In this comparison, we are comparing a tyre from a manufacturer from Finland (Nokian) against a tyre from a manufacturer from Japan (Bridgestone). Generally, Bridgestone summer tyres are slightly better rated (88%) than Nokian (66%). The first tyre test of Nokian Powerproof 1 was done in 2025, compared to 2021 when was the Bridgestone Potenza Sport first tested. Important for this comparison is also the Autobild 2025 225/40 R18 test, where both the Powerproof 1 and the Potenza Sport were tested. If you wonder where the tyres in question are made, the Powerproof 1 is made in Finland and Potenza Sport is made in Poland/Hungary.
