The other day my brother bought this civic from a local dealership. I checked the car in great detail on and off the lot and I discovered that the car had a bad valve stem on the spare tire.
Some vehicles are equipped with tire pressure monitoring system (TPMS). The TPMS could be part of the valve stem and could be expensive to replace.
Step 1: Remove Tire
What you should do is find some flat ground and lay the tire down. After doing so you will need to break the bead. Breaking the bead requires a lot of force. My method is to run the tire over with another car. You should be extremely careful not to damage the rim.
