As the technical partner of Porsche’s endurance racing programme, Michelin played its part in the development of the new Porsche 919 Hybrid by designing specially-adapted tyres for the LMP1 class prototype. In compliance with the 2014 sporting regulations for the FIA World Endurance Championship (FIA WEC) and Le Mans, tyres are size 31/71-18 on both the front and the rear. Developed on a simulator for all of the firm’s LMP1 partners, the Michelin tyres on the Porsche 919 Hybrid were refined during testing sessions conducted jointly between the two firms’ technical teams.
