F1 set to abandon possible switch to 16-inch tyres for 2026
The smaller rim size for the 2026 F1 cars was considered to help reduce overall weight, but Pirelli opposed this due to practicality and marketing reasons. F1 recently switched to 18-inch rims in 2022, aligning with the wider car industry trend, making a reduction seem like a step back in terms of sport image and technology transfer. A different tyre size and shape would require major changes to Pirelli’s production for testing with F1 mule cars in 2025, adding to the teams’ challenges in the new era. The recent meeting between teams and FIA discussed retaining 18-inch rims with slight changes in tyre size and shape, nearing finalization according to Pirelli F1 boss, Mario Isola. He stated a preference to stick with 18-inch tyres due to performance advantages over 16-inch ones, as there are several factors beyond weight to consider in tyre design.
