In places with lousy wet weather that eats rims you won't be stuck with that long. In dry spots in could take a while.
Living in an alpine desert my MA40s sucked until I got enough winter miles on them.
Plus, they'll last a bit longer before the brake track wears through.
In dry spots that can take a very long time with light machined extrusions.
