Exactly What Wheels & Tires Fit C Bodies?

Was talking with another c-body owner. He has 215-70R15 tires on his 1973 Polara, which are 27 inches tall.
I think they are too short because they are 27 inch tire height and c-bodies are 28 inch stock tire height.
Before I say anything, would any of the G78 or H78 OEM tires be 27 inch tire height?

traveling, so going by memory. a 215/70 could (IMO) look "squatty" and "skinny (depending on wheel width)" on a fusie/later C.

"smallest" 70 i'd do on that vintage C is a 225/70.. that tire is a little over 27" diameter i think. so in a G78/15 - probably pretty close in diameter to a 225/70 -- 27.5" maybe?

Aside: any "pre -metric" vintage (e.g., first letter alpha-numeric) tire is too old for my tastes. been EOP for decades.

any G,H, J, & L 78 works on a fusie/later C, though L's are diameter of today's light truck tires.

me? i like 27~29" diameter metrics on C's post 1968. 225 & 235/70-75's fill out wheel well and usually allow an 8-inch wide wheel with no interference issues.

page 2 of this thread shows equivalent, overall tire diameters with various wheel diameters -- many options so you can at least avoid messing with speedo if non-OE diameter is used.

LSS, G78, or H78, with 6-7 inch wide wheels, and backspacing ~4 inches (again, IMO caution with age of such a tire) could look ok. Not for me (due to age of tire), but it would be better than a 215 anything and a fusie/later C, IMHO.

hope others with access to more data can chime in.

1966 Monaco

Seller reports: "17x7 Chrome U.S. Mags Rambler wheels, running 235/45R17 tires."

No backspacing provided but looks to be around 3.5 to 4.0 inches, judging by stated wheel width and placement in wheel wells.

17x9 rear with 275/55/17. 5" backspace (0 offset)). 17x8 front with 255/55/17 4" backspace (+12mm offset). I had a little rubbing on the drivers rear because the diff is not centered. I had to trim the valuable SS wheel trim and pinch welds about 1/2"

were the fronts Special Order to get that offset? I'm considering this exact setup on my 69 Fury III Vert...
