Do you know how hard it is to find used tires + wheel combo on marketplace when they are all 5x4.5. Not to mention the only few 5x100 i manage to find are either oversized suburu that rubs my wheelwell or more than half, dont extend far enough to not scrape the brake caliper. Q_Q All other toyota models have made the switch a decade ago. It took till gen 5 to finally decide maybe prius can benefit from a larger selection of tires. Just curious, but is it possible to swap a 5th gen wheel barring to a 3rd or 4th gen? Not that i would attempt it, but hypothetically. Asking for a friend.
Toyota has always tried to make as much as possible exclusive to their company. It's the same kind of stupidity as thinking placing massive tariffs on every country in the world is good for business. It's not, it's never been. Its best to compete at the same level as everyone else rather than exclusifying everything to death.
