Michelin Malaysia Sepang Tire Comparison Test

For a new tire, the items to be tested include wetland handling, wetland braking, dry control, dry braking, abrasion resistance (tracks and roads), noise comfort, fuel economy and water drift. Combining the characteristics of PSS technology, this test mainly tests the handling performance of dry and wetlands, as well as the noise and comfort experience. The Pilot Super Sport Tire (PSS) released this time is a high-end product of Michelin's Pilot series, which can meet the extreme driving experience pursued by top sports cars and ultra-high performance car owners. As a result, all the test tires are high performance cars, including the Ferrari 458 Italia, the Porsche 911 Turbo, the BMW M3, the Subaru Impreza WRX STI and the Renault Clio RS. Compared with the previous-generation PS2, the newly-listed PSS mainly improves the handling of dry land and wetlands, and the wear resistance of the track is further enhanced.

The listed PSS uses a high-density fiber Twaron coating to ensure that the pre-installed PSS Ferrari 458 Italia has a lower bulge at high speeds, has a good grip, and has good braking power when the brakes enter the bend. The safety of driving on the track. In comparison, Pirelli P was preloaded. The steering wheel of ZERO tires should be lighter. In dry handling tests, the two Ferrari 458 Italia were preloaded with Pirelli P. ZERO Tire and PSS, the testers drove two cars at a speed of over 200 km/h on Sepang Speedway, and the grip became the first assessment indicator.

The PSS composite tread technology also performed well in the wetland piling tests conducted on the Subaru Impreza WRX STI. From the dry ground into the wetlands, the driver will not feel too obvious changes. This is mainly due to the soft, high grip elasticity inside the tread, which can scratch the water film on the wet road surface and ensure the grip. Test results show that in the 2.7 km closed track, the pre-installed PSS tires are 1.5 seconds faster than the pre-installed PS2; in the 4.1 km closed track, the wetland driving time is shortened by 2.5 seconds; wear resistance The number of circuit laps has increased by 50%. Twaron covers ensure the safety of high-speed straight-line driving, but high-speed cornering tends to reduce grip. In order to solve this problem, PSS has adopted a special composite tread technology. The inner side of the tire uses a softer, high-grip elastomer to ensure the grip of the tire on irregular roads such as curves, while the carbon black-reinforced elastomer is used on the outside of the tire. , to ensure the durability of sharp corners.
