315 or 325 tires on early a?

Without Mini Tubbing, will I be able to fit 275-60 tires under my Valiant knowing that I will have to move the springs in to the subframe rails?
Apologies for the Hi-jack.........

you will have to move the springs an mini tub it before you can fit anything bigger than a 255 under it,

jayson, how wide is your rear end? im running a 275 60 15 with a 15x10 wheel with 5in back spacing, it doesnt rub but its close. i moved my wheel tubs flush with the frame and my springs centered in the fram rail, how wide of a tire will it fit without rubbing (car will not be street drivin
