MICHELINR PRO4 Endurance. This tire was designed to meet the needs of riders who place the emphasis on endurance. Thanks to its reinforced protection against punctures and cuts, the MICHELIN PRO4 Endurance combines high performance with outstanding durability. The performance of the MICHELINR PRO4 Endurance stems from the combination of several innovations: Its dual compound tread is designed to ensure exceptional resistance to wear and enhanced grip when leaning through corners. The grey, yellow and red compound employed for the shoulders provides a very high level of grip on wet roads, while the compound used for the central part of the tread delivers greater protection against punctures and impact damage. The combination of the 110TPI casing and bead to bead breaker ply ensures outstanding resistance to perforation and contributes to the tires remarkable durability.
