You can look back at some of my posts. I can get 22 mpg with my heavy 295 10 PR Toyo RT Trails in the right conditions. Mileage has very little to do with tires, but a lot more to do with driving conditions and driving habits.It’s not that I’m looking to increase my mileage just not looking to throw something on so heavy that it tanks further lol.
I like a decent looking aggressive tire.
I've found the ZR2 to perform the best when I'm getting 5 mpg creeping around the desert trails or pulling 10 mpg hammer down smoking "fast" cars driven by slow drivers. But I did 3000 mile round trip last fall and it did great cruising on the highway 65-85 mph.
This is what the Toyo RTs look like new and after 12k just took this picture a few minutes ago. You can see that there is maybe 1 mm of wear on the lug surface and maybe 2 mm on the edges of the lugs. Two rotations at 5k and 10k.
They are only $400 each, so the least expensive tires you can buy. Why you haven't already ordered them is beyond me.
