Hello! I recently changed my vehicle, from Polo GTI year 2015 to the same, year 2020 The driving performance is practically identical. However, I noticed one thing with a quick “curvenhatz”, and I would be interested in the technical background here, here tire details: Alter Polo: Bridgestone Potenza S002 in 215/45R17 New Polo: Bridgestone Turanza T005 in 215/40R18 I get at the new not as high curve speeds as with the old one annoyed me, I push that the Turanza is less a performance tire than the Potenza. But this is not supposed to be a topic here. However, what interests me is that the Turanza starts squeaking at high speed. At Potenza it never squeaked, at some point he then understeered and there came to the typical “Brrrrr” noise at understeering. Jetzz the question: why does the one tire squeak in the border area, and the other not. And what does it mean from a technical point of view, when a maturity What’s going on, grip maximum, or too fast?
