Pirelli is hoping to rearrange its 2014 Formula 1 tyre test for Vallelunga next month, after plans to run a McLaren at Austin had to be abandoned.
F1's tyre supplier is eager to get ahead with its work for next season's rubber, but the idea of running at Austin before the United States Grand Prix did not get the necessary approval from the FIA.
With McLaren eager to help Pirelli in its work, efforts were made to find an alternative venue and Italian track Vallelunga is now being lined up for a two-day 1000km tyre test on November 11-12.
McLaren sporting director Sam Michael said: "The FIA has not approved it yet, so it is subject to FIA authorisation.
"As it is a Pirelli test, Pirelli has to get the authorisation and they have to tell all the teams."
Michael added that the team's test drivers will be used, and the 2011 car will be run by staff from McLaren's heritage division.
