I know this has been asked a bunch but I need new tires (again) and given the cost of new tires I want to switch my staggered wheels to a box set up.

Costco is giving me a hard time about changing my MYP 21” to 19” wheels.

Anyone know what I need to say or if they’ve had luck here?

FYI: ordered rims from Costco third party just need to get the wheels so they can install both on the vehicle.
