Qualifying tyres are not returning to formula one in 2012.
Pirelli's F1 boss Paul Hembery revealed a month ago that ultra-fast and sticky qualifying tyres were among the official supplier's ideas about how to maximise its involvement beyond this season.
"In the end for something like that the decision is with the teams. They might say no," he said in August.
Asked by a Twitter follower on Thursday if the proposal was given the green light, Hembery said: "Not for 2012."
