I've been telling people that for about 2 years now. Last set of tires I bought for my old trailer had documentation that clearly stated that. They are rated to their max weight carrying capacity at max pressure at 65 mph. If you have tires that are rated higher than you need, you can increase tire pressure and run them faster, at the expense of that higher weight rating.
When I bought my tires, load range D were about $10 a tire more than load range C. I overbought my tires just to be safe. I could have over inflated and safely driven faster than 65, in accordance with manufacturer recommendations.
