Today I added air to our car's tires for the first time.
We've driven around 9500 miles with the car now and last time a warning light for the tire pressure came on just before the service appointment, and I wanted to take action earlier this time.
A week ago or so I bought a tire pressure gauge -a fancy digital one- but the gauge in the air hose at the gas station was much easier to use. For some reason my digital gauge didn't give a reading on two of the tires, only after trying 6 or 7 times it worked.
It cost me $1.50 in quarters because it took a while before I had it all figured out, but now the pressure in all the tires is nicely around 30 psi.
When I drove away from the gas station I could feel the difference, or at least I imagined I could feel it.
