I run the tires on my F-250 at 70 PSI. (sidewall max is 80) It rides like a wagon on dirt roads, but it handles quite well on smooth pavement. Can't tell if it's improved my fuel economy. I only drive it about 3K miles/year.
I've been running the tires on my Mustang @ 50 PSI (sidewall max is 51) for the last 3 months. It hasn't made a significant difference in MPG vs 40 PSI. (less than 0.06 MPG - 0.19% difference; and there was even less difference between 35 and 40 PSI) I'll be setting them at 35 PSI before I go to work Monday morning. A harsh ride isn't worth an improvement of less than 0.1 MPG.
Fuel economy is nice, but sometimes I just gotta put the spurs to my pony!
