Sainz calls for better Pirelli wet and intermediate tyres

Williams driver Carlos Sainz has called on Pirelli to improve its wet and intermediate tyres after a difficult São Paulo Grand Prix, where all drivers started on intermediates.

Sainz, who also serves as director of the Grand Prix Drivers' Association, said the intermediate tyre remains weak at the rear in mixed conditions, and that the front grip fades once it warms up. He described aquaplaning and a lack of rear grip during the wet running, and said work with Pirelli was needed to find a better tyre.

Sainz finished 19th and team-mate Alex Albon 15th, extending Williams' run without a point to 14 races. Sainz said his car was not the main problem and that the team was simply too slow in wet and dry conditions alike.
