Although most drivers know Accutire MS-4751WC, many still do not take preventative action by regularly checking their tire pressure. According to a survey by the National Highway Transportation Safety Administration (NHTSA), 27 percent of the passenger cars and 33 percent of the light trucks (including SUVs, vans and pickups) on America’s roads have at least one substantially under-inflated tire.

Under-inflation of tires increases the likelihood of many different types of crashes, including those involving: (1) skidding and/or loss of control of the vehicle; (2) hydroplaning; (3) increases in stopping distance; (4) flat tires and blow-outs, and (5) overloading of the vehicle.

For the small amount of time it takes, checking tire inflation at least once a month is one of the best investments you can make to get the maximum life out of your tires. Proper inflation can also improve gas mileage by more than 3% when maintained regularly. Keep this in mind: Under-inflated tires can lower gas mileage by 0.4 percent for every 1 PSI (pounds per square inch) drop in pressure of all four tires. You may want to check your tires more often during the winter months. Tires will lose about 1 PSI of pressure for every 10 degrees Fahrenheit of temperature drop.

Keep an accurate tire pressure gauge in your car’s glove box (many gauges at “air stations” give false pressure readings) and check the tire pressure when the tires are cold. Never trust the appearance of a tire as a gauge for inflation. A tire could be 10 PSI low on pressure and not appear to be low on air. Use the recommended inflation pressure listed in your vehicle’s owner’s manual or on the inflation sticker found on the driver’s door jamb. While you’re at it, don’t forget to check the spare. There’s nothing more annoying than a flat spare when you have a flat tire

Tire pressure checking is an important auto safety check that everyone should do frequently. Use the Accutire MS-4751WC to get quick, accurate readings.

purchased this for my Mom as part of a car safety kit that I put together for her and it works just fine. Upon receipt I tested it for accuracy with my older electronic gauge in addition to my manual gauge and it’s very accurate. It has a good grip and the angled design allows the thumb to place adequate pressure behind the gauge screen to get a good seal and an accurate reading. I will grant that it’s been 6-7 months since the unit was purchased, so this review does not take into consideration the product’s battery life other than to say that it’s still working after 6-7 months. If the thing dies and I consider it to be premature then I’ll return and add to this review.

However, the most enjoyable aspect of this product has been reading some of the reviews. As previous reviewers have pointed out, some of our fellow reviewers failed to remove the sticker with the 28.5 reading and mistakenly thought the product was broken. The value of this gift went up considerably with the amount of laughs we got with giving it and using it. Of course I stuck the 28.5 sticker back on the screen to see if my Mom would notice when I insisted she test it in our driveway. Thankfully she did.

Several reviewers mentioned the difficulty getting the gauge to seal well because of the absence of a rubber o-ring (and several of those bought o-rings from a hardware store to remedy this problem). Others mentioned that Accutire has now started to make these gauges with factory-installed o-rings. I was glad to receive mine with this apparently important modification. Nevertheless, when I tried it on my first tire, I didn’t get the angle right immediately, so quite a bit of air escaped. It took the simplest of adjustments to fix this problem. I USED TWO HANDS. By doing so, I could minimize wiggling to the right or left and could easily apply enough force to seal it up right away. It’s not necessary to go into contortions to see the reading while applying the gauge because, within a few seconds, it beeps to let you know an accurate reading has been obtained. It continues to display the reading for about ten seconds after removing the gauge from the tire. I didn’t really miss the absence of an air release valve, since I found it was easy to purposely over-inflate each tire a bit and then let the air out in 0.5 increments by just holding the gauge at a slight angle. Very precise. This gauge is the easiest to use of any I’ve ever had. I hope it has a long life.
