Ferrari driver Kimi Raikkonen says he struggled with the cool conditions throughout the course of the Canadian Grand Prix weekend.
Raikkonen was able to qualify only sixth and converted his grid position at the finish line, while team-mate Sebastian Vettel led the race and secured second spot.
Raikkonen says that the cool conditions led to problems with getting the tyres into the optimum operating window, a situation exacerbated by the need to save fuel.
"It hasn't been an easy weekend, we tried to make the maximum out of that, but obviously we cannot be satisfied with the result," he said.
"The behaviour of the car was pretty ok in certain parts of the track, but in some others, with the cool conditions, I was struggling with the tyres.
"When I was free to push it felt good, but then when I had to slow down for fuel saving the tyres were losing temperature.
"They were cooling down and it was difficult to make them work again, and this went on for most of the race."
Raikkonen's result dropped him behind team-mate Vettel in the championship.
