Ok, most of you probably already have one, but I thought I'd put together a little post to let everyone else in on what I've been introduced to.
I've known for years that the tire pressure gauges that they put on the pump at the gas stations are a joke. So, I have a couple of those gauges that are about the size of a pen with a clip on them so you can put them in your shirt pocket. Whenever I go to the station to check my tire pressure, I used my own gauge. I was confident that these gauges were fairly accurate. Then, a friend gave me a DIGITAL TIRE PRESSURE GAUGE. So, I went the the station to check my pressure. Just for a little test, I compared the station gauge, the pen style gauge and the digital gauge. The station gauge was 20 pounds under and the pen style was 10 pounds under the digital one. I used the digital gauge to set my tires 1 pound over the recommended pressure. OH MY GOD WHAT A DIFFERENCE! It's like a new car! It's handles so much better and I'm getting 2 to 3 more miles per gallon. Not to mention the smoother ride. If any of you are relying on one of those pen style mechanical gauges or worse yet, on the one at the gas station, ditch the zero and get with the hero. I'm sure sold!
