Felipe Massa insists he is not the only driver struggling with Bridgestone’s tyres in 2010.
After his 2009 accident and return to the grid this season, the Brazilian has had a high-profile struggle to keep up with Ferrari newcomer Fernando Alonso.
But Massa, 29, has played down any link between his difficulties and his recovery from head injuries, insisting his only problem is Bridgestone’s harder compounds.
"I have even tried changing my driving style to get them working faster and better," he is quoted by Portuguese-language Globo Esporte.
"Everyone talks about me, but many, many drivers are having the same problem," added Massa, the 2008 championship runner-up.
He admits that Ferrari in general has also had a difficult season so far, but thinks recent developments have made the F10 much more competitive.
"I think we can be optimistic for the second half," added Massa.
