After some reading I went up to sidewall 44 psi. Instant ticket to 48 mpg. Slowing down and adding a few more techniques, block heater, and grille blocks and now I'm just shy of 60 mpg and hoping to break it by summers end.
So little story moral is higher pressure is a good thing. As long as your not going over the limit. Granted you drive a sporty car where lower pressure might be desirable but if your talking about fuel economy then upping the tires is a must.

Not trying to be argumentative or anything like that, but increasing pressure that much is VERY dangerous. Not only is there more of a chance of your tire blowing if you hit a pothole or drive over railroads, or something like that, but in addition, air expands as it heats up (which happens when you drive), therefore, if you check your psi when its cold, and its at 44, for example, it will expand (even though its in a closed container, a tire expands to accommodate the expanding air), thus making it even more prone to damage. While you do get better mileage because of the reduced friction, it might not be worth it for safety reasons.
But obviously, that decision is up to you!
Sorry for thread jack... so yea... how bout them K&N intakes...
