Thanks DCH! Great new topic to start. I have renamed it to "Tire gauges" so that we can discuss anything about tire gauges in this discussion topic, including your posts As mentioned, I look forward to reading the rest of your research!     Drew Host Vans, SUVs, and Aftermarket & Accessories message boards
#3 of 71 Accuracy of gauges by tronsr1 Jun 28, 2001 (2:42 am)
I just received a digital tire guage for a birhtday present {it was purchased at Radio Shack} and I am anxious to get your digital read-out results. I keep 29 lbs. in my 2001 Ford Escape {as per recommended on the door} and find the digital guage very easy to use and also very easy to "read'.
#4 of 71 Digital Gauges by dchopp Jun 28, 2001 (5:40 pm)
The digital gauges I tested where very accurate over the range, however I found two that where off by as much as 4lbs. at 35 lbs. the owners brought in the directions and it required a self calibration check prior to using. After we did it the accuracy improved to about a 1.5 lbs. So read your directions and see if it requires a self calibration prior to using. DCH

O.K. Will check directions as per above post. Thanks for the input.
#6 of 71 Digital Recommendations? by cooldude1755 Jun 29, 2001 (4:24 pm)
Does anybody have any good recommendations for brands/models of digital gauges? How about info on price and accuracy?
#8 of 71 Recommended Tire Gauge by sirfile Jun 29, 2001 (5:02 pm)
Accutire makes an excellent digital gauge that is easy to use and has a large readout in .5 pound increments from 5-99 pounds. The gauge is recommended by The Tire Rack, and through www.HerringtonCatalog.com for $29.95. I also saw it advertised at Sears today, for only $13.95. It makes a great gift for others [or for yourself]. Be sure to check your tires once a week when the tires are cold.
#9 of 71 Tire Gauge Accuracy Part 2 by dchopp Jul 02, 2001 (12:57 pm)
Tire Gauge Accuracy Part 2. In Part 1, we did an evaluation of the cheaper pocket or pen type gauges. Part 2 consist of the more expensive heavy-duty double-headed type of gauge. Price range is in the $5.50 to $13.00 range. Basically the same names as indicated in Part 1 and a few new ones like ACCU. Most were purchased at local retail and automotive stores such as Napa ,Advance etc. We also tested some Analog or dial type of a gauge. Since these gauges cost more, we expected more from them and they didn't disappoint us. Since these gauges have a much larger range than the cheaper pocket type, we had to expand our testing to the 100lb. range. These gauges were tested at 25,35,45, (lower range) 60, 75, and 90 lb. range, which we called the upper range. Some where brand new, some where old like over 10 years. The gauges with the metal type indicators read about 1 to 2lbs long over the short range and about 1 lb. long on the higher range. Long means that for a known source of air pressure 35lbs. these gauges were indicating 36 or 37 lbs. Exercising the indicators did nothing to improve the accuracy. As these gauges start to get old (6 years and above) they tend to get a little sloppy on the higher end indicating as much as 3 to 5 lbs. higher. The shorter range still remained accurate within 2lbs. The newer type replaces the metal indicator with that of a white plastic dial much like the cheaper pen or pocket type. Easier to read I guess. These type of gauges read differently over the ranges, much like the cheaper ones. On the short range these gauges indicated about 1 to 2lbs. short. So for 35lbs. they would indicate 33 to 34 lbs. On the upper range they were very inconsistent with some reading 1 lb. short while others reading 1 to 2 lbs long, while down in the lower range they were all short. Exercising the indicators a few times improved some in the upper range but not in the lower range. Still overall the accuracy over both ranges was very good. The analog or meter type of gauges were very inconsistent but accurate. Some were short while some were long over the ranges and the brand didn't seam to matter. Two identical read differently. The 8 we tested were within 2 lbs in both the lower and upper ranges. Just remember to check to make sure the gauge reads zero before checking air pressure. Most come with an adjusting screw to do this. I dropped one on the floor and it indicated about 3lbs long. When in the first test, it indicated 1lb short over the ranges. After I zeroed the meter, it was ok. One analog type was reading all over the place as much as 8 lbs off. Here the meter had a static charge on the meter face. I rubbed a little Wd-40 on the meter face and it was ok after that. The results show once again you get what you pay for. These types of meters showed pretty good accuracy over the ranges and age didn't seem to slow them down on the lower range. Part 3 which consist of Digital Gauges will follow soon. One tested so accurate, I went out and bought one and tested it for repeatability and it indicated the same as the first. Which one was it? Stay tuned Until then---by DCH

Keep up the good work. Your posts are very informative.I am still using my digital guage from Radio Shack and eagerly awaiting the results of your tests.

Your research is impressive. Looking forward to your next report.
