No mid-season changes for Pirelli
Pirelli have resisted the temptation to make mid-season changes to their compounds.
Last season the Italian manufacturer tweaked its hard compound tyre midway through the season and they tested an experimental tyre in the build-up to this year's Germany Grand Prix.
However, the new tyre will not be introduced, with Pirelli maintaining the status quo.
"We could have done some changes mid-season this year, but having a season with teams so close together we felt that any changes we made could backfire because maybe one team would find that the change would be better suited to them and may give them an advantage, so we couldn't do that this year," Pirelli motorsport director Paul Hembery told ESPNF1.
"Going forward we have a couple of areas we want to improve."
Hembery reveals that changes may be made heading into next season, but that no decisions would be made just yet.
"In terms of structure and compound choices we're undecided [for 2013]," he said.
"We need to understand how much of a challenge the teams would like because we have to bear in mind that they will go straight into 2014 with a very rapid change in regulations. Maybe they don't want to be challenged so much next season when such a huge challenge is coming the year after. If we did continue in 2014 maybe we would take the opportunity ourselves to do something more dramatic."
