Tire Pressures For 2500 QCSB
I recently purchased a 2005 Ram 2500 Quad Cab Short Bed 4x4 with the Hemi. After my first fill up, I was averaging 16 mpg, which I understand is very good for this truck especially given that it has the 4.10 gears. However, after checking the tire pressure and finding that each tire was different, I adjusted each tire to the recommended light load pressure as per the sticker on the driver's side door (Rear: 45 PSI, Front: 60 PSI). However, after doing so, I found that my ride felt overly soft and bouncy, and that my gas mileage had dropped to 13 mpg. This leads me to believe that these "recommended" pressures are not, in fact, the best pressures for my truck.
What are you guys out there with similar trucks running for tire pressures?
BTW: My tires are the stock size, LT 265/70R/17, and Load Range E (Max Inflation 80 PSI as per the sidewall of the tire). Thanks in advance!

I've had 7 full size trucks in my life and I've ignored the door sticker on every one of them. My rule of thumb has always been to run the tire at 80% of the max cold tire pressure listed on the side of the tire. I've had great longevity on my tires as a rule and seem to get about optimum fuel economy.
Run them "E" load tires at about 65 PSI...
