Based on my experience, the tyres performance wise were alright. On ice or snow - worse than the worst winter tyres, and probably better than the best summer tyres. Overall it wasn't too noisy.
But they have worn down very badly in only 1.5 years during which they did only 15k miles.
Imagine that: time zero - getting new tyres installed.
time +1.5 years - visually the thread is looking low.
time + 1.8 years - MOT warning (still a pass).
Those tyres did not last long at all. Run from them. I do not recommend.
Maybe for other cars it's a different story, but based on my experience - run.
I will never buy this again, and I will attempt to look away from Bridgestone altogether.
That said, other inspected brand (different tyres, different car) has it's own different problems, so you have to choose which negative you can take.
