The World Rally Championship has extended its control tire deal for another year, before the FIA decides whether to open the series up to other tire manufacturers again in 2012.
Pirelli was the only firm to bid for the next three-year contract – running from 2011-2013, but after a period of further negotiation between the FIA and Pirelli, a single-season solution has been reached.
A source close to the FIA said: "Obviously, it came as quite a surprise when Pirelli's was the only bid for the next three years. What's happened here is that the FIA has another year to decide which way to play the control tire scenario for the World Rally Championship."
Pirelli won the current contract to supply all tires to the WRC in 2007, with a $14.6m investment in the series, which includes paying for five drivers from around the world to compete in six rallies in the Pirelli Star Driver program.
