Re tire inflation and rotation: I have a family member who manages a Firestone dealership, has been in the business for 20 years. His guidance for my cars has proven right consistently over time. In our case, and I speak only for us, running the tire at 40 PSI has worked. Wear is better than average for the mileage, fuel economy is good (consistently better than manuf. ratings), and handling is solid. Rotation has also helped keep wear down. In the past I have had other tires I did not maintain this way, and they wore out faster.
With the rough road conditions in the Northeast, tires just wear faster at lower inflation in our experience.
