Review your Pirelli Cinturato P7 All Season Plus II >

I'm reviewing the Pirelli Cinturato P7 all season plus 2. I'm assuming that's the U.S. version of what you call the SF2. If not please delete this review or move it to the right place. They were decent tires when new though I found them to be noisy on course pavement and nibbly on grooved concrete.
The biggest problem with them is that despite having a 70,000 mile warranty they are hydroplaning so badly at 24,000 miles that I have to get rid of them.
In heavy rain they are incredibly dangerous. I've almost lost control of the car twice in the last week so they are coming off immediately. This is on an
all wheel drive Mercedes which is normally a very stable car. And I wasn't even cornering, when I hit water on the road the car would start skittering around in random directions.
