Note that the tyre size I got only comes in 94W loading. I was told that it will have slightly stronger side wall but minimal or no impact on the ride.

In summary, P7 for slightly better handling and fuel efficiency. Primacy 4 for slightly better comfort but less a little in handling and fuel efficiency department. The aquaplaning is also not very good. We are talking minor differences between the two as both are within the same category of touring tyres (not like jumping between UHP or touring)

I am happy with the Primacy 4 for my Golf to be driven around town.
