Anyone with PS4S all round validate this experience?
I've done around 6hrs of motorway driving today and compared to the CSC6 (which in turn were noticeably quieter than the PSS and offered more grip in these type of weather conditions), they are quieter still, and more comfortable on all motorway surfaces. The rear end especially feels much more compliant. This is kinda weird since the sidewall of the CSC6 on the rear was more curved than the flatter sidewall of the PS4S. The front PS4S sidewalls are even flatter still.
I know the PS4S has a number of different compound types between inner, middle and outer treads, so perhaps this plays a roll in it?
Anyway, very impressive level of comfort, and the faster you go the more relaxing and compliant they get. Now instead of hearing tyre noise against tarmac when just cruising, I can hear the resonance of the air inside as the road noise echoes (in a good way).
So comfort/performance is certainly ticked off, I imagine they will only get better after a couple more hundred miles. Let's see how long they last.
