The tire as a limiting of the World Rally Car 2017

the arrival of The new World Rally Car doesn’t end to convince. The new prototypes that will compete from 2017 have gained in power, but also in grip aerodynamic. This fact along with the return of the center differential, it seems that has caused the new generation of World Rally Car is much faster and more stable, although that lies in that are less spectacular for the fans. However, this increase in performance also has an impact on the tires. The demands of the new machines with the gums will be much higher, something that has alert to Michelin and DMACK.

Even without delving into excessive technical concepts, the new World Rally Car has more power-it also increases the torque and acceleration, as well as a greater grip aerodynamic, which lies in a step-by curve faster. Andhese ingredients increase the wear of the tires, something that can affect the length of the longer stretches and loops, which the pilots usually come out with four decks and two spare in the car. At this point the fear is that the World Rally Car are ‘neutered’ faced with the need to preserve the tires.

In this line, Dick Cormack as responsible for DMACK wrote: “Both Michelin as we know that there will be a greater level of wear and tear, especially in sections of gravel. This means that you will have to change the compound and possibly the pattern of the drawing of the rubber. If we increase the width of the tread, the tire will have a longer useful life, but at the same time, you need to reduce the distance between the slits of the band and that will reduce the grip. The pilot open track may still have less grip and in the end what we want is that in the WRC can go as fast as possible”.
