Oddly enough, the “new” Prius my dad has as a cab uses a full-size spare, instead of a donut spare but it’s a rotted-out Michelin on it. I might throw a cheap LingLong or Leao on that and mark down a replacement date on the B-pillar or elsewhere. Toyota did make a full-size spare an option on the 2016-2022 Prius, standard on their trucks, but the trucks have a 5th TPMS sensor in them.
I don’t normally use Chinese tires, but I’d take Chinesium to take me to safety than a donut spare/“comfort kit”.
