Ok, standard 235/75 R15's are equivalent (near as dammit) to a 29x9.50 R15, but becuase tyres vary from manufacturer to manufacturer, some measure bigger than others.
What I'll say about the Kumho AT's & the MT's I have now, they are quite a narrow tyre for the measurement, with a rounder profile than some.
Can't say 100% but the likelihood is that they'll fit without problems.
