Bedlam, you make a good point about the fields vs roads. But the main point of my advise is that the wheel is not going to break if it is used at, or ever slightly above its rating, unless it is defective. I'm not advocating overloading. The original poster says he is running very close to the limit. Maybe I'm mis-reading, but I take that to mean that he is still under. As an analogy, I don't know about you, but I don't drive 53 in a 55 zone to make sure I don't get a ticket. I go 58, because I know there is a margin of error built into the cops mind. But he says he a worrier, I don't suppose I can change that.
