An all-new tyre - featuring the 2012 construction with the '13 compounds - has been evaluated without problems at this week's young driver test at Silverstone.
The fact that there have been no issues, at the same venue where there were four high-speed blow-outs in the British Grand Prix, has left drivers much happier about the situation.
Felipe Massa, one of the men who hit trouble at the Silverstone race last month, is now confident that Pirelli's delamination issues are no more.
"For construction and safety it is better – and nothing has happened here," said the Ferrari driver.
"There were no blow-outs or punctures like we saw in this race. That is the most important thing."
Pastor Maldonado, who tested at Silverstone on Thursday, said that drivers would be happy using the new tyres for the high-speed demands of Spa and Monza after the summer break.
"I think we need to go all together and believe in Pirelli now," explained the Williams drivers.
"They had the solve the problem; they knew where the problem was and here we haven't had anything."
