what size under my 68 dart???

[twotone68]

O.K., I'm sure this is one of those questions. i just bought a set of 15x7 weld wheels from a member They have a 4 1/2 in. back space. I want to put BFG radial t/a's on these wheels under the back of my 68 dart sedan. I was hoping a 255/60r15 would fit without any fender mods or spring relocation?? All answers ,replies,and pics will be greatly appreciated !! As always ,thank you every one for all your help!!rayer:

I'm running 245 60R15 BFG's on 7" W 4.5" BS wheels on the back of my '69 Dart. No rubbing issues at all.
