Yeah, I considered the opposite of what I ended up doing, as well, which would have been Nittos for the truck, and KO2s for the Jeep. Ultimately I decided to split them and see if I preferred one over the other. The truck and the Jeep aren't perfect analogs for one another, of course, but I'm still trying to run a bit of a test.
So far I'm really pleased with both. They're both very quiet and smooth, good grip in both dry and rain. The Nittos look a little more aggressive and I really like that on the Jeep Wrangler, which has 17" wheels and I went to 35s on it, from the Rubicon stock 33s. So you get a lot of sidewall, a lot of rubber, and it looks great.
Since the F150 is on 20" wheels, and there's a lot less sidewall, the contrast between the aggressive look of the Nitto and the slightly less agressive K02, isn't really all that noticeable. So I was okay with the BFG for this go-round. We'll see how they perform over time.
