Had a flat in the driveway on my 2022 Z21xl with optional 18" wheels. Must have hit a piece of debris-metal on way home a few days earlier so pulled the spare off the trailer hanger. The spare had never been off the trailer since I took delivery in September 2021. I trailer a lot so rig has a lot of miles on it.
When I flipped over the spare, the steel hanger frame had rubbed notches (1/4" to 3/8") the inside of the aluminum rim. Cosmetic and on the inside of the rim but sort of annoying. If you are running the optional rims might be worth a look.
Good luck.
