Starting this season, F1 cars will run on in-house-designed rims. After a variety of solutions surfaced during last week’s first test in Bahrain, expect the teams to compete in this important area as well. Here’s why.
Since 2022, F1 utilized standardized 18-inch rims supplied by BBS to all teams until the last season. However, with the new regulations this year, teams have regained their freedom to design and develop their own rims. While some teams choose to manufacture their rims, most rely on external manufacturers based on their designs. The initial aim of standardization in 2022 was to enhance aerodynamic efficiency by promoting cleaner airflow around the wheels, aiming for closer and more exhilarating races. Now falling under the Open Source Components (OSC) category, rims allow teams to reintroduce creativity and integrate this aspect into their aerodynamic strategies. Additionally, teams are constantly monitoring each other in various areas, including the compression ratios of internal combustion engines, as the competition might expand to encompass rims and brake ducts, pivotal for tire management. The importance of team-designed rims was emphasized by Pirelli Motorsport director Mario Isola after the Bahrain testing phase, highlighting their significance in heat transfer to the tires and the impact on performance sensitivity. Teams are anticipated to continue exploring innovative solutions in the realm of rims to optimize tire temperature, especially in challenging conditions like those at Bahrain, and previous experiences of extreme solutions prior to standard rims era are indicative of potential future developments.
