My Corolla is inflated to 40psi from the recommended 30. When the car was delivered, it had 20psi in them. The first couple tanks, off the top of my head, were 33-34 MPG. I'd have to refer to my Excel worksheet for a more precise number. When I inflated to 30psi, MPG's rose to 34-35 and now with 40psi, I average about 35-37 consistently. My driving is about 90/10 highway/city, I set the cruise on 60 MPH and I rarely see anything over 60.
How long your tires lasting over inflated, are they getting chopped up and wore in the middle at 10 psi over recommendation. It can't be a smooth and comfortable ride like that. My tires cost to much and I have to change them every two years. I see what happens to tires if you under inflate them, they get all feathered, when over inflated they get all chopped up in the middle and wear bad. Not sure if that would help my cause to save gas and spend on a new set of tires for little bit of improvement in gas mileage. But it works for you and that's cool.

At 60 MPH, the RPM settle in at about 2200.

This is a company vehicle that I use for person reasons as well. I pay for gas, the company pays for maintenance (ie. Oil Changes and TIRES). If I were paying for tires, my Michelin X-Radials would stay at 30 PSI for longevity. The 10 extra PSI is slightly noticeable in terms of feel, but not bad.

Than I fully understand your reason. Thanks for clarifying.
