Hamilton in trouble over rules breach
McLaren have been fined 15,000 euros for using two sets of wet weather tyres during the first day's practice for the Brazilian Grand Prix.
Under Formula One's sporting regulations 'no driver may use more than one set of wet and one set of extreme weather tyres during P1 and P2'.
However Lewis Hamilton, together with Honda's Jenson Button and Super Aguri's Takuma Sato, used two sets of the tyres in damp conditions during the first free practice session at Interlagos on Friday morning.
The other two teams will also have to pay the fine, while the drivers will not be allowed to use the spare set of tyres again during the weekend.
"We did a slow out lap on wet tyres, then came in and went out on another set," Hamilton said. "It was an easy mistake to make.
"A couple of other teams did it, yet we haven't gained anything by it. We didn't do it intentionally. There wasn't any benefit."
Team boss Ron Dennis added: "It was a 100% team mistake. Lewis did an installation lap on one set of wet tyres and we just put on another set. It was nothing to do with Lewis.
"There's a rule there, we broke it, and now we have to get on with it."
The rules infringement means a turbulent start to the GP for Hamilton, who on Sunday goes in search of the world title in his rookie season.
Hamilton leads the battle for the drivers' championship by four points over Fernando Alonso, with Kimi Raikkonen, who emerged quickest from the
opening session, a further three behind.
The 22-year-old later set the fastest time in Friday's
second practice session, with Alonso second and Raikkonen fourth quickest overall.
