Pirelli, the tire manufacturer for Formula One, confirmed this week its tire combinations for the next four races on the calendar.
The teams are off to Europe for the Spanish Grand Prix at Circuit de Catalunya in Barcelona. The May 10th race will feature both the hard and medium compound tires.
The hard tires are marked with orange side-walls while the medium tires are shown with white.
When Formula One visits Monaco immediately following the Spanish Grand Prix, soft and super-soft tire compounds will be available.
The streets of Monte Carlo will be the first time this year that teams get to use the super-soft rubber.
Canada and Austria will also use the soft and super-soft tires following Monaco.
With the exception of the Malaysian Grand Prix, a soft-medium combination was used in three of the first four races of the season. The medium-hard tire combination was used at the Sepang International Circuit in Kuala Lumpur, Malaysia.
Here is a look at the tire compound combinations thus far for 2015:
Australia: Soft, Medium
Malaysia: Medium, Hard
China: Soft, Medium
Bahrain: Soft, Medium
Spain: Medium, Hard
Monaco: Super-soft, Soft
