67 section width and clearance

I have read many posts but most are on wheel back spacing.The only thing about tire clearance is about the tire rubbing on something.
I used TA 265/50x15's (10.8 sec. width) in the 70's, but they are no longer available, and they used to rub on something.
Have a 67 that has 11 1/4" between inner fenderwell and inner lip on outer fenderwell. I have read that some have used 275's with a sec. width of 11", but even with rolling the outer wheelwell lip 1/2" this would only allow a tire to wheelwell clearance of 3/8", give or take.
I am not trying to imply that an 11" sec. width would not fit but that the clearance is not sufficient.
A 255 with a sec. width of 10.2" would give a clearance of 3/4", give or take. This sounds to me to be more reasonable for driving on the street.
Or am I wrong, if so , what say you?

Am inquiring about the rear fenderwells.

Re: 67 section width and clearance

I hear ya. I think the key to running 275's in a stock wheel house is having the rear end up with stiff suspension, as they'll surely rub otherwise. Back in the 80's, I ran 275/50's on a 67 with air shocks. Never again.

Presently have 255/60's, 4.5" BS on my 68, 4 leaf stock suspension. Haven't had it on the road yet, but it looks to be awful close to rubbing the fender lip.

I run a 275/40/18 on my rear with no issues. No mini tub, no fender rolling. Hotchkis 1.5" drop leafs w/Bilstein shocks.

275/60/15's and never an issue...now the 285/60/15 SH's were very tight and rubbed the inner fender on hard turns and off-camber bumps.
