cool air for inflating tires

The next time you inflate your tires, take a note of how hot the air compressor gets. That happens because air heats up when it is compressed. If you don't have an air cooler (which can just be a long length of hose), you'll be inflating your tires with hot air, which will then decrease in pressure when it cools down, which means the tires would be underinflated.

Therefore, either let the air sit for a while in the tank to let it cool down before inflating or use an air cooler to ensure you're really getting the correct pressure in your tires. Another benefit is that some of the moisture would be condensed out of the air as it cools, prolonging the life of the tires and reducing pressure variations as they warm up.

I actually have an idea for making an air cooler out of 1/4" copper tubing, a fan, and a compressed air condensation catch can.
