I've covered 270 miles on the PSS now and I'm very impressed with them! We've had quite a bit of rain here in the UK over the past week and last night it was very heavy. There were large areas of standing water, rivers running along the roadside, etc, but the PSS were unfazed. They cut through the rain as if it wasn't even there. To say I was impressed is an understatement!!
In the dry they are even better. The front end grip feels positive and there is a real "sticky feeling" when they dig in around a corner. I've not fully explored the grip levels yet as I guess I'm still technically running them in, but they are miles ahead of my former Pilot Sport 2s.
As said by a number of people on here, they are highly recommended!
