MT 275/60/15 ET Radials

I am building a 1972 Demon. I have a dana 60 for it, stock width with disc brakes, leaf springs in stock location and staying there, mopar XHD springs and caltracs.

Will the 275/60/15 MT ET radial fit on the car or am I going to have to get the 235/60/15?

This is my first A body to build, I normally do B body mopars.

Looking at weld prostars 15x4 on the front and I think a 15x8 on the back.

Just looking for som insight on the MT tires and what works on the Demons.

Have a A and A transmission for it with a 3800 converter, 4.10's in the dana and a crossrammed 426 hemi for power, TTI headers and 3 inch exhaust.

275/60/15 will fit if you pay careful attention to the back spacing and/or offset, The tire will be real close to the front of the fender as it's a 28" tall tire. The next smaller size is 255/60/15 I like this 27" tall size to because it's a little shorter but still fills up the fenders good. Base on my A body experience I would think a 3.75" to 4" backspacing with a 8" wheel would work on your stock suspension Demon but you should always measure, and make sure you do both sides as there is a difference up to 1/2" in some cases.

8" wheel is a good choice
