Lowered tire psi, got better MPG ???

[GasSavers_Scott]

Now this just blew me away, the entire summer I kept my tire pressure at 44. A storm was coming and I lowerd it to the factory 28 psi, on long crusies I really have to work to maintain 29 mpg on my on board computer. I lowered the tire pressure and jumped right to 34 mpg. After a trip to Phillie and back, with 2 hours of downtown driving, I came home with 32.1 mpg registered. This car is an oddity, it has factory low profile 18X10 tires, in the rain with max psi, the car will slide from side to side hydroplaning, in the snow I have to lower it to 25 psi, or it will just spin the tires forever.

The only thing I can think is the factory toe and camber adjustments must lend themselves to more friction with a harder tire. The lower pressure may throw off the friction point and thust lower rolling resistance. With the lower pressure I can feel the wheel is heavier in parking lots, it does stick to the road better in turns, the lower pressure makes the tires feel sticky.

But I got to tell you it was easy to keep it at 32-34 mpg at crusie and after city driving in Phillie brought me down to 28 mpg, I P&G'd it and it walked right back into the 30's. Wow!
