Absolutely true in the literal sense. And, for someone shopping for bargain tires, the chart could be useful. But, if you look at all summer high performance tires in the OE sizes, you will find that all significantly exceed both the real world load rating and speed capability of the car. One would have to run at speed for a considerable distance on significantly underinflated tires to experience a pressure-related problem. But, you can never be too careful where safety is concerned. For example, my favorite bourbon comes with a cork, not a screw cap, lest I could cut myself in the process of operation. We all have our risk tolerance.
