what can I use to make my own contraption for flattening car tires?

You can use a manual or air powered car jack and wedge or an air compressor and an inflatable rubber mat to safely and effectively flatten car tires. Alternatively, you can use a car tire pressure gauge to precisely and slowly decrease the air pressure inside a tire.
