A German magazine is reporting that FIA president Jean Todt wants Michelin to consider returning to formula one.
Pirelli's three-year contract as the sport's official sole supplier ends next season, with boss Paul Hembery indicating that an extension is not guaranteed.
Replying to a direct question on Twitter
about Pirelli's plans for F1 beyond 2013, Hembery said recently: "If they (F1) want us and if the economy stays sane, yes (we will stay)."
Michelin, however, has said previously that it would only consider coming back to F1 - where it competed with Bridgestone between 2001 and 2006 - if the sport ends its current single-supplier rule.
