Let me put it into context for you, dear.
Having tried 4x sets of Eagle F1 on 3x different cars, and 5x sets of MPS2/MPSS on 4x different cars, along with knowing the owners of the cars throughout that time along with their driving style compared with mine, every single time the Michelin lasted longer in a rough comparison than the Goodyears.
Does that make the new tyres automatically longer lasting? Of course not. I’ve never said it did. What I’m using is previous historical first hand evidence to produce a reasonable hypothesis, it’s totally up to others to produce a scientific study if they do choose. For absolute clarity, as I’ve said to you many times, I’m sure the new Goodyears are excellent tyres and I’d love to try them.
Have you tried them yet? Or the MPS4/MPS4S?
