Perfectly even tread wear and 5% loss of tread depth after 24,000 miles. That's at 44 PSI, the rated max pressure. Measured to the thousandth inch with a dial caliper.
Same for another set of new tires (both sets bought new) on a different car.
Running my Altima factory tires at the same pressure.
Tires last a lot longer (less heat buildup and stress on the sidewalls).
Lower cost per mile due to longer tire life.
Significant increase in fuel mileage.
After 60k miles of running higher pressures I will never go back, and I drove over 600k using manufacturers recommended pressures over the last 45 years. Worked in the auto repair industry from 18 until 50 and ran my own shop the last 15 years.
