I generally get over 40k out of them on my 9k+ heavy srw work truck. Previously it was a struggle to get to 40k with higher priced tired. With all the sipes on them they do very well in the rain, excellent in the snow/mud. Pretty quiet too. Not michelin quiet, but comfortable to use in a gasser.
They wear pretty nicely on my dually, but it will take a while to get that many miles on the dually, it sits in the comfy garage these days unless I need to haul coal or something else heavy. For the first ~10k miles on the dually they have wore very nicely though. I only rotate the outer 4.
