Hi All. This is sort of strange. My low tire pressure light came on and I discovered the pressure was low on the right front. I then checked all pressures and decided to check the spare also. The sticker in the door says the spare pressure is 60 psi. I checked the spare pressure and it's 20 psi, but that tire is very hard. Can it really be 40 psi low? I've never used it yet and I'm the original owner. Thanks for any info.
