I determined the tire pressure was high due to the tire's max pressure being rated at 70 PSI and I pumped to 50 front 60 rear, that's 70% and 85% of max rated pressure. The tires were providing little to no suspension and wasn't getting very much traction in the small gravel on the hard packed dirt. I could have stopped and let air out until I got a more subtle ride and/or better traction but from there I'd have no way or accurately correlating that feel to an actual pressure value........but with a pressure gauge I would be able to establish an accurate and repeatable pressure value once I did reach the feel I wanted.
