Question about tire pressure
I'm currently running give or take 36 psi in my pirelli run flats. My question is does more psi in the tires affect the gas mileage and performance in a negative way the more air that is in the tires? How is tire wear affected with 33-35psi VS. say 38-40psi? Is the car more likely to perform better with acceleration with 33-35psi because more rubber is on the ground?
