Looks like 15'' rallye wheels to me. Was it born that way? I' m asking because, usually, an E body with 15'' rallye wheels should have a space saver tire in the trunk, at least in 70 and 71. I' m just telling you this because you asked us if we see something wrong, but you can keep it like that too. A space saver wheel/tire with the tire inflator can & bracket will cost around $1000.00, maybe more... I will put a 14'' rallye as a spare in mine. Space savors are too expensive for me...
