Button, Hamilton, Sato under investigation over tyres 19 Oct 2007
Hondas Jenson Button, McLarens Lewis Hamilton and Super Aguris Takuma Sato are under investigation at Interlagos over an alleged breach of tyre regulations in Friday mornings opening practice session.
All three drivers supposedly used two sets of wet-weather tyres, in contravention of Article 25.3 of the Formula One sporting regulations, which states: "No driver may use more than one set of wet and one set of extreme weather tyres during P1 and P2."
Stewards are expected to look into the matter following second practice. It is not yet clear whether the drivers involved will face any penalty.
