In this comparison, we are comparing a tyre from a manufacturer from Poland (Kormoran) against a tyre from a manufacturer from USA (Goodyear). Kormoran is a brand that belongs to the Michelin group. Generally, Goodyear winter tyres are slightly better rated (85%) than Kormoran (12%). But when it comes to comparing Kormoran Snowpro b2 and Goodyear UltraGrip Performance Gen-1, the rating is the same - 0%. Important for this comparison is also the Autobild 2017 225/50 R17 test, where both the Snowpro b2 and the UltraGrip Performance Gen-1 were tested. When it comes to comparison, eu labels can be also interesting - 100% of Kormoran Snowpro b2 has E wet grip rating, whereas 88% of Goodyear UltraGrip Performance Gen-1 has B rating.
