I agree with Moltuae on Michelin, all I will buy if available.

I've had PS4s on the M4 for the winter - they came on a spare set of wheels I bought with the intention of putting winters on them, but such a mild winter meant that wasn't necessary.

However, the summer wheels are on more or less semi-slick Pilot Sport Cup 2s which were flipping lethal in anything less than perfect conditions, the difference in traction between these and the PS4 is astonishing. If there is anything the M4 can do, it is show up a tyre lacking traction.

So, PS4 highly recommended by me as an all year round tyre
