Digital tire pressure gauge makes readings easy

My bet is that you don't check your tire pressures as often as you should. And you have all kinds of justifications (excuses) for not, such as the inside dual valves are hard to get to, there was someone waiting behind you at the gas station and you had to move before you had time to check the presssures, and the gauges have such tiny numbers they're hard to read.

Those reasons do not excuse you. It is important to monitor your pressures when you are on the road. Low pressure in the duals can cause them to rub and eventually cause a blowout. Low pressure reduces your gas mileage and will cause your expensive tires to wear out prematurely. A low tire will alter your steering control. There are more reasons.

Two actions you can take to resolve this problem of reading the pressures. First, buy and install valve extenders for your inside duals that enable you to read their pressure as easily as your other tires. Second, buy a digital pressure gauge--one with a large face and big numbers--which is not only easier to read but quicker to take the tire pressure. Keep the gauge handy so you can grab it on the way out of the cab to fill up and make it an automatic part of the fueling process.
