Biggest tire on Stock 67-69 Dart

And they fit! I just installed 245/60/15 and 215/65/15 Cooper Cobra GTs around 15x7 Wheel Vintiques steelies with 4.25" BS on my 1967 Dart, stock 8 3/4 axle and spring location, Mopar SS leafsprings, stock wheel wells and lips. 255's would possibly fit, but it would be super tight on mine. Plus as explained previously in this thread by others, every car is different and may or may not fit what someone elses will, so measure and order conservatively. If you still have room and they don't rub when driving, then maybe maximize size next time you order tires. Mine don't rub under light driving with a light load, I haven't carried a heavy load or cornered hard yet.

Looking at your pictures I have an acre more room on my 68 GTS than you do. I took a measurement yesterday and between the inside sidewall of my 235/70/15's to the SS springs I have over 1 inch of clearance. Between the rim and the springs I have two inches of clearance. I'm using a 15X7 rim with 4.25 backspacing, my new rims are 15x8's with 4.75 backspacing so I should be good
