"Within the constraints of safety considerations, which are always paramount, Formula One encourages Pirelli to provide tyre compounds with performance limitations because tyre degradation contributes to the challenge and entertainment of a Formula One race.
"When doing so, Pirelli provides strong guidance to competitors about any performance limitations of the tyres supplied. Competitors should heed Pirelli’s expert advice when setting their race strategy and tactics, and if they do not, it is at their own risk.
"We are entirely satisfied that Pirelli was not at fault for any tyre-related incidents during the 2015 Formula 1 Shell Belgian Grand Prix.
"Pirelli has offered to provide to each car a single set of tyres to last for an entire event. While we know that they would be very capable of it, a race with no pit stops would be less exciting.
"Thank you, Pirelli, for helping us to deliver excitement to Formula One fans!"
