Op is 100% right however, there are some trucks/brands that ride absolutely terrible with full tire inflation when not carrying or towing and people will underinflate to make the ride even bearable. Thus sacrificing handling characteristics, ability, safety, and of course tire tread life. I have to ask why would they even do this when there are better choices and so avoidable? Some vehicles even ride harsh and jolting when loaded! They'd made their choice and get the ride that comes with it and then use the band aid approach to solve the well known issues that are built it. DUH!
