Sebastian Vettel says his victory in the Canadian Grand Prix justifies his previous comments about the structural safety of Pirelli's tyres.
The reigning world champion had suggested that Pirelli's tyres needed modifying to prevent delaminations that struck in several events this season.
Vettel says his comments show that he was concerned about safety, rather than Red Bull seeking to gain extra performance through modified tyres.
"I think it's pretty simple. The criticism we had or I expressed was not based on performance," he said.
"I think it was based on safety and I'm sure if you ask other drivers, maybe they weren't that strong in the press, maybe they think they have an advantage with this sort of tyre, but we had some occasions this year where the tyre suffered delaminating, the top layer came off for not exactly known reasons, probably debris but you will always have some pieces on the track."
"I think it's not possible to have an entirely clean track everywhere and I think that has been the criteria. Every time I complained about balance or the tyres and their behaviour, every time as I said as well that on that day there were other people doing a better job and first of all we had to get to their level to start complaining about performance but obviously when you say something, it's in fashion, these days to take what you like instead of probably publishing the whole answer."
Vettel also insists that he is not yet focusing on a fourth straight title.
"The championship is still long and obviously I was in a different position last year at this time and I was able to catch up quite a lot towards the end. I had very strong races."
"I think there are so many things that can happen at that stage of the championship, I'm happy to stand on the grid and focus on the race, trying to win, and the rest we will see later on if we are still in a strong position. I think there's enough of you reminding us if we're not, you are there as well."
