Interestly enough, Michigan State Police recommends Tahoe pressure to be set at 44PSI.
I will say that running higher pressures will aid in better fuel economy because of less rolling resistance but also less contact patch. Some hypermilers (ie treehuggers) recommend as much as 90 psi.
Science agrees, safety board probably not so much...
