Vredestein Sprint+ for the Boxster S replacing ~8 year-old Michelin PS2's. I like the Michelins, but I find they start to get slick in the cool and wet after ~6 years or so even at very low mileage. The Michelins were UHP while the Vredestein's are GT, at least according to TireRack. Aside from noise, the Sprint+ are a bit quieter, no practical difference in the back road, roundabout and highway ramp 'tests'
