I've got a 2016 JKUR that came stock with KM2 tires, overall decent although I wanted to step up to 35s. Did so with 35x12.5x17 KO2s (E rated) on stock wheels running 1.5" wheel spacers. They were very quiet and smooth but I found them quite stiff (hit road imperfections hard even when aired down) and they seemed to push the Jeep around...bad tracking on uneven roads, etc. I feel most of it was to blame because of their size and less so because they were KO2s. I lost faith in them when I spun the back end out turning left at a stop light...it had been lightly raining and I was taking it easy. Had them aired down to 28 PSI. Could have been too aired down (bigger footprint, less PSI), too much tire for the Jeep, or not enough weight in the rear end. All combined it led me down a rabbit hole of tire research and I ended up with a combo that I'm much happier with. I stepped down to 33" tires (well 285-70/r17)...Lighter, easier for Jeep to control, less expensive, and they provide more clearance between tire and fender. Went with Cooper ATPs (Discount Tire's version of the Cooper AT3) and 17" x 9" Black Rhino wheels that have a perfect 4.5" backspacing (no need for wheel spacers).
After much research the ATPs were a winner. Many glowing reviews from owners citing excellent performance in any situation. They're known for great on road performance (grippy, quiet, great handling) and also have great off-road traction as well. They are a relatively inexpensive tire, and because you can get them through Discount Tire, you've got 30 days to try them out and see if you like them or return them no questions asked. Also for a minimal fee DT offers a fix or replace warranty and DTs are located almost everywhere. These are E rated tires with strong side walls however they hit imperfections softer than the E rated KO2s did. Finally, they come with a good 55,000 mile warranty to boot.
I've had these tires on pavement in rain, snow, and in nasty wet gravel roads and they are super grippy. My experience is they have much better wet pavement traction than my 35" KO2s. Again, I cite that largely to them being 33s (or technically narrower at 285) rather than 35s (more PSI). As a DD handling is awesome and confidence inspiring.
