The Duratrac is a snow tire, I read somewhere the Canadian highway patrol SUV's are equipped with them. My daughter has them on her '90 4Runner (31/10.50x15) and they aren't very loud at freeway speeds at all. They're great in snow on her Toyota.
Had the TOYO A/T's on an '85 K-20 Chevy (285/75X16) and they were great everywhere.
