No. I can’t say what the smoothest is, but the OEM KO2 are much smoother than the Milestars. I have had both back to back.Milestar Pantagonias
It's not the added physical weight of the E tire that makes the ride harsher than with the C, it's the overall stiffer structure of the tire that doesn't offer enough give when rolling over imperfections. The E rated tire is meant for a vehicle that's capable of carrying more weight than our wranglers.The KO2 in 315/70/17 size comes with a C load rating, which is likely to be smoother than an E rated version. (I've not driven the E rated version, and only about 2 or 3 pounds separate them, so the ride actually may not be that different) I've got the C rated, and it rides beautifully, on and off road. It has handled everything I've thrown at it, from Moab to mud. I just did some off-roading with a Jeep club a few weeks ago and everyone had a wide variety of tires. There wasn't any situation where the KO2 appeared to struggle more than the others except thick mud. Even there, it got through, just not as easily as dedicated mud tires. However, there wasn't another AT that did any better.
I'm on a trip in Tennessee right now. We ran some moderate trails with some wet rocks and mud, then turned around and drove the Tail of the Dragon. There are tires everywhere that my do a specific job better, but I've never experienced one that does as well across the spectrum, and I don't know of one with a better ride or handling on-road, and they are quiet, too.
Btw, I've beaten the hell out of these for 24k miles with no side wall punctures or gouges. That includes lots of sharp rock trails. They've held up and haven't chunked or shown any issues with the tread. The wear has been excellent (5 tire rotation, so about 20k is on each tire) and they remain very quiet. I would not be surprised to see 60k to 70k out of this set, although I will certainly replace them well before they get to the wear bars. I won't let them get to where they become a set of skis off road.
