In the Australian pre race coverage James Allen was saying Mercedes, Renault and McLaren favour Michelin while the rest Pirelli. He was also saying there are safety concerns that Pirelli can even make F1 rubber as they have never done it before.
1950-1958, 1981-1986, 1989-1991..?
think James Allen meant modern F1 car rubber though technology has changed alot since 91.
Hm, it's possible. The kind of loads the tyres go through would differ, I agree, but I think it would be within their capability. Remember, they do make tyres for other high-performance categories. It's not like they're going straight from the road to the racetrack. I do think that Michelin have the advantage there, though, having only been out of the sport for four years.
