Damnitman, even the 325's are giving me fits on fitting.. might have to drop down to a 315/40-18
I don't want to go to a real low pro tire like a 315/30-18

What if I told you that a 315/30-18 and a 305/30-19 have the same sidewall height?

You have 14.5" You need .75" to the inside and .25" on the outside assuming you are running some type of link suspension. Those are your minimum clearance numbers. You can run the outside tight as most 67/68 camaros don't travel enough to actually tuck into the fender much anyways.

So your maximum section width is 13.5"

325/30-19 is 13" wide on a 11.5.....put it on a 12 and you get 13.25"ish.

I'm running the Ridetech triangulated 4 link & coil overs, mini tubs, rolled lips. if .75 and .25 are good clearances then the 325's might just work.
I don't like the low profile of the 315/30-18 or the 305/30-19
I do appreciate your input, Thank you
