Pirelli will trial prototype tyres at Spa


The Formula 1 drivers will all have two extra sets of tyres to run during Friday’s practices as Pirelli are testing a prototype tyre.

Pirelli have announced that the drivers will run the unmarked rubber during FP1 and FP2.

The tyres that will be tested have been modified to deal with “possible consequences generated by accidental multiple impacts on kerbs or other external bodies.”
