So this is all interesting, back in the day I had a Chevrolet 1500 with the 5.3L engine.... on which I ran C Range Tires that where inflated to around 50 PSI.... several friends has similar trucks that used just regular LT passenger tires that they kept around 40 PSI.....
Long story short I was achieving 1-2 more MPG.... and I was the more aggressive throttle happy driver.......
With all that said, proper inflation is important.... but so is ride comfort my friends trucks will a bit more of a comforting ride.... at 50 PSI my 1500 rode more like a 2500.......
There are trade offs....
Now I have a 2500, and have found that I needed to back the air pressure down 5 PSI, to get a more comfortable ride, when not loaded. This truck runs E Range tires and when not loaded are at 60 PSI..... don't have anything to compare to at the moment, but I think the gas millage is pretty good at around 13 MPG......what I can't wait to see is how this new 2500 pulls my camper here in a couple of weeks....
