Bias Ply tire options for 1969 Camaro

[Survivor 69/Z28]

So I took it out for a drive on some very bumpy and somewhat dippy roads with two little girls in the backseat and my wife in the passenger seat plus a full tank of gas. I also cut the wheel all the way to left and right while driving in tight circles in a parking lot.
I never felt or heard any rubbing but what I did notice was a slight line on the outside of the front left tire. After further investigating it was slightly and I mean slightly touching the top bolt head on the inner fender. The other side didn't touch because that top bolt was not in. I removed the top bolt of the left side and I am almost certain that it fixed it but didn't have time to test it. I am going to buy a few flat button bolts today on the way home from the office and I think I am good to go. Looks wise, I am very pleased.

I think if someone didn't want a wider lower type stance and went with a stock size tire like maybe a 215/70 there would no issues. Plus every car is a bit different as we all know.
