Load bearing is a MINIMUM spec. It must carry your truck’s weight. I’m not talking about excessive, just the minimum.
And those people, and I’m one, are correct. You completely missed the point. The cheap tire you buy today, may be a useless, unsafe, rock-hard lump of carbon in 2 or 3 years and you’d never know it.
And yet they aren’t. But obviously nothing will allow you to understand the risk you put others in by continuing to drive on unsafe tires.
