Because vehicles in FE competitions are designed to be light and aerodynamic, and that means those 2 properties play a larger role that in street cars - and both of those favor tall narrow tires.

Plus, ride comfort is not a consideration in a FE competition, so they inflate the crap out of those tires - and that means they can use even narrower tires.
