We have actually a different experience.
Wet or dry, in corners while driving, our Bridgestone Potenza Sport are good (no ice here, so no idea).
Where it seems to be troubled is when driving off at low speeds and full(ish) lock. As if there’s a difference between the car pushing into the tyre in a corner, and the tyre pulling the car.
We can’t really complain though, both in dry and wet it sticks way better (once going) than anything we’ve driven before. Which isn’t surprising, Bridgestone Potenza Sport are objectively good tyres. The one issue with them is that they’re what’s called “summer tyre” in germany (they’d be illegal to drive in winter in germany).
Here’s how they faired:

Always close to the top.
As i said, we do have issues when driving off as well, but in corners they’re like glue. That’s with the 1.5 TSI Xcellence Lux.
