This is a link to the whole tire test that convinced me I wanted the Eagles. Below is the section on them.
First Place - Goodyear Eagle F1 GS-D3
As an all-around high-performance tire, you can't beat this Goodyear. It was the best performer in all three wet-track tests and was very competent in the dry. It generated 0.94 g on the dry skidpad, only 0.01 g off the first-place BFGoodrich and tied with the Yokohama and Hankook.
The Goodyear gripped so well that you might not have been certain the road was wet, and it lost traction in a gentle, predictable manner. It held onto the wet track with 0.82 g of stick, an impressive figure considering the worst tire in that test made only 0.67 g.
The Eagle F1 got a lot of favorable comments. In the wet, Geswein called it "direct"—a way of saying the tire provided clear signals about its contact with the pavement.
There were tires that performed better in the dry, but the Eagle wasn't far off. It was a little less precise than the BFG and Yokohama on a dry track, but not by much. And like the Continental, the Goodyear had a high 280 tread-wear grade. At $145 each, it's $34 cheaper than the most expensive tire here.
One thing to keep in mind about the imprints we carefully obtained is that a tire's contact patch changes dramatically as it is loaded, so these prints are not accurate representations of the amount of rubber that each tire puts on the road while cornering or braking.

* The number, which in the case of these tires ranges from 90 to 94, is the load rating of the tire. The higher the number, the more weight the tire can carry. The letter is the speed rating: "W" for up to 168 mph and "Y" for 186 mph.
