In this comparison, we are comparing a tyre from a manufacturer from (Hi) against a tyre from a manufacturer from France (Michelin). Generally, Michelin summer tyres are slightly better rated (79%) than Hi (14%). But when it comes to comparing Hi Fly HF 805 and Michelin Primacy 3, the rating is the same - 0%. The first tyre test of Hi Fly HF 805 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 Fly HF 805 and the Primacy 3 were tested.
