2014 Tacoma Prerunner 4cyl- Rims Question

I just bought a used Tacoma (it's my third). The dude is the original owner and seems like a stand up fella. Everything he said checked out on Car Fax and he has a vehicle check from Toyota from a couple of weeks ago. Anyway, the truck is in good shape save for some scratches but I just can't get past these rims (pictures attached). He said these were from the manufacturer but I've never seen them on a Toyota before, and they suck!
1) Has anyone seen these on a Tacoma before?
2) Is it possible that he is lying to me for nefarious reasons?

The tires are P245/75 R16 Yokohamas. I am looking at Rims from 2003-2007 4Runner- 5 Spoke, 6 lug pattern. OEM 17.5 X 7.5

I get confused about what sizes matter with Rims versus tires and I imagine that the installer can switch out the TPMS sensors and put them on with different rims?
