F1’s wheel rims made stronger to address loose tyre problems
Since 2022, BBS has been the standard supplier of wheel rims for all teams in Formula 1 as part of the FIA’s effort to reduce costs. BBS focused on addressing the challenges faced by larger 18-inch rims, which are more susceptible to damage from side impacts compared to the previous smaller designs. This has led to instances where the tire becomes detached from the rim in crashes. In response to the FIA’s request, BBS developed an improved version of its wheel rim design called MK2 to enhance its strength. The upgraded rims were gradually introduced in 2023 and have been well-received by teams. The new MK2 rims, which appear identical to their predecessors, have undergone significant strengthening to better withstand side impacts, with the weight only slightly increasing. BBS has also improved the coating treatment for better aesthetics.
