Each year, the wonderful Swedish publication Teknikens Värld performs a summer tire test in Sweden. Their 2020 test covers ten 225/50 R17 summer tires, including the first test of the brand new Goodyear EfficientGrip Performance 2!
The unique Swedishness of the test means they don't perform dry handling, but instead the "moose test" which involves a sharp lane change at speed. Sadly, we can't database this, but you can see the results of the test in the commentary at the bottom of the page.
Other points of note is the fuel use isn't the usual rolling resistance of the tire in kg/T, it's instead the estimated litres per 100km used by the test Volvo, and they give a subjective comfort score which looks at noise and comfort levels, rather than the usual external pass-by noise!
Dry
In the dry braking, the Michelin had an unusually big advantage over the rest of the tires, stopping nearly a meter sooner than the second placed Goodyear EfficientGrip Performance 2!
Dry Braking
Spread: 2.61 M (11.7%)|Avg: 23.67 M
Dry braking in meters (Lower is better)
Dry Braking: Safety Impact: Best vs Worst Tire
Wet
Wet braking was won by the Continental PremiumContact 6. Second place was again awarded to the new Goodyear EfficientGrip Performance 2, with the dry braking champion, the Michelin Primacy 4, having to settle for seventh.
Wet Braking
Spread: 3.94 M (15.3%)|Avg: 27.41 M
Wet braking in meters (Lower is better)
Wet Braking: Safety Impact: Best vs Worst Tire
The new Goodyear was fastest over the relatively short wet handling lap, while the Michelin proved braking and handling results don't always match, finishing second in this test.

Environment
Subjectively, the Michelin had the comfort advantage, which combined internal noise and how comfortable the tires felt when driving. The Goodyear and Pirelli were best of the rest.

Estimates based on typical driving conditions. Rolling resistance accounts for approximately 20% of IC vehicle fuel consumption and 25% of EV energy consumption. Actual savings vary based on driving style, vehicle weight, road conditions, and tire age. For comparative purposes only. Lifetime savings based on a 40,000km / 25,000 mile tread life.
With the exception of economy, the complete absence of positive aspects - you expect more from the tire of this brand. The longest braking distance on dry and wet surfaces, poor wet handling, low comfort.
