F1: Pirelli announces next set of compound picks

Formula 1 tire supplier Pirelli has revealed the compounds it will bring to the Spanish, Monaco and Canadian Grands Prix.

For May's Spanish race, the Italian manufacturer will return to the hard and medium compounds used at the Malaysian GP in March.

"The [Barcelona] circuit is well known for putting high-energy loads through the tires, while ambient temperatures can also be notable," said a Pirelli statement. "Asphalt roughness is quite high and the tires on the left-hand side are particularly stressed."

For the following two races in Monaco and Canada, Pirelli will bring soft rubber and utilise the super-soft tire for the first time this season.

"Monaco is the slowest circuit on the calendar, which is very twisty with smooth asphalt and also relies heavily on mechanical grip from the tires," the Pirelli statement added. "This makes it the perfect place for the super-soft, with its rapid warm-up [characteristics], to make its 2014 debut.

"Canada is another circuit that is very reliant on mechanical grip, with the race frequently held in cool temperatures. Traction and braking are the main characteristics of the lap, [and] as a result, the soft and super-soft is once again the ideal choice."
