Pirelli delays revised F1 tyres

LONDON, England -- Pirelli has shelved plans for Formula 1 teams to race with its new-specification tyres at the 2013 Canadian Grand Prix in June on June 09.

The modified rear tyres would now be used only during the first and second practice sessions in Montreal for evaluation purposes, with each team given two sets. The hope is that teams could use them at the 2013 British GP on June 30.

Pirelli said: "The regulations allow us to bring a set of experimental tyres to Friday practice. We decided to do it that way which gives everyone a chance to test them and, we hope, all agree."


Pirelli wants to restructure its tyres to incorporate a 2012-style inner belt made of kevlar, rather than steel, after a spate of failures caused by debris. Its also keen to eliminate delamination - the tread separating from the tyre body without the tyre deflating.

However any change would have to be approved by all the teams, unless the governing International Automobile Federation orders it on safety grounds - which has not been the case.

Red Bull has been vocal in calling for the 2013 tyres to be made more durable to reduce the number of pits tops and allow drivers to race harder. Others such as Lotus, Ferrari and Force India are against the change because their cars are working well with the present compounds.

Pirelli has also come under fire for carrying out a "secret" tyre test in Spain with Mercedes after the 2013 Spanish F1 GP. The matter has been referred to the federation, which could pass it on to its international tribunal, after protests by Ferrari and Red Bull at the 2013 Monaco GP.

Testing is banned during the racing season, hough Pirelli has it written into their contract that they can carry out a number of 1000km tests with a representative car.

Red Bull principal Christian Horner said Mercedes, which won in Monaco, had acted in an "underhand" manner by not telling others about the test. He suggested that team had gained an advantage by running a current car on tyres to be used later in the 2013 season.

Pirelli disputed that, saying Mercedes did not know what it was testing
