1970 Duster wheels

I am running 295/50R-15 BFG radial T/A's w/ 15X8 with 4.5 back space on the back of my 71 Duster. _ _ _ _ _ View attachment 1715453730 --
-- I was thinking about 15' X 8" wheels with 295/50-15" tires, but I was concerned about the extra width of the tire beads vs, the width of the wheel. It looks like quite a bulge. Do You think that it's safe ? -- This is for My 64 Falcon Sprint with mini tubs, and the springs moved in.
