Had the tires installed 8/2012, Made a 1900 mile trip towing a 28' travel trailer 8,000lbs, with a ram 2500, with no problems. Tires felt great. The only time I got a sway was when passing a big truck at 75 mph, but that was my fault not the tires. Going to fast for what I was towing on SRW. So far 4,ooo miles and wearing great. I was leary of these tires from reading past reviews, but I'm glad I got them they handle great on my truck.
