I just installed these tires about 300 miles ago, i have already noticed a 9% increase in MPG. These tires are extremely quite, but are a lot floatier than my previous summer tires. My wife even noticed how much softer they were, and she is no car person at all. This being said they feel great, and seem to have almost the same amount of grip of my previous summer tires. I have yet to try them in the rain or snow, but im very excited to try them after all the positive reviews on them. The road noise is very minimal, and they absorb road defects really well. They feel a lot better then the OEM continentals that came on the car.
