No tyre tweaks for Formula 1 from Silverstone

Pirelli has reportedly cancelled plans to change the design and specifications of its 2013 Formula 1 tyres for the British Grand Prix and beyond.
The sport's sole tyre supplier had offered to tweak the design and not the compounds of the tyres, by replacing an inner steel belt with a kevlar one, so as to stop the delamination problems seen this year.

Red Bull and Mercedes are the two main teams that find the tyres 'too marginal' and have criticised their use in current form while pushing for tweaks.

But teams like Ferrari, Lotus and Force India are not too keen on the changes as their cars are easier on the tyres in their current form. The change can only effected if there is a unanimous decision by all teams or if the issue is one of safety.

These teams argue that the delamination is an aesthetic problem rather a safety one, as only the tread comes off with the tyre remaining inflated. Last year's tyres would have simply exploded at high speeds which would be more dangerous than this year's tyres.

“Pirelli has announced that there will be no new tyres at Silverstone,” German news agency DPA reports.

Paul Hembery has reportedly said the reason for not debuting the tyre in Britain is because the teams could not test the tyres due properly due to the rain interrupted practice session in Montreal on Friday.

But it is also obvious that some teams are simply against the change.

“From my point of view,” Ferrari’s Stefano Domenicali is quoted by O Estado de S.Paulo newspaper, “changing the tyres during the season is wrong.”

After Paul di Resta ran for 57 laps before his first pitstop in Montreal, Force India sporting director Otmar Szafnauer said to Auto Motor und Sport : “We have had no problems with delaminations. Why should Pirelli change the tyres if we have shown that everything is ok?”

And Spain’s El Pais quoted a Formula 1 team member as saying that teams like Red Bull and Mercedes will just have to get used to the current situation.

“Let them change the geometry of the suspension and improve their aerodynamics,” the source said.
