I have the silent armor in load range e on my ram 1500, they came on it stock. I had noticeable difference in treadwear from front to back at 4k miles when I rotated them. Per door sticker I should run them at 43psi. I usually run them around that in the winter but with towing the tt every weekend I leave them between 65-70. I do not think they will last more than 30k miles however they do have a 50k warranty but for what they cost I think I'm going to look at other options. My fil has the duratracks on his 12 f350. They seem decent but do hum at all speeds. Can easily be drowned out by radio but it is present. Mine do not hum. Another thing to consider is the extra tread depth of the duratrack, however they could have a softer tread ccompound and not last as long.
Personally I'm not overly impressed with the silent armor traction in wet snow. I think its in part of the tread being close to one another in the middle of the tire. For this reason along with the price I think I'm going to get a set of coopers that have the aggressive tread design bc I can get those tires for about 65$ less a tire on discounttiredirect.com
