Gas Economy Alert: Fall=falling tire pressure

Now that the seemingly up and down summer is over and in some areas, like mine, the sweatshirts and jeans are being broken out and the tanks and shorts are being put away, Fall seems to be in full swing, and with falling temperatures, that leaves the distinct possibility

From the carconnection:

As morning temps dip lower and lower, checking your tires weekly before setting off, which of course you always do, might result in their pressure dropping week by week. Don't worry - if the change is small, you don't have a leak. Rather, as the air in your tires gets colder along with the weather as fall progresses, its volume decreases. This results in it taking less space in your tire, ergo a drop in tire pressure on the gauge. For every 10 degree drop in temperature, tire pressures drop roughly 1-2 psi (depending upon tire size and overall volume of air inside). Because of this same phenomenon, always check tire pressure in the morning before the tire has heated up from driving.

Nice info, huh? Well, with Mr. Barack Obama claiming that tire pressure gauges can ultimately save our gas crisis, it's even more evident now, yes? Seriously, though, one of the biggest things that is taken for granted when it comes to gas economy is checking tire pressure--so with this possibility even for those that are decent about checking, this should give you even more of a reason to be diligent about it. SO DO IT, OK! :)
