I think allot depends on speeds. Seems to me that bias ply tires wear faster at higher speeds (over 50 mph) as they heat up more. However, I can't recall where I read that, so it might be hooey. Also, braking and accel have much to do with how they last of coarse.
I put 25,000 miles on the 7.50-17 tires on the one ton I had. The tires were nearly new when I got them, but at the rate they were wearing, I suspect they'd have been worn out in another 15 thousand miles.
They did wear faster until they wore flat, as you describe Jomichael.
I should mention too, I have the lug type traction tires on the rear, and Hi-way ribs on the front, both were wearing at the same rate.
