I had multiple sets of tires that I rotated between for a while before I decided to simplify a bit... E load has become my least favorite tire for road use, especially in wet traction I found to KO2 results to be dismal compared to a road tire.
For our trucks, I found the sweet spot to be a 3 ply to 6 ply tire depending on off-road use.
For daily driver / road use, I would not consider anything aside from a Michelin LTX M/S2 or similar. Its been the best on-road tire I have used and if you don't have a reason to get an AT, you are sure putting up with a lot of negatives for aesthetics.
Sure a nice road tire doesn't look like anything special, but the performance is spot on for what you need it to do on road. I don't shop for tires based on looks, I also don't shop for speakers because they match my room decor.
If you just must have an AT, then at least get an AT that is a bit more street-centric like the Cooper Discoverer AT3
It's just my opinion but the KO2 is perfect for the guy that SHOULD be running a mud terrain, but finds a MT to aggressive as a full time tire since it does drive on the street regularly. User is a an off-road focused weekend warrior who doesn't want to deal with owning 2 sets of tires.
