Spare tire cable.

Can't really figure out the purpose of the spare tire cable especially since the crank down is locked.

It's a safety feature to prevent the tire from falling into the road and being struck by another motorists.  I think all of the truck makes have them.

Must be a new thing as my 2018 1500 did not have it.

The spares are larger and heavier than previous years.
