This is the second set of Assurance Comfortreds I have owned, the first being on an older Mazda 626 that I retired when I purchased this Sonata in 2006. On both cars, these tires seem to pick up some vibration from the 4-cylinder engine, and you definitely feel small imperfections in the road. Larger potholes are smoothed over effectively, so they would make great tires for city use. In the snow, they are nearly as good as winter tires, and I know a Dodge Charger owner near here that actually uses them as his winter treads.
Compared to the OEM Michelins on the Sonata, these handle better, especially on curvy back roads, but the Michelins are smoother on the highway. Will probably have the Comfortreds rebalanced after break-in as there is a slight vibration at highway speeds. Will report back then.
