Furthermore, tire load weights are very conservatively rated.
I would imagine that the rating comes when fully loaded, the tire can still handle extreme conditions. Without an extreme condition, it likely can handle a heck of a lot more. I have seen many a pickup load that without doubt exceeds the weight limit of the tire, yet holds fine..... but just try to hit that deep pothole.
