will 275/60/15 fit 71 Duster ?

I am running a 275/60/15 M/T Drag Radial. Slight rub if you turn into a parking lot too fast but other than that just normal bumps are no biggy. I run a 15x8 with 3.5" back spacing and the car does have S/S springs with 3" relocation kit. I love the look of this tire!
