‘67 GTX, P275-60-15s, will they fit poll.

I'd test a 1/4" spacer. Of course that will mess up wheel stud length. Perfect wheel for the car.

The Torque Thrust wheels use shank lug nuts I bought extra long ones thinking I might need to use spacers. I’ll cut them to the length needed for full thread engagement.

keep in mind how much thread engagement you have at the hex. no hex engagement will probably cause the shank to fail.

It actually has no thread engagement now. The studs are flush with the wheel.

On my 70 Road Runner, I have 275/60R15s on the rear and 245/60R15s on the front. All rims are 8" rims with 4 1/2" backspacing.

We tried them on my buddies 67 GTX to test fit. After some wiggling and trouble, we were able to get the 275s on the car, but they likely would have rubbed around any corner or bump. The 245s seemed to fit much better.

He ended up getting 245/60R15s on 7 inch rims. Here is a picture. The car is still undergoing restoration so no driving experience yet.

Take a chance on breaking the shanks away from the hex.

I ran 275 60 -15s for years
on an 8 inch 4.5" backspace
I loved the way they filled out the wheel well
but they rubbed every time I hit a bump
I got tired of of the pucker factor with each bump
I went to 255 60 15s and no more rubbing
Close to the same tread width and the drag radials hook really nice

275/60 15s

255/60 R15

I’m going to try and fit P275-60r 15 BFG TAs on my 67 GTX in the next couple of days. I don’t know if they’ll fit, but I think maybe.

In your response, presume I have the perfect, or nearly perfect offset/back spacing. That’s the goal anyways.

I was thinking of putting skinnier tires on my "67 RT but I don't think they make any.

I ran 275 60 15 on this coronet, with 7 inch C body road wheels. Only modification wasView attachment 1978305 I swapped in slightly longer shock absorbers which might have let the axle hang a little lower. The 275's made a 318 car look like it was packing at least a 383.
My red belvedere got longer shocks as well. No other modification. It's running 11x3 drums on the back.

15x7 c-body road wheels should have 4.25” backspace. What is the distance from inside tire bulge to leaf spring? Or does it rub the inner tub first?

What backspace was on the 15x7’s on your Belvedere to fit 275/60/15 tires?

I know the question is not to me. But this might get you close to your answer.

This is with my MT ET Street Rs P255 60-15. They measure like a P265 60-15. They are 27.5" dia., 10.3" cross section width, and 8.8" tread width. On a my 7" wide rims with a 4.25" back spacing I have exactly 1" clearance from the leaf spring.

The BFG P275 60-15 measures 10.9" wide. The math says that the BFG P275 will have a 0.7" clearance to the leaf spring with a 7' rim with a 4.25" BS.
