7.50 x 16 should work out to 31" exactly. If you get desperate finding one you don't actually need 16" tyre/rim if only a spare... as long as outside diameter is the same...
There is some strange things with tyre sizing, as said before most tyres are smaller than they say, with the exception of like simex.
But even within simex 32x9.5x16's measure bigger than 32x9.5x15's and 32x10.5x16 measure different to 32x10.5x15 which measure differently to the 9.5's so within simex they all say their 32's but their all different diameters... (admitting not all that different but still)
Think it was a 32x9.5x15 but there's been a single super swamper tyre (from memory) on trademe for past few months for a reasonable price... can't spot it now but may get relisted at some stage...
