My test platform for tires was a ‘13 F150 crew cab 4x4, so similar size and weight to Ram 1500. I went through 4 sets of tires over 200,000 miles here in Colorado. Some stock crap, Duratrac 275/65/18 E load range, Michelin LTX M/S 275/65/18 load range SL, Duratrac 275/65/18 E.
Comparing the Duratrac to the Michelin, the Michelin was quieter and rode smoother, probably due to load range SL. The duratrac got better traction everywhere, wore excellent, but needed rotated regularly (I do every 10K miles). They are not whisper quiet, but the sound deadening in modern trucks makes that a mute point.
As was stated earlier, look at the load rating of the tires you plan to buy. I’ve heard too many bad stories about the SL and C load range Duratracs. But they have different build quality. The load range E tires are solid. As an example, I was on the highway in Denver when my low tire pressure warning light came on. But I was late for a meeting in Cheyenne Wy (2 hours away), so I checked pressure (28 PSI) and rolled on. I made it to Cheyenne, went to my meeting, then headed to Discount tire. The tire pressure when I got there was about 20psi. They pulled the shank of a full size screwdriver out of the tread of my tire, which had been flopping around in there for 150 miles, and I only lost 25psi of pressure. Repaired the tire and I ran another 25K miles without issue. The E range Duratracs are solid tires.
