Pirelli tyre prescriptions and operational guidelines for the 2026 Barcelona-Catalunya Grand Prix.

This document outlines Pirelli's tyre regulations for the 2026 Barcelona-Catalunya Grand Prix, including cold pressure cooling curves, maximum heating times, temperature limits, and camber restrictions. It specifies that tyres must not be swapped from their allocated positions and must not be exposed to temperatures below 10°C or excessive UV. Heating times are limited to 2 hours for slicks, intermediates, and wet tyres, with temperatures measured via IR gun on the tyre surface. Starting and stabilized running pressures are defined for front and rear axles across compound types. Compliance with these prescriptions will be monitored by the FIA during the event, and updates may be issued under document FIA-F1-DOC-062. Regulation B6.1.3.a is cited as the authority for these prescriptions.
