I will agree with the definitions there.

I personally would never inflate my tires past the limit posted on the tire. I always assume that the manufacturer has tested these tires to a point that the number on the outside stands for some point at which some of the tested tires began to fail after use. I actually go even beyond that and will adjust my tires based on my driving for the day. I have found that my tires will go up by a factor of 'x' based on what kind of driving I'm doing, more so for highway driving then around town driving, so I keep them at the max listed on the sidewall unless I'm going on the highway where the temperature will cause the 'x' factor of expansion to occur in which case I release pressure enough so that it stays within safe limits while they are heated up.
