Pirelli has started testing of its prototype F1 tyre for the 2011 season, according to reports.

Pirelli secured the contract to become the sole supplier to F1 in place of Bridgestone earlier in the summer and has now run a prototype version of its new tyre for the first time in France.

"We've started some initial testing on a GP2 car," motorsport director Paul Hembery told Manipe F1, "and had the first runs at Paul Ricard. It was very successful and we're very happy with the performance of the product for the first test."

Hembery refused to be drawn on who carried out the test but did reveal that company should know soon which car it will use to carry out further testing of its new tyre, with the 2009 Toyota having been mentioned as one possible option.

Current teams will have to wait until the end of the season to sample the new tyres for the first time.
