Pirelli has opted for a further delay in releasing its modified tyre compounds, following an inconclusive test of the tyres during a weather-affected Friday practice at last weekend’s Canadian Grand Prix.
The Italian tyre maker had opted to fully introduce its updated tyre compounds at the British Grand Prix, which were designed to reduce the spate of tyre delaminations seen at previous races. The new construction sees the tyres fitted with a Kevlar belt – as opposed to steel – were to be tested in the opening practice session at last weekend’s Grand Prix in Montreal.
However, with persistent wet weather affecting the day’s play, the lack of dry-tyre running meant Pirelli was unable to determine whether the changes would prove worthwhile, or whether it would alter the pecking order – a concern raised by several teams who had benefitted (or suffered) with the 2013-spec tyres.
It is understood that Pirelli may opt for further testing of the new-construction tyres later in the season, although it is not known if these Kevlar-belted tyres will ever be raced.
