I was one of the lucky ones that never had a problem with my OEM Primacy's. I got 55,000 miles out of them! All kinds of tire goo on them. Considering the amount of high speed driving training I have had in Crown Vics, I have never once over driven those tires, or felt I needed a grippier tire. I never babied them! I pushed them hard. That is until the point where 95% of the tread was gone. If I was looking for another all season tire, those would be my first choice. They cost about $30 cheaper each than the Pilot Super Sports. If that helps.
