Pirelli wants to use the services of Pedro de la Rosa for one last time.
The veteran Spaniard, who was the Italian tyre marque's main tester for the development of this year's tyres, has now returned to his former role as McLaren reserve driver for 2011.
But Pirelli has vowed to continue to make improvements to the current generation of tyres and wants de la Rosa to be on duty one last time.
"Our first test is in April and it would be ideal for Pedro to do it before he leaves," Pirelli's Paul Hembery is quoted in Spanish by the as.com website.
"We have made some modifications to the (2009) Toyota and as Pedro has driven it I would like him to compare (the changes)," he added.
