will they fit

[Red Cricket]

G morning all, This will go on a 65 coronet with stock equip. seller says 80"s (2) 275/60/15...8" cop wheels and (2) 235/70/15....8" cop wheels. I found these for sale. I may need to inquire about backspace. Unless all cop wheels are the same. Tks for your time !

If they're originally 8" with the slots - not widened or re-barreled - those are SuperCoupe wheels (Volare/Aspen) and worth some money.
Cop wheels were narrower, 7" IIRC. Backspace is typically 4.5" on 8s and 4.25" on 7s, measured inside the bead.
My only early-B Mopar steelie fitments are on '63 & '64 wagons; 7s w 255/70s had plenty of room but 8s with 285/70s (photo) were tight, and that was after I'd narrowed the rearend a bit.

The slotted Police wheels were 7" wide with provision for hub caps. The optional slotted wheels on ' 78-'79 Dodge Magnum were 8" wide with no provision for hub caps.

Topside is right on the money. You can get aftermarket 8in cops with a 4 1/2 BS from Summit. Wheel Vintiques IIRC have a set on my 68 R/R.

he is asking 500 with 95% cooper cobra tires. yes there slotted and provisions for dog dish cap. wheels are 8" wide. Is 8" to wide up front for my car with the above tires??

 

[topside]

Typical fender interference on pretty much all Mopars 62-up is at the bottom front corner of the wheel opening.
Usually a 1" cut at a 45-degree angle solves that.
Widest fronts I've run on an early B were 6 x15s, and the disc brake conversion pushes the track width a bit wider than original drums.
On a 68-up, a 265/50 on 8x15 had plenty of clearance, though.

I would inquire as to how he is measuring the wheels. Bead seat to bead seat , or out side edge to outside edge ??
Makes a lot of difference !!!

^^^ Yup - and I've seen wheel places use both.
I was taught a LONG time ago to use the bead seating area.
Another consideration for filling the wheel wells is of course the sidewall bulge, which changes a bit with rim width.
