SSM 51381 - 2021-2023 Various Vehicles - Tire Sidewall Wavy/Indentation Appearance

Some 2021-2023 Ford and Lincoln vehicles may experience a tire sidewall wavy/indentation appearance in the radial direction on one or both sidewalls. Sidewall wavy/indentation appearance is a common cosmetic characteristic of radial tire construction and will not affect the performance of the tire.

There must be enough complaints coming in about this for ford to issue an SSM… This issue is likely due to the length of time a vehicle was stationary in a yard or lot somewhere awaiting parts and/or transport to its final destination.

Or poor vendor quality controls allowing poorly made tires to make it to the assembly line…
