Green Diamond tires

Anybody ever heard of this tire:http://www.greendiamondna.com/concept.html
The idea sounds neat especially for winter use. They imbed carbide granules throughout the rubber. The Ultra Track has a mean looking tread design but the company says it has good highway handling as well. it is an Icelanic tire. They should know something about winter tires. thoughts, anyone?

Some states don't allow studded tires because they wear away the road surface. I wonder if these slip through a loop-hole in the law, and for how long.
Neat idea for winter, though. If I were back in Minnesota, I'd have to consider it.

Supposedly they are not studs, do not damage the roads and can be run year round.

Green Diamond tires

Well, I do live in Minnesota -- the state where absolutely nothing is allowed, included studded tires.

All of the info I could find on the web was favorable, but it came mostly from Green Diamond's inventor (extolling the virtues of the tire itself) and from tire retreaders and their trade groups (glad to have a new source of business).

They are retreads. Not only will the castings come from various manufacturers, but they will be turned into Green Diamond Tires by any number of firms that have purchased the rights to the technology.

The only similar tire I've heard of is the Blizzak, which has traction-enhancing granules embedded only in the outer part of the tread. Once they wear down, you're left with a normal, high quality, all-season tired, or so they claimed, which was why Blizzaks never appealed to me -- I saw myself trying to figure out how to utilize three sets of tires: really-great-winter tires, half-worn-out-still-really-good-winter tires, and summer tires. (A more recent reason is that they are made by Firestone).

Green Diamond Tires have the granules embedded throughout the tread and shouldn't have that problem. Their performance on snow and ice is claimed to be significantly better than Blizzack's. Keep in mind that that all info is from/through their own web sites.

Besides the website in the mentioned in the base note (http://www.greendiamondna.com/), there is also http://www.greendiamonddirect.com/, and the Icelandic company is at http://www.newind.is/.

I find these intriguing but I'm not inclined to go driving down the highway on retreads at 75 m.p.h. with up to 8800# of truck plus an occasional trailer, nor am I inclined to slow down .... (Think Firestones & tread separation!) Personally, I will wait until there are plenty of other Super Duty owners who have tried them and are still alive to say how great they are.
