Pirelli motorsport director Paul Hembery believes a lot of the criticism aimed at them this season has been unjustified.

The tyre manufacturer has come under the spotlight this year, following a number of tyre failures, most noticeably those experienced at the British Grand Prix, which in turn has led to changes being made to the rubber that teams will use in Budapest this weekend.

Speaking to in an interview with ESPN, Hembery added that one of the main problems with F1 is too much self-interest.

"I think for a large part of the season - and let's take out Silverstone from that - then we feel it's been very unjustified a lot of the comments and it's made a lot of people [at Pirelli] unhappy," he stated.

"People have wanted to use our name and sully our name for their own personal gain and that's unacceptable.

"But anybody seems to be able to say anything today in F1, there's no check and balance, people aren't looking at the bigger picture and there's too much self-interest. That's something that people really need to have a good hard look at because there might be a lot of people looking at the way that we've been treated and thinking 'We don't want a bit of that, imagine us in that situation'.

"So you have to be careful, we're a big company and we want to stay in F1, we're trying everything we can to do the best job we can but we'll be around.

"In other forms we've been involved in motorsport for 110 years - that's longer than any of the F1 teams - and we'll be in motorsport probably for another 100 years when they've all gone, so we'll carry on."
