Michelin is always my favorite brand. Well done!
In the USA the OE 18" is Conti ProContact SSR and is a run-flat-like MOE A/S tire. The 19" is more typically a Goodyear Eagle LS-2 run-flat-like MOE A/S. Of course OE tire vendors often change based on periodic best spec-meeting price to the factory, so my MY2018 cited are likely now different. Also not sure what model year is your GLA or AWD/FWD transmission (good to include in your signature block).
The CrossClimate 2 are not run-flat tires as far as I know. That is one major reason why more comfortable, more quiet, and better handling, as well of course those innate Michelin traits.
