Dropship orders will be Cancelled ** The Power Cup 2 from Michelin is a tire designed for 95% track use with DOT approval for the street. Dual compound construction puts a denser, more robust tread compound to the ground to cope with aggressive brake and throttle application while a softer compound increases grip at the tire's shoulder. The tire's groove ratio is less than 5%. Michelin tuned the Power Cup 2 for safe, predictable use with or without tire warmers. Warm-up periods are short. Add tire warmers to reach the Power Cup 2 Tire's upper limits of grip even sooner. Handling is communicative with little to no specific setup adaptations required. Adaptive Casing Technology (ACT) matches these high levels of dry grip with predictable response from the carcass and sidewall at all angles of lean. Put simply, the Michelin's Power Cup 2 is a treaded version of Michelin's Power Slick 2 non-DOT racing slick.
