I have a 98 F150 4.6L, 4WD SCab w/107K miles. I tow a popup camper and an enclosed 2 place snowmobile trailer. Mostly highway use, but I do need rain/snow traction for the sled trailer. I have narrowed my tire choice to the Pirelli Scorpion A/T's or the Bridgestone Dueller Revos. I should mention that I am going with stock size 255/70/16's. The Bridgestone's look good but Tire Rack doesn't have any reviews on them. What are the thoughts on this. BTW - 55K miles out of each set of RT/s's. Too bad I had no reference and didn't know they were crap. I wondered why I spun on wet roads all the time.

 

I'm happy with my Duerler A/T revos so far, but only 1000 miles or so. Tire pics

 

I have had the Pirelli Scorpion AT and the Duerler AT (not revos) and the tire indicated below is much better. More tred depth better mud and snow traction and tuff as nails with a good highway ride with just a little hum, not like mudders I got 45,000 miles out of mine.

They are both great tires but the Dueller Revo has a much better treadlife rating.
