Bridgestone has denied that it compelled McLaren to put Lewis Hamilton on a three-stop strategy in Turkey.
After finishing second to Felipe Massa, Hamilton suggested that McLaren's strategy had been dictated by Bridgestone because the tyre company feared a repeat of Lewis's 2007 Istanbul tyre failure.
But Bridgestone's motorsport manager Hirohide Hamashima told ITV Sport's James Allen that, while Hamilton's tyres were indeed at risk, the company's only request had been that McLaren ensured his middle stint was no longer than 18 laps.
Hamashima said Bridgestone had recommended a two-stop strategy with pit visits on laps 20 and 38.
Instead McLaren opted for three stops, with Hamilton pitting on laps 16, 32 and 45.
"They made us do a three-stop as it was the safest route to go," Hamilton said in the post-race press conference.
"Unfortunately for us, that put us in not such a strong position to win the race."
Bridgestone also confirmed that Hamilton was the only driver to suffer from the tyre problems, which appeared to be a consequence of the high loadings his driving style generated in the long, ultra-fast turn eight.
"These concerns affected no other car on the grid, and we will be analysing the data to see what we can learn from this," said Hamashima.
