Wow Jeff, I can't believe you have had such great luck with the AWR's. I had a set of the old sytle AWR's and my father had a set as well. Neither lasted more than 40k and that was on a 1500 Chevy gassers.
On our work trucks we have had 3 sets of AWR's (had all new tires put on all three trucks at the same time). We do alot of driving on dirt, taller grass, mud (wet dirt), and snow. The tires were great for the first 5000 miles, but after that not one set was worth a $%^&. They were junk in the mud, which was to be expected because of their tight lug pattern, but they were even junk in the snow. I don't just mean snow in the field. All snow, light, heavy, on the road, or in the field. These things don't even have traction on wet grass. Not one set lasted over 30k on the work trucks.
Glad to hear you experience was better than ours.
