Review on Accutire MS 4021R Digital Pressure Gauge by Kevin Webb

I bought 1 for myself then 3 more for my family and friends, this is a must have for car owners in multi season regions. I live in Chicago and in spring and even fall the temperature can vary widely between 24 and 48 hours. I have experienced it being under 30 one day and over 70 the next day. When the weather is this crazy it's better to be safe than sorry so I can inflate my tires to the correct tire pressure. Older vehicles do not have an onboard monitoring system that can measure the pressure in all 4 tires; this is only installed in more expensive and newer vehicles. And most ordinary people don't understand the importance of having the right tires and tire pressures. Tires affect everything from handling, safety and comfort, and tire pressure is a part of that. In addition to handling, safety, and comfort, proper tire pressure can help tires last longer. This tool is so easy to use, you literally push the button to turn it on and then plug/insert into the valve and it will give you a tire pressure reading in psi.
