Adrian Sutil says Force India's strength in looking after its tires shows there is nothing wrong with the job that Pirelli is doing.
Pirelli came under pressure earlier this year to make its products more conservative after a high number of pit stops at some events. But Sutil thinks that the responsibility for excessive degradation has to be shouldered by teams instead, because his own Force India outfit has shown what it is possible to do.
In Canada, Paul di Resta completed 54 laps on the set of medium tires that he started the race with.
Speaking about the tire situation, Sutil said: "Paul's pace was good and it just shows we don't have a tire problem. Everybody talks about Pirelli tire problems, but it is a good tire – we saw that in Canada.
"We can do one stop if the car is working properly. I think it was a good race for different strategies.I was on a two-stop strategy. I think both would have worked, two-stop and one-stop were very similar."
Force India was one of the team that stood firm against a push by rivals to try and change the tires midseason. Sutil fully supports his bosses' stance, which has resulted in Pirelli giving up on plans to tweak its rubber at this stage of the campaign.
"I don't want a compound change. This is not allowed," said Sutil. "We have rules and you have to respect the rules. So you do not change the rules during the season.
"There is nothing more to say. It's not allowed to have a new compound and there is no danger with the tires. We have no problem with the tires. It's just some teams get on a little bit better with the tires and some others want to change it.
"Let's see what comes out, but I just want the rules to be respected and I don't want a big change of tires."
The only tweak that Pirelli is now planning is to revise the bonding process of its tires to minimize the chance of a repeat of the delaminations that affected a number of drivers earlier this year.
