Rear tire height clearance 69 dart

I also run 275/60/15 on a 68, had to trim the fender lip a bit, and move the axle back about 1 inch on the springs, but I had some slight inner wheel well rub on hard cornering. Just rub on a smooth surface though, no edges or catching on anything, and was because of width rather than height. I would vote-no problem with a 225 tire.
