Unless the tires are almost flat already, it takes some doin' to pinch-flat 40mm+ tires. Most people overinflate big tires.
Like JAG, I've had nothing but good results with the calculator/Frank Berto method. As a concession to real-world riding conditions, though, I choose the 45%/55% numbers regardless of whatever my actual weight distribution is, and round up, never down.
