I know that some do it, but no way I would be able to get a 275 tire in the stock wheel wells of my 67 Coronet 500. I have M/T ET Sreet Radials P255/60/R15 tires on there now with a 7 inch rim with 4 1/4 rear spacing. I don't like them, but they fit. www.summitracing.com/parts/crr-3975712p/overview/I had 8 inch rims with 4 1/2 inch spacing, but when I went around corners the tire would rub the wheel well molding - I really liked that rim. Someday I will shorten my rear to make these rims fit. http://www.summitracing.com/parts/wvi-63-5812042/overview/
67 Coronet 500 9.610 @ 139.20 mph
67 Coronet 500 (street car) 14.82 @ 94 mph
69 GTX (clone) - build in progress......

Been down this road.....
I agree, not sure how some people on here get anything larger than a 255 on the rear. Maybe 70 VS 60 series?? After dealing with my 67 I would almost call people out ( not saying I am) on installing any larger wheels or tires without shackles "lifting" the rear up. Again this was my experience.... I did use my original rear springs after rebuilding them, wanting a "lower" look..So perhaps my car rides an inch or two lower than stock, being that the springs have "settled' some...
I spent hours measuring, remeasuring, using straight edges, looking at wheel well taper, tire width ( not tread width) space to the leaf springs etc, as I did not want $700 of wheels that did not fit...
Fronts are a no brainer, its the rear qtrs on 66-67 that are extra small. I used the Chrome center/polished alum rim TT's .. Found they offered quite a few backspace options, you might call them or just check with Summit ( where I purchased mine)....
I have 7" front w/ a 4" backspace ( 3 3/4" std?) would work fine though.. 8" on the rear with a 5 1/4" back space.. 5 or 5 1/8" might work better on the rear.. with 245-60 tires.. Was going to go with 255 but just did not want ANY rubbing at all.. Still had to install an 1/8" wheel spacer on one side..
Biggest problem on 66-67 cars is the upper part of the rear wheel well tapers together getting smaller as you go up ..

I wasn't going to answer because I don't want to be responsible if it doesn't fit, but a Plymouth wheel well should accept a 10.7 inch section width tire (most 275s) on an 8 inch rim with 4.75-5 inches of backspacing. I currently have a 10.7 inch section width tire on a 7 inch rim with 4 inches of backspacing. I'd recomment another 1/4 to 1/2 inch of BS to make it safer/easier. Its a little tight on the drivers side because with my ride height the wheel lip is at the maxium section width of the tire, I may need to lower my rear end a bit or trim the wheel lip (1/4 inch of clearance currently) but will see. My understanding is that the Dodges have a little bit more room. Look at the SECTION width of the tire though, not the actual size. It varies.

275's on an 8" Rim would not even be close on my car. I run 255's on 7" rims, and they're tight! My street setup is 245's on 8" rims, they're even tighter. 275's on 8" rims...... Not a chance.

Maybie Dodge is different but 8" with 5.25" backspacing and a 275 60 15 fits fine on mine
As I said above NO WAY on mine..
Was thinking though, how many of us have the original rear end?? 68 and newer increased the width by 3/4"?? Could be a HUGE difference when comparing.. I know my rear brakes were not correct ( 10" ) when restoring my car, which makes me think the whole rear could have been changed as I never have measured it??? And back in the "day" we used to change these out ALOT??? Just a thought...

Yeah, they do, more so on the inside. You can fit more inside if you jack it up high. I have 4 inches of BS so I'm on the outside edge with tons of room on the inner wheel well. 5 1/4 is the other extreme. Is seems most available wheels have too much or not enough BS for these cars. IMO 4 3/4 on an 8 inch rim is ideal.
