This....SMB's are like the old saying about motorhomes. If you need to know how many mpg's it gets you don't need to own it.

And, your mileage really isn't going to increase no matter what you do but you are beating yourself up running that kind of tire pressure. About 55-60 front and rear will greatly improve handling and especially comfort. Some run even less. That answer from SMB makes no sense but most manufacturers and fleets recommend it.
There are lots of threads here on tire pressure. Check em out.
