33 psi cold, the pressure will vary with air temperature as well as tire temperature due to driving.
The recommended PSI is to achieve the rated longevity and maintain the wear pattern so it wears evenly across the width of the tire. Any more or less will effect the wear pattern. The feedback on the suspension and steering will be slightly affected as well. More PSI is generally accepted if you load the vehicle or tow a trailer. More PSI will also decrease rolling resistance which might increase mpg depending how you drive. In the end the recommended PSI is to maximize tire life. Adjustment is up to the driver as long as it's within an acceptable range to maintain the warranty and safety requirements. Best not to exceed the cold pressure by more than 3-4 lbs. The PSI will increase naturally when the ambient temperature increases and direct sun heats the road surface.
