People just don't care and nearly nobody out there knows how dangerous it is to run a tire with too low on air pressure. It heats the tire up and can eventually lead to a blowout. My buddy owns a tire shop and he sees it all the time with guys putting on big LT AT tires to replace the smaller P rated tires on their trucks. They keep the same psi (usually 35) when the tire now needs about 47 psi. Eventually the belts go bad or worse they have a blowout.
