Pirelli has delayed the introduction of its revised new tyres for Formula One which were due to debut at the Canadian Grand Prix.
Instead Pirelli has opted to give the teams a chance to use the new tyres in Friday practice in Montreal, while delaying the full introduction of the new tyres until the British Grand Prix, according AUTOSPORT.
The new tyres feature a Kevlar belt, similar to the tyres used last season, in place of the steel example currently in use, and which has been blamed for the delaminations suffered by Felipe Massa, Lewis Hamilton and Paul di Resta in recent races.
However, because Pirelli has not received unanimous support from all the teams for the new tyres ahead of Canada, it has offered a compromise in the form of extra tyres on Friday in order to allow the teams to test the changes first.
It appears that the new tyres will only be made available for Friday morning practice at the Circuit Gilles Villeneuve, with each team getting two sets of the revised tyre for the 90-minute session.
Paul Hembery, director of motorsport for Pirelli, spoke out about the delay in the introduction of the new tyres. He revealed: “We want to get rid of the delamination that we’ve found is caused by cuts in the tyres that were debris-induced, which created a weak spot in the tyre that caused overheating.
“We’ve been able to replicate that now in our laboratories and internal testing and we believe the solution we have will completely resolve that.”
However, he added that it had been difficult to get the teams to agree to the changes.
Hembery commented: “It risked changing the dynamic of the tyre, in terms of shape and deformation for example, so you can imagine there have been a number of teams that have been extremely vocal about wanting dramatic changes and there are a number of equally vocal teams that want absolutely no changes.”
