Anyone chiming in w/ less than a 3/4 ton w/ E-rated (load) tires does not use the same type rubber as OP. I love duellys but maintenance costs go to a whole 'nother level w/ regards to tires and especially brakes.

I bought the Toyos in E-load for my last Superduty and absolutely hated them. They had the worst *tread squirm* on the highway that I've ever felt and it never went away. The only reason that I did not return them immediately was because the tire dealer convinced me that it was only a temporary thing while they were new and I bought them in MN. and proceeded to drive home to CA. right away. Maybe a great tire in other ways, (toughness/wear/etc.), but absolute garbage to drive on. My old, balding worn-out tires drove 10x better on the highway.

Go on a heavy-duty truck board and ask around, you'll get a lot more relevant experience than here. TIrerack.com's reviews can be helpful but you need to read several to get any kind of quorum.
