A proposal initiated by Force India for teams to be given extra sets of tyres for the first part of FP1 from this weekend's Spanish Grand Prix if they ran rookies was abandoned after failing to get the necessary support.
Pirelli has pushed on with making extra sets of more durable tyres available, however, with all teams getting access to them during Friday's first session at Barcelona.
If the plan succeeds in making people run more on Friday morning, then AUTOSPORT understands it could be repeated at other races.
The concept of extra FP1 tyres was discussed further in a meeting of F1's 'Sporting Committee' this week, with teams voting on whether the idea of having tyres that could only be used in the first 30 minutes should be introduced for 2014.
Introducing that rule would encourage teams to run early in the first session, which is something that does not happen frequently at the moment.
The idea of having tyres that teams could only use for the first 30 minutes of FP1 was supported by 10 teams, with only Force India voting against it because it only wanted the rule introduced if there was a rookie element.
The matter will now go to the FIA World Motor Sport Council for ratification in June.
There were further discussions about improving practice sessions, including splitting up P1 into two 45-minute sessions, but this did not receive much support.
* F1 teams also discussed the idea of bigger sporting changes, which included a proposal to hand out a world championship point for pole position. This was rejected wholeheartedly.
