The Michelin rumour gained strength at the weekend at Spa-Francorchamps, when Friday practice was marred by more punctures.
Aug.26 (GMM) Michelin has confirmed it is poised to return to Formula One.
The sport's existing tyre supplier, Pirelli, has said a 2014 tender at this late stage would be "farcical".
The Michelin rumour gained strength at the weekend at Spa-Francorchamps, where Pirelli's fraught and highly-controversial season took yet another turn, when Friday practice was marred by more punctures.
"Our position is now known," Michelin's competition boss Pascal Couasnon on Monday told Le Figaro.
"If they (F1) are willing to talk, we are ready to do so.
"There must be a time when it is no longer possible -- we still need the physical time to produce tyres. By the end of October, it may be too late."
But he made clear that Michelin, who wants to supply 18-inch tyres rather than the current 13-inch ones, is not simply willing to step into Pirelli's shoes.
Couasnon also said he is no fan of F1's new era of deliberately heavy degradation.
"How F1 is presented today I do not like it at all," he admitted. "It disappoints me and even makes me almost angry.
"F1 is not about changing a tyre after a few laps, we offer a beautiful image of an important product for the automotive industry."
