Published a later than usual due to covid travel restrictions, the Polish magazine "Motor" have tested ten 225/55 R17 summer tires in the usual array of wet and dry testing.
The 17 inch size tested can be found on a wide range of vehicles, such as the Audi A6, BMW 5-Series, and Mercedes E-Class, smaller vehicles like the BMW 3-Series and Mini Countryman, crossovers like the Honda CR-V, Nissan X-Trail and Skoda Karoq, and even minivans / people carriers like the Chrysler Voyager, Fiat Scudo and Opel Vivaro.
Motor Magazine used a BMW 5 Series for the testing.
Dry
As with most tests including the Continental PremiumContact 6, the German tire did exceptionally well in the dry, having the shortest dry braking, fastest dry handling lap and the best subjective dry handling feeling. The Goodyear Eagle F1 Asymmetric 5 kept the Continental honest in the braking and the timed lap, and the Nokian PowerProof, Bridgestone Turanza T005 and Laufenn S Fit EQ+ performed well.
Unfortunately while the Pirelli Cinturato P7 Blue was rated as one of the best tires in the dry subjectively, it had a lack of grip in braking and handling.

Wet
The wet grip tests had a very similar order to dry, with the Continental tire leading the Goodyear in both braking and handling tests, the Nokian and Bridgestone also performing well, and the Pirelli having a surprisingly disappointing result for a premium tire.

The deep water straight aquaplaning test had a surprise win for the Imperial EcoSport 2 budget tire, where as the Goodyear proved best in curved aquaplaning.
On balance, the Goodyear Eagle F1 Asymmetric 5 had the best balance between the shallow and deep water testing.

The rolling resistance test perhaps highlights why Pirelli struggled in the grip tests, as the P7 Blue has a significantly lower rolling resistance than even the Bridgestone Turanza T005, which usually has the lowest rolling resistance on test.

Unsurprisingly the budget tire is the cheapest tire on test, with the Pirelli tire offsetting it's low fuel use with a very high purchase price!
Good handling in all conditions (light understeer appears in high-speed corners on wet surfaces, but overall the tires provide a fairly high level of grip), good level of comfort, high resistance to aquaplaning.
