Pirelli, sole supplier to the Formula One Championship, has been completely transformed their range of tyres for the rapidly approaching 2017 season, with new sizes (305/670-13 at the front and 405/670-13 at the rear) as well as new profiles, constructions and compounds.
The compounds in particular will make use of entirely new materials and a completely fresh design philosophy.
After a very positive testing programme with the new sizes last year, Pirelli has decided to additionally homologate a back-up compound alongside each of the five new base compounds.
These extra compounds are formulated using more traditional criteria compared to the new base compounds but will only be introduced later in the season if needed.
“For the first part of the championship, only the new-generation base compounds have been selected,” Pirelli said in a statement. “The back-up compounds could be introduced later in the season to respond to any particular requirements once the real performance levels of the 2017 cars have been identified.”
