The main purpose of the tag is to take some of the weight that would otherwise be on your main rear axle, allowing a higher GVWR for the coach. Compared to a non-tag coach, one with a tag will generally be able to run a lower pressure in the rear tires, since they carry less weight.
The answer to your question, though, is that when you weigh your coach you get 6 weights instead of 4, then set your tire pressures according to the tire manufacturer's chart, just like everybody else.
