I threw on some 35" KO2's that I purchased. They fit very nicely on the Jeep, ride is smooth, very quiet tire. No noticeable difference in launch, torque, etc. No gear searching, RPM's are consistent with the stock 33's, however, the only issue I encountered was the spare would not fit without a spacer. My tailgate hinge has not arrived just yet so the shop I was at installed a spacer for clearance (pictured below). I am assuming this is due to a less aggressive offset on the stock wheels, but I could be wrong. I have seen others put 35's on the stock tire carrier and have very little clearance, but this is just my experience with these specific tires and the stock wheels.
