FIA gets tough on tyre usage

Friday 05-July-2013 09:42

There will be no tyre swapping allowed at the German GP while the FIA will also closely monitor the tyre pressures and cambers this weekend.

The move comes after Pirelli wrote to the FIA requesting that they enforce stricter limits in the wake of the tyre blowouts suffered by several different drivers at last week's British Grand Prix.

There will be limits on tyre pressures and camber angles and the swapping of left and right-hand side tyres has been banned as Pirelli feels it contributed to the tyre failures at Silverstone.

F1 race director Charlie Whiting said: "For safety reasons, we have been asked by Pirelli to ensure that the tyres on all cars are run under the conditions listed below.

"It will be the responsibility of each team to satisfy the FIA technical delegate that the cars comply with the following requirements at all times."

A statement issued by the FIA on Friday read:
