Pirelli will not introduce new tyres in Britain
10 June 2013 – Formula 1 teams will not race with Pirelli's modified tyre compounds at the upcoming British Grand Prix, with the Italian manufacturer opting against their introduction after inconclusive testing on a wet opening practice day in Canada.
With a series of tyre delaminations striking various drivers early in the season, Pirelli announced after the Spanish Grand Prix that it would be making safety-based tweaks to its compounds. The idea was for the new rubber, fitted with a Kevlar belt as opposed to steel, to be tested in Montreal and raced for the first time at Silverstone.
However, with showers affecting the majority of running last Friday, Pirelli was unable to determine whether or not the changes would have had a negative effect on the pecking order, with the company now set to use a stronger glue to solve its problems.
Although Pirelli, which is yet to extend its contract beyond 2013, may choose to test the modified compounds again later in the season, they are not expected to be raced.
