Michelin has not denied rumours it might be shaping up to succeed F1's increasingly frustrated and out-of-favour official tire supplier Pirelli.
Indeed, some reports have even hinted that the French company's candidature is being championed by FIA president Jean Todt.
But Pascal Couasnon, Michelin's competition boss, said the marque would not consider returning to F1 simply to rescue the sport amid its Pirelli crisis.
Asked, however, if he can categorically rule out coming back to the pinnacle of motor sport, he told Speed Week: "No.
"We all live in the same world, and it is clear what formula one is in terms of visibility -- in this area formula one is a long way ahead. Also when it comes to technology, this (F1) could be extremely interesting," added Couasnon.
However, he insisted that Michelin would not simply decide 'yes' and push ahead with an F1 foray.
"We would be willing to sit down and make some suggestions," said Couasnon, indicating that Michelin would like to change some of the rules.
Asked what he meant, he explained: "In terms of the type of tires in terms of visibility, and what is the right mix for the spectacle and the challenge for tire manufacturers.
"We might suggest, for example, to change the tire dimension for formula one. Today in F1 there are 13 inch wheels, but that doesn't interest us. 18 inches is a whole other thing," he said.
Couasnon also indicated that the current rules do not fit with F1's moves to become more 'green'.
"A tire that lasts only seven laps is difficult to relate to the idea of 'green'," he said.
"We would only be interested (in F1) if we are able to have smart regulations in terms of the tires. It is not enough to return as the 'saviour' of formula one. If there is another way, then we could say 'why not?'" added Couasnon.
