I put Kelly Safari TSR's on a 3/4 ton GMC I had. I also had them studded. The most I hauled with them was a horse trailer since I only had them on in the winter. Great tire IMHO. I have a RAM 1 ton diesel now and tried Duratracs on it last winter. I didn't like how they handled in deep snow so I took them off and put some Kelly TSR's on it They were also wearing out pretty quick. I think the TSR's are a better tire. Of course it maybe the heavy diesel that makes me not like the Duratracs. I don't know. I'll have to see this winter how the TSR's work on it. I did put the Duratracs on my 3/4 plow truck that came off the RAM. Maybe they'll do better on it.
A friend really likes the Cooper M+S, especially since he got them studded.
