8 years later, I finally checked my tire pressure on my spare tire inside the Mazda3. Sure enough, while it should be around 60 PSI, it was down around 10-15 PSI.
NOT GOOD if you have to actually use the thing! So do yourself a favour every year when you change back into your summer tires…check the pressure of your spare tire!
This doesn’t apply to awesome people who also carry an air compressor in the trunk of their car. You can just fill that tire up when the time comes!
