I have bought over 40 of these tires for trailers, both single tandem and tandem duals. They are regroovable and can handle 4080lbs single, so they are one tough tire. They are a little smaller in diameter than most 235/85/16 tires which I like because the trailer sits just a little lower and makes loading that much easier. I haven't found a tougher tire than these for heavy duty work, great speed rating of 75 mph, and they cost less than most of the junk 235/80/16 tires.
