The cavalier attitude about exceeding "max sidewall" pressure is astounding. Teams of engineers at major tire manufacturers have worked with teams of engineers at auto makers to determine the maximum safe tire pressure - but we know better because someone on the Internet pumped his tires 30 PSI over the design specification of the tire. Clearly, a few of us put saving a few bucks on fuel ahead of the risk to ourselves, our families, and others on road. This isn't only about risking a blowout, or premature tire wear, it's about the affect that over-inflation has to driving dynamics, and the car's reduced ability to maneuver (or stop) in an emergency situation.
I'll admit that I have raised pressure in my tires 6 PSI over the door sticker's recommended 36 PSI (which has improved FE), but I won't go anywhere near the stated maximum 51 PSI sidewall pressure. I'll put my trust in the engineering team that designed the tire over an anonymous Internet user's "research".
