Goodyear says check your tire pressure, it's cold out
Keeping your vehicle's tires inflated to the correct pressure is one of the simplest ways to make sure you're not wasting fuel unnecessarily as you drive. Most drivers know this, even if they don't take the time to actually check the PSI in their tires every week or two (and which is the better tire gauge, from a green perspective: the old fashioned stick that doesn't use batteries but isn't entirely precise or a new digital pressure reader that does require batteries and gives you your PSI to the third decimal point?). So it's not exactly news to tell you, dear reader, to get make sure your tires are properly inflated. But, as Goodyear notes in a media advisory yesterday, this is a cold time of year for most of North America, and lower temperatures can cause tire pressure to drop by a pound or two for every ten degrees the mercury drops outside. This was just a reminder. And now back to your regularly scheduled posts.

A no-brainer. The one that doesn't eat batteries.
Tire pressure needs only to be kept within a pound or two of the correct pressure. More precision will not be noticed in gas mileage. From a safety standpoint, the tires on each end of the same axle need to be within about 1 pound (repeatability).

Inaccurate stick or digital ? The answer is neither. The best tire gauges are analog dial.

Your comment regarding the "PSI to the third decimal point" reminds me of a great Chemistry professor I had and his animosity toward digital displays. His concern is they convey a false sense of accuracy. A NIST certified pressure gauge that really is accurate to 0.1 psi costs around $500.

There is yet another type of tire pressure gauge that is liquid filled from QuickCar that cater to the racing car segment and is supposed to be accurate.
Nonetheless, the primary issue is still about being consistent in keeping the tire pressure at the correct level on a regular basis.
And it is certainly important to pay extra attention when there are drastic changes in the ambient temperature, such as the winter months.
