tire rub

I have 205/78/15 in the front of my 67 Camaro. I just converted the front brakes to disc. Now my front passenger tire rubs when I turn to the right. It rubs at the rear of the fender, on the inner fender bolt and inner fender.
The drivers side front does not rub.

What are my options
Thanks
Barry

Re: tire rub

Is it anywhere near time for new tires? You will probably have to go with a smaller tire. If it is just rubbing on the bolt you could grind it down a bit, but it may hit worse if you are turning and hitting a bump at the same time. For tire size, did you mean 205/70/15?

Re: tire rub

I just checked out your garage and noticed your car sits pretty high up front which puts the widest part of the tire right at the area where it is rubbing. Maybe another option would be dropping the front an inch or two. You'll have to take a closer look if you think this is an option.

Yes those are 205/78/15, not a typo. Because of the brake upgrade had to get rid of my 14 inch aluminum rim and tires. Those are the tires i used for storage. Was going to buy 15 inch white letter, but trying to find a size that will fit, since the conversion from 14 inch to 15 inch

Re: tire rub

You could use a button head bolt. I would also get a front end alignment.

Re: tire rub

If you post the wheel width and backspace you will find lots of help with selecting a the right tire size. I am running 15X7" wheels, 4.25" backspace, with 225/60/15 tires. No rubs at all.

You can run your tire size HERE

Your current tire is 27.6" in diameter compared to my 25.6". This should explain why you're rubbing.

Not that I know of. You can remove a wheel and check for manufacturer stamps that you may or may not need to decode. I believe most manufacturers stamp/inscribe the size on the back side of the wheel. GM rally wheels are code stamped on the outer rim near the valve stem. You can also confirm backspace while your at it (see photo). I suppose if worse comes to worse, you can hold a straight edge on the inner rim as shown in the photo and one on the outer rim, then run a dowel or rod through the center of the wheel and measure from straight edge to straight edge (if that makes sense). Make sure the straight edge sits only on the rim and not the tire. You can trim a strip of straight cardboard or thin wood to a length of 17" so it doesn't hit the tire. In the photo, the vertical ruler is the backspace measurement (from inner hub to rim edge).

Re: tire rub

I already know the backspacing is 4.25, just need a way to measure thickness of rim with tire on

I don't think GM back years ago planned on having people run things like we do today and the tolerances were a little looser.

I wonder if just through the years if the frame has shifted some or a bushing is worn, or something might be bent ?.

I would maybe get under the car and inspect things and see if anything is out of place.
