Expert Reviews

Old school mechanical tire pressure gauge, extremely affordable, made in the U.S., built-in deflator valve, reads in both PSI and kPa, pocket clip
Price, durable plated brass construction
If you remember helping out your dad in the garage as a child, you’re probably familiar with the old-fashioned pencil gauge. This tool is a time-tested product that simply uses the tire’s pressure to indicate a reading along the measurement rod. Although this tool might be difficult to read for some users, it’s still one of the most accurate products on the market today. Get to know this classic tool so that it’s a consideration for your toolbox. The primary feature that you’ll notice with this tool is the plated-brass exterior. In fact, it looks silver from a quick glance. Within this tough exterior is a nylon, indicator bar. It has four sides in order to maintain its stability as it moves in and out of the brass housing. The square assembly also gives you an easier time with readings. Be aware that this gauge has a smaller measurement range compared to other products on the market. The Milton model only measures between 5 and 50 PSI. For most tires, this range is ample. You’ll only require larger values for more unusual applications. Purchasing a different tool might be necessary in those cases.

What reviewers didn't like

Red printing on indicator bar wears/smears easily, isn’t as accurate as other gauges
Nothing fancy, very basic tire pressure gauge
