Tyre Specification

Chapter: C10

In Simple Terms

The tyre supplier (Pirelli) decides what tyres F1 cars use, but they need FIA approval. These specifications can't be changed during the season unless the FIA deems it necessary for safety reasons. Think of it as a locked-in agreement to keep competition fair.

Tyre supplier determines specifications in agreement with the FIA
Specifications remain fixed throughout the season for competitive fairness
FIA has emergency authority to change tyres mid-season for safety reasons
Changes require Formula One Commission approval, except in safety situations

Official FIA Text

Tyre specifications determined by tyre supplier in agreement with FIA. Specification cannot change without Formula One Commission agreement, except FIA may change for safety reasons during season.
