F1 set to abandon possible switch to 16-inch tyres for 2026
The FIA considered a smaller rim size for the 2026 cars to reduce weight, but Pirelli opposed it for practical and marketing reasons. The switch from 13 to 18-inch rims in 2022 was seen as a step forward, so reverting back may harm the sport’s image and tech progress. Changing the size would require significant adjustments to Pirelli’s production for testing in 2025 with new F1 mule cars. Teams facing challenges in the new era preferred sticking with 18-inch rims and slightly altering the tyre size and shape. Pirelli’s Mario Isola stated a preference for 18-inch tyres due to performance considerations and managing heat dispersion. He highlighted the complexity of wheel design addressing weight, performance, and driver expectations.
