BARCELONA, Spain - Pirelli wants to spice-up races by leaning towards soft-compound tyres as the 2015 Formula 1 season progresses.
Having faced intense criticism of its deliberately heavily degrading tyres, F1's official supplier went notably more conservative for the start of the new 'power unit' era in 2014.
Pirelli vowed to ramp down that conservatism for 2015 as experience of the new regulations increased but chief Paul Hembery acknowledged that the target of mainly three-stop races had yet to be achieved.
