The International Motor Sports Association (IMSA) says that Michelin will become the “Official Tire of IMSA” in its premier series – the IMSA WeatherTech SportsCar Championship and its two major Challenge series – beginning in 2019. This nudges aside Continental – the oldest tire maker in the world after eight years of unstintingly popular acclaim from teams and drivers. So the Business of racing and the politics of racing appears once again.
The multi-year agreement calls for Michelin tires to be on every Prototype (P) and GT Daytona (GTD) race car competing in the WeatherTech Championship in addition to its continued participation in the GT Le Mans (GTLM) class. The GTLM class will continue to be open to multiple tire manufacturers.
