It's a 2019 that's likely been in service since 2018, thus it's closing in on 5 years of age. Poop happens. A wheel specialist will make quick work of this issue.

I believe you may have found the most probable cause.......... the wheel balancer from adjusting the wheel on the mandrel.
This tire set has been installed 2 years ago and this corrosion started about a year after on only one wheel. Now, this is on all four at different stage, the one pictured as the worst.
