Kimi Raikkonen says he has no concerns that Pirelli's new Formula 1 tyres will hurt his Lotus team's form from the German Grand Prix.
Lotus was among the teams that lobbied against tyre changes for the Canadian GP as it felt the move could hurt its form.
Raikkonen feels there is no reason to worry, as he says the tyres he tested in Canada felt fine.
"They have to do some changes and that is what has been decided," said Raikkonen in Germany. "If they are similar tyres to those we tried in Canada it actually felt better.
"So, I don't know if it is going to be the same but I have no concerns.
"I think we had one run, but it was OK."
Team-mate Romain Grosjean welcomed the move on safety grounds after his scare at Silverstone, where Jean-Eric Vergne's Toro Rosso suffered a blow-out right in front of him.
"I am pretty pleased about how we changed things from Silverstone, when the safety issue was needed," he said.
"It was a little bit too much. When we were behind the Toro Rosso on Hangar Straight and we had the tyre blowing in front of us, it was a bit scary if you imagine at 300 km/h you can have a massive piece of rubber flying to your head."
