> The only time you should stray from the OEM recommend pressures is when you change tire size.

To each his own, but be aware that the Technical Editor of Road & Track diasgrees:

"Typically the vehicle manufacturer’s pressure recommendations are biased a bit more toward ride than tire longevity or what most enthusiasts enjoy. More spirited driving often calls for slightly higher tire pressures. As you found out, this makes for more responsive steering and a firmer ride. Go too high and the ride deteriorates, the tire’s contact patch is reduced and traction suffers.

On automobile tires, the maximum inflation figure molded into the tire’s sidewall is the maximum safe cold tire pressure. You obviously should not exceed it, and many times you won’t even want to come close to it due to ride and handling concerns. It’s simply the highest tire pressure the tire can physically withstand, not a recommended inflation pressure."
