Michelin Pilot Road 4 Touring Radial Tire - 150/70R17 69V A new silica-rich rubber means the Michelin Pilot Road 4 tire provides exceptional grip no matter the lean angle, at minimum temperatures of -5deg. C on dry roads and 2deg. C on wet ones with maximum temperatures of 45deg. C on all types of roads. With a harder rubber in the middle derived from 2CT technology, the Michelin Pilot Road 4 tire features a 20% longer service life than the Michelin Pilot Road 3 tire. Thanks to its Michelin XST+ Sipes, it benefits from chamfers, which limit uneven wear and tear. Thanks to novel XST+ Sipe technology, the Michelin Pilot Road 4 Trail tire provides for 17% shorter braking times on wet roads than its nearest rival, and 24% shorter times on extremely slippery wet surfaces such as white traffic lines and pedestrian crossings.
