Fixed my rear alignment problem (see other thread), now the car handles 10000x better. With that said, these tires are still a slight decline from the OE tires in terms of handling, though traction seems pretty similar.
Fuel economy is very good, computer indicated average is slightly over 50 mpg after 5100+ miles. 50-52 mpg calculated tanks are now becoming quite common, which was unheard of with both the original tires and the Primacy MXV4.
Some of the harsh ride has gone away after a rebalance today. All of the tires were about 2 ounces off. I attribute this to the lube used doing install, as the tires must have slipped on the rim during the first several miles. I have experienced this with other tires as well so it is probably not exclusive to these tires - which makes it more important for anyone to consider having their tires rebalanced at the first rotation.
