For me, for all year use it's the PS4. I have been so impressed with them. Grip well in all conditions. Superior to the Yokos in the wet. Yokos will grip better in the dry, but if you are getting any benefit from this you're going too fast on the road! I've used PS4 for a few track days too & had no problems in the wet wheras the AD08r users were sliding off. In the dry they were a tad faster, but not night & day faster. I use 215 45 17.
