I have some Toyo Open Countrys around. But my all time favorite LT tire is the load range E Toyo M-55. From 235-75-15 for the Toyota 4X4 and baby Blazer to 255-85-16 on the 3/4 ton 4X4. I typically get 60K from each set.
They need to be rotated every ten K as the front lugs will start cupping. But that is typical of traction tires in the steering position.
