LOL, no, it doesn't, as the tread is fully in contact with the ground.
It CAN round the bottom of the tread contour if too high a psi is used, but that can happen on a wide rime too, etc...but a narrower rim is more sensitive to it.
In short, its a perfectly reasonable solution.

According to BFG, the measured section width decreases by approximately .2" for every 0.5" rim width under the specified size. BFG A/T 33x12.5x15 measures 12.4" on a 10" wheel. Therefore there is about an inch less section width with a 7.5" wheel under best conditions. Over-inflate a little and it would be worse.
Just observing. Not making a judgment on how good it is.

I had some 7 inch rims with 12.5 tyres and it was a rough ride and tyre wandered all over the road. When I fitted the 8 inch rims to the same tyres it made huge difference smooth ride and tyres stopped wondering. In Australia is illegal to fit 12.5 wide tyre to a 7 inch rims plus you would have no insurance if you had an accident.

People have been running 35's and 33's on stock rims for ages on this forum..its perfectly fine, in fact its better than having steelies. The stock alloys are cool imo..i lke em..

and the mazda b-4000 (or ford ranger) tend to wear the tire inside very fast
the front got serious camber when you load the truck
and a like to take the corner a bit fast , that dosen't hlep too

Just a cpl of things for those with a similar setup..., you do need spacers on the stock rims coz they rub on the trackbar at full turn with the discos disconnected....Also, there are a cpl rubber stops on the tailgate to keep the spare more secure...these need to be trimmed by 1 cm so the 33 can fit on the tailgate...heres a quick pic i took on my phone...doesnt do them justice really...they look shit hot!

To correct center wear
Based on the research I’ve done about putting wider tires on Merrill wheels is that the tire pressure will have to be adjusted from 30 to 35 street PSI down to whatever it takes to flatten out the tread. So most likely you’re either a have to attach a GoPro camera to look at your tire tread or have someone follow you and look at your tread to find what psi flattens out the bottom of your tire
