Any thoughts from those of you who know way more than I do about this sort of thing?

I will assume the car is outside. And hopefully your daughter regular checks the tire pressure (regardless if equipped with TPMS) and the tires are regularly rotated with a proper alignment.
As such UV as well as oxygen are two factors that cause degradation (apart from driving). My suggestion based on Michelin's and other guidance would be to run them for a couple more years while regularly inspecting the tires.
For reference, my spouse's buggy does not have many miles. It lives in a garage. It has summer and winter shoes. Both are at the 10 year mark. We are running both one more season as there are no visible signs of degradation.
