A number of the biggest teams in Formula 1 have been struggling with excessive tyre wear this season, something that may be a result of their cars carrying heavier-than-average engines.
Just recently, McLaren driver and former world champion Lewis Hamilton stated his belief that rivals have been managing to get their tyres to last for longer than his own team has.
On the back of these comments, the German publication Auto Motor und Sport has claimed that the answer could lie under the bonnets of the McLaren Mercedes AMG and Force India Formula One cars, with the powerful Mercedes V8 engine placing too much pressure on the vehicles' Pirelli tyres.
According to the publication, the engine-maker has already picked up on the issue and is looking to rectify it without compromising on the amount of power its engines deliver to drivers such as Hamilton.
This comes just days after the company announced its intention to carry on supplying Pirelli tyres to F1 through 2013 and beyond.
