Tires were bought and put on my wife's car but I drive most of the time. These tires are so much more comfortable than the factory tires (Kumho). The ride is quite and so smooth it seems like we bought a new car. They were a little more expensive than tires we could have purchased but we felt confident they would provide us with everything we were looking for in a tire (I.e., safe, smooth, quite, vehicle response). There have been no problems with balancing the tires and they still ride just like they did the day they were installed. This is our second set of these tires (the other set was on a KIA Sedans van) and we are very pleased with them.
