Bought these tyres as a replacement for the factory fitted Continental Eco Contact 6, which were awfull in almost every way. I have to say the Goodyear Efficient Grip Performance 2 really improved the car, and as opposed to the Contis, they really feel like premium tyres. Dry handling is much more precise, better feedback, not so much understeer and faster steering response, and in the wet the difference is enormous, the car feels extremely safe. Braking in both dry and wet is a big improvement, they make you feel safe all the time, aquaplaning resistance much better. Comfort was ok with the Contis, but with the Goodyear, the ride became smoother and a bit quieter. Rolling resistance seems to be ok too, the fuel consumption seems to be the same as with the Conti Eco tyres.
They are everything I expected from this kind of touring tyres. Not exactly sporty, but really confortable and safe excellent for a family estate that we use for long journeys. I definitely reccomend them, well balanced tyres that don't seem to have any real weaknesses.
The only small fault I can find is the lack of rim protection in this size, maybe they come with rim protection on other sizes.
I hope wear is as good as the reviews say, I was dissapointed by the Contis, as the fronts were done after two seasons.
