900 is a good deal......if there is road hazard and free balance and rotates.
As Sockpuppet Esq has stated, the Hancook is a great tire for the money.
The Cooper AT's have not been as good for us.
The only Toyo's I have bought have been M-55's. What tire are you looking at? The Open Country?
Sumitomo is not familiar to me.......but I see a lot of "Falken" tires about. Mostly on feed pickups with lots of miles. Must be good tires.
