I'm not sure how helpful I can be with that one. I would say that they are smoother than the OEM tires. Kind of softer? The buckles/potholes don't hit as hard as they used to (none of the streets near me have smooth roads). I've never had any tire that has "comfort balance technology" or anything comparable to it, but I would say there is a noticeable difference. I do have a little bit of a shimmy around 60-65 mph sometimes, but I'm attributing that to the botched alignment I got from a independent shop in the area. The rig drove straight when it went in, but I've had it there twice, and it still pulls to the right. I'm getting it realigned by my normal toyota shop tomorrow.
