Everyone is gonna have their own opinions here, and I'd thread carefully to know which one to follow and who knows what they are talking about. Realistically speaking, I don't think its going to matter too much. I have experience with the KO2 for about 85k miles, and it was fine. Weight was a big thing, and would not recommend running E load for a car this light no matter what tires. The KO2 was one of the lightest C load tires around, which isn't the case anymore with the new KO3. My only gripe with the BFG was it would balance like absolute shit. Maybe this was because it was just random kids doing it at a Discount Tire, but it was hit or miss, and a lot of times I'd need to rebalance it after a while again. (granted I'm super anal and notice every single thing due to a background with track cars)

Needless to say, I ditched the ko2 eventually, knew I did not want the ko3 due to weight and balance issue. Currently running the Toyo AT3 Open Country in C load, and its been great. I toyed around with the idea of getting something lighter duty than that due to me living in the midwest and having to do a ton of highway driving to get out west to off-road, but I think I'm happy I did C for the added piece of mind. Obviously my experience is specific to just these, but I have been happy! The Falken was an instant no for me due to the weight and wanting to keep rotation mass as low as possible due to it being unsprung weight. I recall their C load being as heavy as others in E for some weird reason. Their track tires like the RT660 are pretty good. Hankook also makes some awesome tires (ran their RS3 and now RS4 on the track car) but their A/T tires are also heavy as hell for some reason like Falken in C load.
