F1 set for key change to fix dangerous issue

A request from the FIA has been met ahead of the 2024 F1 season

Originally written by Cal Gaunt. This version is a translation.

Formula 1 will introduce new wheel designs in 2024, as a response to the dangerous trend of tyres being dislodged from rims in accidents.

BBS has been the main supplier of wheel rims to teams for the last two years, and have followed the wider F1 community in putting an emphasis on cost reduction.

The larger 18-inch wheels, introduced in the current rules era, have faced challenges with increased forces during impacts, leading to tyre dislodgment.

BBS responded to the concerns by developing an improved MK2 version of its wheel rim design in 2023, gradually introduced after the summer break.

F1 had previously seen issues with tyres becoming dislodged from rims at impact

“The development was initiated in response to a request from the FIA.”

Although visually indistinguishable, the upgraded MK2 rims have undergone significant reinforcement to enhance their resistance to impacts.

“MK2 has no change in spoke shape compared to MK1,” BBS continued.

“Fatigue was not a problem with the original design, but the outer rim shape has been strengthened to better handle side impacts.

“The weight has only slightly increased, but the side impact resistance has more than doubled.”
