I'd have to disagree about the ko2s, I'm running 37s ko2s, on snow and they are very very very good. Muds plain suck on snow , not enough sipping in the tires.35’s to 37’s is a very small change. The final drive ratio will be almost equal to a stock rubicon with 4.10’s and 33’s. Approximately 1950rpm at 70 mph. As far as handling, assuming the same tire is used, will be a negligible difference. Even off road the difference isn’t huge, unless you are going with a more aggressive tire. If you are stepping up from the KO2 to a hybrid tire or full mud terrain then the off road difference will be huge. We road trip our JLUR all over on a 37” extreme terrain, and my wife daily drives it, but it’s not for everyone. They are a little louder on the street, wet traction suffers a little, I hear traction in ice is really bad (not an issue in CA) but in the mud, deep snow, soft sand, loose dirt, etc any mt will be vastly superior to the KO2.
