The tires were put to the test in exercises in wet braking, wet handling, dry handling and comfort against competitors’ tires.
The Pilot Sport A/S Plus, though not visibly different from the original Pilot Sport, contains technology that allows for improvements in all-weather performance, wet grip and tread-life, according to Michelin.
The tire features three specialized rubber compaounds across the tread, helping to elevate a car’s performance in virtually every type of weather, from wet to dry to winter conditions. Directional tread pattern and wet-weather silica compound combine for extreme wet-weather control. The tapered grooves of symmetrical tread design channel water away from the tire’s contact patch to provide excellent wet grip in wet conditions, the company said.
The Pilot Sport A/S Plus tires are the first UHP tires to be backed by a 45,000-mile manufacturer’s limited warranty, Michelin Said.
The Pilot Sport A/S Plus tire goes on sale in the U.S. Sept. 1. It will be available in 59 sizes, 25% more sizes than the previous generation. At launch, the tire will be available in 29 sizes and the remainder will be introduced in March 2009. Complete sizing options will range from 205/55ZR16 up to 265/30ZR22.
Michelin’s other new offering, the Pilot Sport PS2 ZP, is now available for the Corvette C5, C6Z06 as a plus-one fitment and additional sizes for the C6 model in October.
A UHP summer tire, the Pilot Sport PS2 ZP evolves from the Michelin Pilot Sport PS2 family of low-profile, Z-rated tires. The tire offers all the impressive performance characteristics of Michelin Pilot Sport PS2 tires, plus run-flat capability. It also delivers comfort levels similar to those of standard Pilot Sport PS2 tires, while delivering improved cornering control, thanks to an advanced sidewall and variable contact patch technology, the tiremaker said.
The tire features a unique, asymmetric tread pattern and a highly-customized tread compound, to delivers wet and dry performance for crisp cornering and high-speed capability. The asymmetric tread design presents large outer shoulder blocks and continuous intermediate and center ribs to enhance steering response and cornering stability. The inner lining tread design features a higher groove to rubber ratio with wide circumferential grooves and lateral notches that help channel water through the footprint to enhance wet road traction, Michelin said.
