But I don not understand why in the math expression below the spacing behind the letters is different.

If you need to have a variable PYR, you should probably do \def\PYR{PY\kern-2ptR} $\PYR$ (modify kerning at your own will; you might also want to use em instead of pt units, or you could use \! if you don't need to be too accurate) The extensive original spacing is most probably related to the fact that in mathematics you usually mean multiplication when you write one letter after the other. In other cases (for example when you have a function like "sin", "cos", "lim", ...) the spacing will look better. Still, the fact that there is such a huge difference between PY and YR looks more like a tiny font bug to me (but it is already present in CM, so LM is unlikely to change it, at least until they switch to OpenType Math).
