The Michelin Power 5 features optimized compounds and improved tread design to offer you the next evolution from the much-loved Power RS tire. Michelin's ACT (Adaptive Casing Technology) is derived from years of racing R&D to bring you a tire that warms up quick and adapts extremely well to a wide temperature range. Front tire utilizes 2CT compounds including 68% silica content in the center of the tire and 16% black carbon on the outer edges. Rear tire utilizes 2CT+ compounds including 55% silica content in the center of the tire and 22.5% silica on the outer edges. A low void Ratio (amount of cuts in the tire) is only 11%, so you have plenty of rubber left to grip the road! Wet performance is improved over the Power RS, thanks to the Power 5's unique tread design with added siping and dimpling. Add style to your ride with Michelin's patented Premium Touch sidewall design.
