Nitto 275 60r15 measurements?

The tires you’re asking about are close but do fit. I can’t say how far off of the wheel lip they are. The car isn’t close to me. The wheels are old Cragars with something like (I really don’t remember the exact depth but….) 3-5/8, IIRC.
Oh! The rear is an 8-1/4, FWIW. 72BluNblu would know the off sets and axle widths for sure. (He’s my go to guy!)

Your rear tires are very close to the leaf spring.
