2021 Pacifica Hybrid, less than 500 miles, automatic. Scotty, I mounted a like new 18 inch 55 aspect ratio tire on an an aftermarket 18 inch rim. Pacifica came with 18 inch 60 aspect ratio tires. I know you shouldn't mix different size tires on the same axle, but is this discrepancy in wheel diameter OK since I will use it as an emergency spare only? Thanks!

it's not a huge difference. It should be ok as long as you don't drive too fast or too far with it.

I wouldn’t fret, unless your vehicle has a posi-traction differential, or 4WD/AWD transfer case. You don’t want to have a different tire diameters on a posi-traction axle, or on AWD car.
F.S.
