Today at a meting of the Grand Prix commission at Motegi, Dorna's Carmelo Ezpeleta proposed a MotoGP spec tire rule for 2008.
A final decision will be made at the Malaysian race, held Oct 19th-21st.
Tires have been a huge issue in this year's championship. Currently Bridgestone, Michelin, and Dunlop supply teams in MotoGP.
Bridgestone has dominated in 2007 and there's been complaining by some of the Michelin riders as to the standard of their tires this year as the company has struggled to come to terms with the new tire regulations. Valentino Rossi, Nick Hayden, Dani Pedrosa, and Colin Edwards have all acknowledged shortcomings in Michelin's race tires this season.
Rossi has been quoted as saying he thinks the fans would rather see racing that takes one tire brand's superiority out of the equation.
Yamaha already announced their intention to race next season on Michelins. Yamaha's Davide Brivio confirmed this to the press at Estoril last weekend.
Michelin has won every MotoGP championship in the four-stroke era and their domination extends to the previous 500cc two-stroke era as well. The French company has won every premier-class Grand Prix World Championship since 1991.
Bridgestone supply the Formula 1 and Champ Car racing series with a spec tire, plus the IRL under the Firestone brand.
World Superbike has a spec tire rule. Those tires are supplied by Pirelli.
