to stick with some bfg's, but stumbled upon these.

Wierd! The description of how new diamonds appear on the surface is exactly how my shop teacher described how a grinding wheel works. Wonder if they actually work?

I'm not a fan of retreads or even "remolds" but I've been told by a guy who drives a wrecker that this type of tire (with the diamond-tech granules) is pretty good. I just don't trust it myself, the idea is good, but in practice, I dunno.

You know walnut shells used to work pretty good too....this is not a new idea
