Michelin first competed in the [[1977 Formula One season]], when Renault started the development of their [[turbocharger|turbocharged]] F1 car.  Michelin introduced [[radial tire|radial tyre]] technology to Formula One and won the [[List of Formula One World Drivers' Champions|Formula One Drivers' Championship]] with [[Brabham]] and [[McLaren]], before withdrawing at the end of 1984.{{Citation needed|date=June 2024}}

The company returned to Formula One in [[2001 Formula One season|2001]], supplying the [[Williams F1|Williams]], [[Jaguar Racing|Jaguar]], [[Benetton Formula|Benetton]] (renamed [[Renault F1|Renault]] in 2002), [[Prost (racing team)|Prost]] and [[Minardi]] teams. [[Toyota F1|Toyota]] joined F1 in 2002 with Michelin tyres, and [[McLaren]] also signed up with the company.  Michelin Tyres were initially uncompetitive but by the 2005 season were dominant.  This was partly because the new regulations stated that tyres must last the whole race distance (and qualifying), and partly because only one top team (Ferrari) was running Bridgestones, and so had to do much of the development work.  Michelin in contrast had much more testing and race data provided by the larger number of teams running their tyres.{{Citation needed|date=June 2024}}

Following the debacle of the [[2005 United States Grand Prix]] where, because of safety concerns, Michelin would not allow the teams it supplied to race, Michelin's share price fell by 2.5% (though it recovered later the same day).  On 28 June, Michelin announced that it would offer compensation to all race fans who had bought tickets for the Grand Prix.  The company committed to refunding the price of all tickets for the race.  Additionally, it announced that it would provide 20,000 complimentary tickets for the 2006 race to spectators who had attended the 2005 event.<ref> BLOUNT, T. (2005, September 23).

Michelin has had a difficult relationship with the sport's governing body (the [[Fédération Internationale de l'Automobile|FIA]]) since around 2003 and this escalated to apparent disdain between the two parties during the [[2005 Formula One season|2005 season]].  The most high-profile disagreement was at the United States Grand Prix and the acrimony afterwards.  Michelin criticised the FIA's intention to move to a single source (i.e. one brand) tyre from 2008 and threatened to withdraw from the sport.  In a public rebuke, FIA President [[Max Mosley]] wrote: "There are simple arguments for a single tyre, and if [Michelin boss Édouard Michelin] is not aware of this, he shows an almost comical lack of knowledge of modern Formula One."<ref>{{cite web |date=11 September 2005 |url=http://news.bbc.co.uk/sport1/hi/motorsport/formula_one/4234936.stm |title=FIA hits out in Michelin tyre row |website=[[BBC News]] |access-date=26 January 2025 |archive-date=4 November 2005 |archive-url=https://web.archive.org/web/20051104101837/http://news.bbc.co.uk/sport1/hi/motorsport/formula_one/4234936.stm |url-status=live}}</ref> Another bone of contention has been the reintroduction of tyre changes during pit-stops from 2006. Michelin criticised the move claiming "this event illustrates F1's problems of incoherent decision-making and lack of transparency".<ref>{{cite web |date=28 October 2005 |url=http://news.bbc.co.uk/sport1/hi/motorsport/formula_one/4385004.stm |title=Michelin attacks new tyre rules |website=[[BBC News]] |access-date=26 January 2025 |archive-date=19 February 2006 |archive-url=https://web.archive.org/web/20060219143008/http://news.bbc.co.uk/sport1/hi/motorsport/formula_one/4385004.stm |url-status=live}}</ref> 

In December 2005, and as a result of the difficult relationship with the sport's governing body, Michelin announced that it would not extend its involvement in Formula One beyond the 2006 season.<ref>{{cite web|url=http://newsonf1.net/2005/news/12/dec14m.htm|title=F1 News - Michelin will not extend its Formula One involvement beyond the 2006 season - Michelin - 14 December 2005|last=((NewsOnF1.com))|website=newsonf1.net|access-date=14 December 2005|archive-date=16 December 2005|archive-url=https://web.archive.org/web/20051216112402/http://newsonf1.net/2005/news/12/dec14m.htm|url-status=live}}</ref> [[Bridgestone]] was then the sole supplier of tyres to Formula One until the end of the 2010 season, with [[Pirelli]] providing tyres for 2011.

The last race won on Michelin tyres in Formula One was the [[2006 Japanese Grand Prix]], [[Fernando Alonso]] benefitted after the [[Scuderia Ferrari|Ferrari]] engine of [[Michael Schumacher]] failed during the race.  This gave Michelin a second consecutive [[List of Formula One World Constructors' Champions|Constructors' Championship]] win, with the 2005 and [[2006 Formula One season|2006]], after Bridgestone's seven-year winning streak, and brought to a total of four the number of titles for Michelin since this championship's inception back in the [[1958 Formula One season]]; Michelin's other titles were in the [[1979 Formula One season|1979]], and [[1984 Formula One season|1984 season]]s.{{Citation needed|date=June 2024}}
