Why Tire Rub Now?

I recently purchased the below '72 Swinger. The previous owner had added '71 rally wheels with 245/60R14 BF Goodrich Radial TA rear tires and 205/70R14 fronts

He replaced the suspension with new parts and added a Suregrip rear end.

I've owned it for a month and other than a hot start issue with the Eddy 4 barrel, this car has been a dream come true.

Last night however we were cruising and I made various right turns and three times the right rear tire rubbed on the fender.

They're three turns I've made dozens of times since purchasing and have never had a problem. Why now?

There's about .50 clearance on each fender and like I said have never had a problem before.

I'm worried (I'm a worry wart LOL).

Anything I should have checked or was it just the way it is and I need to be careful?

Was anyone in the car with you?

I'd check the rear suspension, bushings, and axle mounting to be sure its all sound and tight. 245/60/14 is a fat tire by nature of the large sidewall having some flex is another possibility.
 
NICE RIDE..............may want to check the leaf spring to axle u-bolts and insure they are tight. if the PO had the entire rear replaced, after driving sometime you are supposed to re torque those bolts. other than that excess body roll ??
 
I have the same width tire on my Dart. My rear tires would rub when I entered a tight turn driving a little faster than the speed limit. When I added a 1 1/8" Hellwig front sway bar, it quit rubbing.

Extra passengers in the back could be a problem also.

Nice looking Dart...
 
did the sidewalls rub or was it the tread up top of the wheel well? there is a kickout up there that can hit the tire.. maybe the springs settled or you have just a little more weight in the car and that was the difference. it does look to sit real low in the rear.
 
Wow, that is a great looking car! Wonder if your front shocks are still good? I suppose they are new? Also remember hot summer temperatures increase tire pressures and I also think the heat affects all the front end components to some extent.
 
Gotta check everything as already mentioned, could be a lot of things causing the rub. But if the rear springs were changed recently and the last owner didn't do a ton of driving the springs may be settling in, and the slightly lower ride height is causing the rub. Something to consider if everything checks out ok otherwise.
 
Check every fastener from leaf spring hanger, front and rear, to leaf spring bushing, to axle u bolts, and checking the axle retainer bolts would not hurt either.

If not already installed, consider the poly leaf spring bushing set WITH SPACER or shouldered stud, to limit lateral deflection.

Good

I had a problem like that. I put a brand new set of super stock springs on a 68 and within 3 years they had zero arch left in them. I replaced them with a new set of heavy duty springs and gained about a inch and three quarters of height. Then I took the SS springs to a spring shop had had the re arched and added a leaf and put them on another car and fixed it's tire rub problem.
