Different Sized Spare Tire

My wife’s 2023 ORP came with 20” wheels and tires. I’m assuming they were installed by the dealer. The spare tire is 17”, I know you can’t mix tire sizes in 4 wheel drive but what about on dry pavement just to get home using 2 wheel drive and no locked differential?

 

Even though the metal wheels might be a different size, the overall diameter of the wheel + tire may be the same and you don’t have to worry.

Worst case, plenty of vehicles out there making do with much smaller donut spares temporarily so you can limp around just fine.

 

Makes sense, thanks for your help.
