sounds like a blancer problem. i ran two set of AT3's and got 67,000 and 64,000 miles per set on my diesel. Great tire,always blanced, smooth rolling. only reason i went with the STT's was for a more aggressive tire.
I drive 28 mi round trip every day to/from work in my Lexus GX470. If I was looking for a dedicated offroad tire, the AT3's would have been near the bottom of the list. Rather, I wanted something good for commuting, good on the beach (OBX), and could do light/medium offroad work.
Re Escalade tires, probably look to their Xeon line or whatever it's called - not the Discoverer line.
