Kimi Raikkonen feels that the current wet weather tyres are not as good as those from over a decade ago.
Raikkonen crashed out of last weekend's Brazilian Grand Prix after losing control in the wet conditions - something he feels was solely down to the Pirelli tyres, whereas if he was using the Michelin and Bridgestone tyres he used during his days at McLaren and his first stint at Ferrari, he feels the outcome would have been different.
"These tyres are very vulnerable, very easy to aquaplane," said Raikkonen.
"Obviously it depends on the circuit, on many things, but if I'm comparing it to 10 years ago or 12 years ago, those tyres could handle this kind of water with no issues, no aquaplaning.
"The aquaplaning is the big issue. It looks like if you have a little bit of standing water there's zero grip."
