• New design to be tested during practice in Montreal
• Italian manufacturer aiming to make tyres safer
Pirelli is to test a new experimental tyre during the two Friday practice sessions on 7 June ahead of the Canadian Grand Prix.
The Italian manufacturer’s attempts to make its tyres safer in light of a number of failures during the first five races will involve the new rubber being put through its paces at Montreal’s Circuit Gilles Villeneuve.
Delaminations, where the tread has disintegrated and come away from the belt of the tyre, have occurred to drivers including Mercedes’ Lewis Hamilton and Force India’s Paul Di Resta.
At present a steel belt is used, but Pirelli will replace that with Kevlar, as was employed last season.
Pirelli has confirmed the new tyres, in medium compound only, will be trialled in Friday practice, with the medium and supersoft for the race to remain unaltered as per the current specifications.
With each driver to receive two sets of the new tyre on Friday in Canada, it is hoped that, if successful, it will then be brought in from the British Grand Prix onwards.
A Pirelli statement read: “The aim of introducing the new tyre is to prevent any instances of the tread detaching itself from the structure. However, the performance and wear characteristics of the new tyre will not be significantly different, with the aim of keeping up the spectacle and retaining a strategic element to all the races.”
Pirelli is also hoping the new tyre will lead to an average of two pit stops per race as opposed to the four stops per driver in the Spanish GP earlier this month.
The announcement of planned testing follows news that Mercedes and Pirelli are facing punishment from the FIA having conducted an unauthorised tyre testing session after the Spanish Grand Prix.
