Well I'd have to say the Goodyear wrangler duratrac Is the best, I've had nitro mud terrains, they are worse than stock tires on the ice. They were reigned for mud and are a very hard rubber, but gOod in deep snow. The duratrac is a great blend of a streetable highway tire. And it's passed goodyears test and is an official snow and ice tire by there standards. Also the tire comes pre drilled for studs!
This will be the only tire I ever get until they stop making it, plus it looks cool lol
