I would probably buy a Chinese tire before using a recap. But, back in the 196os when I owned a Corvette as a college student, I had some tires recapped as snow tires just to get around . These days, the Corvette spends the winter in the garage.
Green Diamond had silicon carbide chunks in the tread. (the shiney specs you see in the picture). Great for winter traction and doesn't damage the roads like real studsThere's a company in Tennessee which has abrasive tires in a few sizes.
The retread material has saw dust in it.
It's for orchard / farm vehicles where traction is needed without earth gouging
So yes. Have used Treadwright a couple times before with very good success for both offroad and snow grip and made in US. Would use them again. As for a passenger car, probably would pass.
