Not to worry Dave. Obama, the candidate of "change," will claim that properly inflated tires will last longer, thereby avoiding the needless "overflowing" of our nation's landfills. Tenchusatsu

David, I got around to reading that whole article. Surprisingly, keeping the A/C on doesn't waste much more gas than keeping the windows open. And using cruise control saves much more gas than one would expect. Of course, slowing down and not driving with a heavy foot saves the most gas. Tenchusatsu

"Cold Hard Facts: No measurable effect on the vehicles we tested" Interestingly enough, that seems to have changed. From a later, bit more comprehensive test. Tire Pressure and Fuel Economy Most people pay little attention to the tire pressure in their cars. How far below specification are the typical car tires? And how much gas does this waste? We decided to see what driving on tires underinflated by 25 percent below spec would do to fuel economy. We chose 25 percent because this is when the tire pressure warning light illuminates. We recorded fuel economy while driving with tires 25 percent underinflated and the cruise control set at 65 mph. We then compared the data to driving at the same speed with tires inflated to spec, and found these results. Lexus ES 350: 4.6 percent loss in fuel economy if tires were 25 percent underinflated, from 32.5 mpg with tires inflated to spec to 31.1 mpg with underinflated tires. Toyota Tundra: 2.9 percent loss in fuel economy if tires were 25 percent underinflated, from 20.8 mpg with tires inflated to spec to 20.3 mpg with underinflated tires. edmunds.com
