I looked at the KO2 and people claimed a mileage drop of about 2 mpg. Again, that is what I read searching the tires. I picked one up at Sams club and they were really heavy. I assume that leads to durability, and these were rated very highly by tire rack. I don't know anything about the Toyo. I opted for Michelin C plies for mileage, ride, lifetime, and noise. If I did not care about mileage, I would have bought the KO2s. I don't think my secondary roads and trails that I hunt need all the KO2s have to offer.
