What this means for you. Category wins matter more than the overall score when your driving is weighted toward one condition — a wet-climate commuter should follow the wet braking column, while a high-mileage driver should follow wear and rolling resistance. Also check that both tires are actually offered in your size and load rating: performance can shift between sizes, and availability differs between the European and North American markets.
