Pirelli has responded to criticism of excessive tyre wear during Sunday's Belgian Grand Prix by claiming that it officially requested a limit on tyre use.
Ferrari's Sebastian Vettel, who suffered a right tyre blowout late in the race, was one of those to launch a scathing attack on the tyre manufacturer, asserting that "this sort of thing keeps going around but it's not acceptable" and that "just out of the blue the tyre explodes".
Vettel was running a one-stop strategy in the race, a tactic which surprised Pirelli motorsport director Paul Hembery who said that he thought it was definitely a two-stop race, with some teams even going for three stops.
The manufacturer has now released an official statement on the matter, asserting that they had asked for a limit on tyre usage to be put in place.
"Regarding what happened today at the Belgian Grand Prix, Pirelli underlines that: In November 2013, Pirelli requested that there should be rules to govern the maximum number of laps that can be driven on the same set of tyres, among other parameters to do with correct tyre usage. This request was not accepted," the statement read.
"The proposal put forward a maximum distance equivalent to 50% of the grand prix distance for the prime tyre and 30% for the option. These conditions, if applied today at Spa, would have limited the maximum number of laps on the medium compound to 22."
