I had these tires installed some 3 years ago and absolutely love them. They have excellent wet and snow traction. Not sure about mud but they have done well in what little offroading I have done. They are quiet on the highway and are wearing as expected. Will get another set this summer for my Taco when I have to replace those.

 

You may want to say whether this is the regular duelers of the revos.

 

I have a set of the Revo's, great tires! They work really good in the mud for A/T's.

 

These are just the regular at's, not the revos

 

I bought the 31x10.5R15 because I read so many positive reviews on tire rack. They were even rated higher than the BFG's. I'm really glad I bought these, they're great tires. I've used them on road, in the wet, and off road. Never hydroplaned, or slipped on the road. They have good tread wear and low noise. Offroad they grip till no end, even in sloppy mud they clear pretty well when you turn them quick. Not like my TSLs, but great for an A/T tire. Overall, I like the Revos better than the set of regular Dueller A/Ts Ive had, and I've outperformed similar 4runners offroad equipped w/ BFG A/Ts w/ the Duellers on my runner. Great tires.
