I have had both toyo outlasted the nitto by 10-15k. All I can go by is experience
I am not discounting your experience by any means, but tire wear is very subjective, however. There are too many variables that go into determining tire wear...unrealistic expectations, driving habits, terrain, maintenance, etc.
On my Dodge 2500 Cummins crew cab short box 4wd, I've got right at 50k on 285/75/17E Nitto Terra Grapplers with about 12k of that with moderately heavy towing. I'll probably get another 3-5k if I am gentle. Couldn't ask for better wear.
