Lewis Hamilton ended Friday in Malaysia in fourth place, with a best lap some 0.142s off Nico Rosberg.
Like his team mate, Hamilton had concerns about the tires.
“We were just working to understand the tires, which are very, very hot,” he said. “And also just making sure that the balance is right, so you can go as long as possible.
“It’s the same as every time we come here, so it’s to be expected. It’s too hot for the tires. The tires aren’t working very well in these conditions. Even though we’ve got the hard tire and the medium here, the tires do not feel great, but it’s the same for everyone.”
Told that teammate Nico Rosberg didn’t seem happy with his day, Lewis said: “We got through practice and he’s at the front, so it’s kinda weird that he wouldn’t be satisfied with that. Balance wise we are still a little bit away from where we want to be.”
Meanwhile Lewis wasn’t interested in speculating over other teams.
“I don’t have a guess, I’m not really focussed on anyone else, I’m just focussed on my side trying to make sure the car is comfortable beneath me. Hopefully it will go the distance.”Formula 1, Lewis Hamilton, Mercedes
