As an All Season, the DTs are a great tire, comparable to many others like the KOs. But compared to a "Winter Tire" DTs are a summer tire. Winter, Snow grip is all about multiple small snipes which pack with snow and stick to snow on the ground like a snowball. And throw that snow to pack with fresh snow every revolution. The last thing a winter tire should do is spin, traction is all about snow sticking to snow.
