The Power All-Season road tire is part of Michelin’s latest generation of performance tires boasting improved grip puncture resistance and rolling efficiency over their old Pro4 range. Its Hi-Grip tread bites into corners better than ever and combined with the Grip Compound rubber the Power All-Season provides 15 more grip on wet or slippery roads and a 5 watt rolling-efficiency boost over the previous Pro4 Service Course tire.
