32pitch tamiya is a little smaller then reguler 32pitch
tamiyas 48pitch is a little bigger then reguler 48pitch.
has something to do with it being from japan
I think they're actually metric pitch which is why they never match imperial sizes like 32, 48 and 64. I just don't know what exactly, but I know that .4 pitch (metric) as used in TA05 cars for instance is very close to .64 (imperial) pitch. Some people even mix pinions and spurs of the two (not my choice) albeit it doesn't work at any spur/pinion radius (i.e. the larger the spur/pinion the better the mesh of the two pitch gears). At smaller radius (smaller numebr of teeth) the mesh is quite rough and ultimately impossible, because curvature becomes too different.
