They were lighter for the same strength and easier to cast.

Later batches of the VR K class (e.g. K183 built 1943, K190 built 1946). 
Wheelsets were often swapped around in the workshops and I have seen
photos of Ks and Ns with both types.

VR started to build bits for the R class at Newport as early as 1941, but
the war got in the way and North British eventially built them with SCOA-P
wheels. A2.986 has 6' "poxy" driving wheels which were made for an R.
