Pirelli's Paul Hembery says they are changing tyres to benefit the majority of teams
F1 tyre supplier trying to take a "neutral" approach

Pirelli's Paul Hembery has told Sky Sports News that it was their decision to modify tyres for the Canadian Grand Prix in the interests of the majority of teams.
The Italian company announced on Tuesday that it would introduce more durable tyres in time for next month's race in Montreal in response to Sunday's Spanish Grand Prix, which was criticised for its total of 82 pit stops.

Ferrari's Fernando Alonso won the race after making no fewer than four stops - more than Pirelli aim to induce - while World Champion and current leader Sebastian Vettel struggled with his car's tyres on the way to fourth place.
Vettel's team, Red Bull, have been critical of Pirelli's tyres so far this season but Hembery said the decision to make a change came after taking all of the teams into account.
"In terms of (Red Bull Team Principal) Christian Horner, I think we've spoken for about five minutes on this subject," he said. "It's really a Pirelli decision; we have to look at all the teams and the situation as we see it going forward and that's the basis for the decision."
While some teams like Red Bull and notably Mercedes have struggled to make the tyres work, others like Ferrari and Lotus have fared better - something Hembery acknowledged.
"You're not going to please everybody and that's a factor. People will point out Lotus and Ferrari and say that, from their point of view, things are OK," he said.
"But Red Bull have still won two races this year and are leading the Championship. So they haven't been doing too badly, even with the current product.
Hembery stressed: "We have to make a decision based on the data we acquire from all 11 teams. Of course, you may get a team that will prefer an approach more than another. But we try and take, let's say, the most neutral approach to making our decisions so it's best for the majority."
Pirelli hope the fact the new tyre will have a construction similar to last year's means that teams are better able to react to the change.
The 2012 tyre had stiffer sidewalls, which caused its shape to change slightly less under aerodynamic loads than its successor.
"We're going to give teams a lot more data tomorrow," Hembery said. "We're finalising the precise specification. Really, it's a little bit of a mix of what we've been using this season and some of the structural stuff we had last season - which will help minimise the impact for the teams.
"As you can imagine, there's a lot of work to be done on aerodynamics and tyres can impact on that - the way they deform - so teams will be keen to have that data asap so they can all start working towards Canada.
He added: "From an aero point of view, that can have an impact. That's why we'd like to give them something that they've used a little bit in the past - so they've already got some data.
"It's also probably as well the way the compounds will work with the car: they'll be less aggressive from some points of view which will slightly modify the strategy of how they use the tyres during the race."
