Pirelli confirms 2014 tyre size not changing

Pirelli has confirmed reports that the size of its Formula 1 tyres will not be changing, after it was suggested that because the torque produced by next year’s new V6 engines will be much greater, the Italian marque wanted to supply bigger and wider tyres.

Indeed, motor sport boss Paul Hembery told Germany’s Auto Motor und Sport that the 2014 data supplied by one engine supplier in particular – believed to be Mercedes – was “alarming”.

This ties in with reports that Mercedes’ 2014 (engine supply) rivals, Renault and Ferrari, might be expecting to be outpaced at least initially by up to 100 horse power and therefore want the specification of next year’s tyres to stay the same.

AM&S correspondent Michael Schmidt reasons that the FIA and Bernie Ecclestone also argued against the introduction of bigger tyres, despite Mercedes’ preference.

“No matter who it is, nothing hurts business more than a superior package,” said Schmidt.

Hembery confirmed: “Based on the information we have received from most of the teams, we have decided to keep the same tyre dimensions [the same].

“But as the cars of next year will make very different demands of the tyres, we have proposed that the regulations be amended so that the teams may use different compounds front and rear, should it be necessary.”

McLaren’s Martin Whitmarsh reportedly argued that bigger tyres would have required teams to design and produce different gearboxes, due to the increased load on the drivetrain.

But he said work on the all-new, 2014-spec 8-speed gearboxes is now too advanced.

“That work [on the 2014 gearboxes] is now all but complete because, next to the chassis, it’s the component with the longest manufacturing lead time,” said Whitmarsh. (GMM)

    So the FIA has spoken after Renault and Ferrari were on the phone as for Martin Whitmarsh his opinion states that now the gearboxes are almost finished it would be a major re do for all the teams. The reason being Pirelli wasn’t given the information that they were doing the Tyres and they didn’t have the data to design the correct size of tyre to cope with the torque so now the only way forwards with the same diameter is to allow the teams to mix match the tyre compounds. This is another balls up how F1 manages to put on a race is unreal.
