In this comparison, we are comparing a tyre from a manufacturer from Finland (Nokian) against a tyre from a manufacturer from USA (Goodyear). Generally, Goodyear summer tyres are slightly better rated (78%) than Nokian (66%). The first tyre test of Nokian Powerproof 1 was done in 2025, compared to 2022 when was the Goodyear Eagle F1 Asymmetric 6 first tested. Important for this comparison is also the Autobild 2025 225/40 R18 test, where both the Powerproof 1 and the Eagle F1 Asymmetric 6 were tested. If you wonder where the tyres in question are made, the Powerproof 1 is made in Finland and Eagle F1 Asymmetric 6 is made in Germany.
