I drive them on my Golf MK5 only during summer time. 2.5 years old now.
Drove them for 27.000km and they are down from 8mm to 5.7mm tread. I do rotate them front and back regularly.
Cons:
-the only big downside is the road noise, which isn't on the table here and I can't score it in this review. The tyres are a bit noisy, especially on rough surface, you can hear them quite well inside the cabin.

Pros:
-The grip is tricky. Most of the time is phenomenal. Grips almost like a sport tyre, especially on curvy roads. But, on a very smooth surface the wheels spin easily when I floor the car in 2nd gear. But the tyre never left me down during spirited driving, I am confident it will stick in the next corner. The grip is still here, and its the same as when they were new.
-Build. Tyre is strong. Its not easy to damage it or bend it. It looks solid. No damage what so ever. After 27.000km it is still a great tyre, with 10-30 grams weights on the balancing machine, it feels like new.
-Wear is good. Most of my driveing is slow, around town with occasional wheel spin just for fun. My driving on open roads is spirited. The wear is only average, but you get a tyre that sticks to the road, not some plastic junk that will slide out of the corner. So I think average treadware is good compromise for great grip and handling.
-Comfort is average. Not too hard, not soft. Like most summer tyres.
-Stability on rain was great, except for this one time, when I got scary aquaplaning at 90kmh for 2 seconds. Now I don't feel so safe anymore :( Maybe its because they are down to 5.7mm.
-Resistance to roll. Economy. The tyre has extremely low resistance to roll. Much much lower than the my winter tyres.
-I don't think there is a better tyre for the money. I'd buy it again. Hope they can fix the noise problem. If they do, it will be the best tyre in its class.

Comfortable and quite tyres with very soft sidewalls. Average handling and feedback.

The tyres came as the standard fit on my fiat 500x. The car is on a company lease so I cannot ditch them. I live in Holland where it rains a lot, the asphalt is generally very smooth and the wet grip is below par for a premium branded tyre. Generally a mediocre tyre really if you were to buy them from your own hard earned money. Dry grip is okay but they don't inspire much confidence in cornering.
I would buy conti or michelin. Not recommended

got to be the best tyres, comfortable quiet plenty grip

Replaced existing Good Year Eagle F1 with these and very pleased. Ride much more comfortable and grip very good in dry and wet.

Horrified. As an ex police driver I was not happy with the hankook the car came with, these goodyear were recommended by the tyre fitter? As an efficient and spirited driver I am mortified by the lack of feel in cornering, combined with a jelly like feel within the entry stage of corner. I cannot afford to replace straight away (pension) but will swap them out the second I have finance.

Lasted 60.000Km on Mitsubishi Grandis. Changed for lateral wear in the end . Changed front backward.
Very low fuel consumption, noise and high confort.
Not for racing.

Fitted to my Skoda Fabia on the front, seemed very good tyres very grippy in the wet and dry especially traction wise. As they wore down below 3mm they started to loose grip and squeal when cornering. The biggest issue with these was despite me inflating them to the recommended 31psi, they wore heavily along the centre tread line and within 7,000 miles they were down to the limits.
Very disappointed. Have replaced with Avon ZV7 which give much more feedback on the limit than the goodyears, hopefully will last a bit longer too.

The Goodyear EfficientGrip Performance tyres give good grip in both wet and dry road. Road noise isn't too bad as the tyre were soft compare to other brand. However they did wear faster then my previous tyres (Michelin).

Fitted to the front of a 2007 Toyota Avensis 2.2 D4D Tourer used for commuting, so leisurely rather than progressive driving in the main! They perform well in both the dry and wet. They are quiet and comfortable. The only downside is that after 18,000 miles they need replacing, which is a disappointment given my driving style. The only other comment is that even when inflated to to recommended pressure, they appear under-inflated.

Tyres performed pretty well. Was surprised how low the tread was when it came time to replace them as they had worn about 1-2mm deeper than I was expecting them to have done after 12 months motorway driving (compared to some el-cheapo alternatives that I had before), but dry/wet grip and stability was much improved.

Can't say I noticed any difference from the A-rated efficiency or noise categories, so have selected the Goodyear Eagle F1's this time around to try instead.

Overall decent tyre, no major complaints.

Perfect tyres
