Generally, Firestone summer tyres are slightly better rated (70%) than Nokian (66%). The first tyre test of Nokian Powerproof 1 was done in 2025, compared to 2023 when was the Firestone Firehawk Sport first tested. Important for this comparison is also the Autobild 2025 225/40 R18 test, where both the Powerproof 1 and the Firehawk Sport were tested. If you wonder where the tyres in question are made, the Powerproof 1 is made in Finland and Firehawk Sport is made in Italy.
