That's not a picture, it's an exaggerated illustration. This is just an example of the propaganda the auto manufacturers and tire companies put out to get you to feel you haven't left your living room couch driving down the road and to sell more rubber by having you wear your tires out quicker.
Here is a realworld example, my left front tire with nearly 22K:
The sidewalls on my tires bulge more with less air than with more. Those illustrations are a bunch of hooey. That or they are from the days of bias-ply tires. The steel belts on modern tires don't allow the tire to bulge in the center of the tread. Judging by the track left on my garage floor when my tires are wet they lay down a full tread pattern.
My experience has been very good with 60#, sun, rain, snow and ice. I have more resistance to hydroplaning, better handling, cooler running at high speeds, more even and longer wear, and to top it off lower rolling resistance and thus better gas mileage.
And more realworld experience, (save the we're not driving fully loaded police car arguments, much of this applies to any car): Driving Under Pressure (full article) - CleanMPG Forums
