In this comparison, we are comparing a tyre from a manufacturer from (Accelera) against a tyre from a manufacturer from France (Michelin). Generally, Michelin summer tyres are slightly better rated (79%) than Accelera (0%). But when it comes to comparing Accelera Phi-R and Michelin Primacy 3, the rating is the same - 0%. The first tyre test of Accelera Phi-R was done in 2017, compared to 2016 when was the Michelin Primacy 3 first tested. Important for this comparison is also the Autobild 2017 225/50 R17 test, where both the Phi-R and the Primacy 3 were tested.
