I've run the hankook and the cooper AT3. Cooper wears longer and is better in the snow. I have some Toyo AT's I'm trying to run out in the summer that are junk, only bought them because they ther first 4080lb rated E's on the market.. This year I switched to cooper studded M&S in the winter and will be running cooper AT3's in the summer once I burn the last bit of tread off the toyo's. On my wifes truck we have been running copper at3's as a summer tire, and they have been great.
