? Wheel & tire size

[Aarons Air]

I have a 68 coronet. I want to put 15x12 wheels with 50 series tires on the back. Does anyone know/have pics of what fits well ? What tire size ? Wheel back spacing ? Thanks guys

15x12 rims in stock wells?

 

[Aarons Air]

Yes. A 68 -70 dodge b body are about as big as they come.

Do lots of measuring...on my 68 I have 15x8" rims, 4.5" backspace with 275/60 tires...about 1.5-2" max to tires rubbing, when you add the sidewall bulge to 12" of rim I don't think it will fit without modification

15x10 4-7/8" back space. N-50 15" on 1969 Coronet. not sure on the 12". like mentioned above, (MEASURE CAREFULLY)!

Thank you for the insight and link. One thing i wonder about though. They are discussing a plymouth. I think i read somewhere that a 68-70 dodge b body has a bigger or longer wheel well than a 68-70 plymouth b body.i have no clue. Lol.

If I'm not mistaken, coronets actually have smaller wells than other b body's

Is that about as much as you can stuff in there without rubbing ?

Do you have a pic with this set up ?

I would like to use Keystone classics. But the 10 " rim back space is only 4 1/8. I dont know if the extra on the front would clear ?

The easiest way to be sure is to remove a rear tire, hold a 2' level (or a straightedge with a small level against it, whatever you have) against the inside of the outer wheel lip and measure from that line to your leaf spring. (make a drawing it helps!) The distance between that lip and your spring is what you're after but remember the tire will flex and move a bit so you need a little clearance to avoid rubbing.. The inner fenderwell on the outer side has a bulge up in there, but usually won't interfere unless you run a pretty tall tire (like 30" or more)

Thank you. This seems pretty clever. But i hoped someone on here would have already done the measuring/ trying. And could just show a pic. And tell me the numbers.

I do not have a good pic of this set up. I sold the tires now. going to do this again when these tires are gone! I am looking on old computer discs for a pic.
