Pirelli says it will define a 'clearer procedure for teams regarding tyre usage' following recent incidents at the Belgian and Italian Grand Prix.

Paul Hembery, Pirelli motorsport director, says the tyre manufacturer is set to work with the FIA and Formula 1 teams at the upcoming Singapore Grand Prix to set out strict instructions on tyre usage. These rules will be applied to ensure the recent spate of tyre failures and controversies are avoided.

At Spa both Mercedes' Nico Rosberg and Ferrari's Sebastian Vettel suffered tyre blow outs which sparked an investigation by Pirelli. The results presented at Monza, which were backed by the FIA, pointed the finger at teams and debris on the track for causing the tyre failures.

However, tyre problems continued in Italy when Lewis Hamilton's victory came under pressure after race stewards investigated Mercedes after one of the Brit's tyres was recorded to be below the minimum tyre pressure recommended by Pirelli.

An new investigation revealed that the left rear tyre was the correct pressure when fitted but lost pressure as it cooled due to the tyre blankets not being connected on the grid.

Despite Hamilton and Mercedes being cleared of any penalties, the variance in results meant Pirelli believed other teams could also be affected and a review of protocols was to be undertaken.

In Pirelli's preview ahead of the Singapore Grand Prix, Hembery has outlined its plan which will be applied to avoid any further miscommunication between teams and the tyre manufacturer.

"During these days we will be defining, together with the FIA, a clearer procedure enabling the teams to more easily follow the rules regarding tyre usage," Hembery said. "This is important to avoid any misunderstandings, by giving the teams more precise indications to comply with, thus avoiding what happened to Mercedes in Monza."
