My 93 c1500 currently has 15x7 A/R outlaw II wheels with a 3.75” backspace, -6mm offset. Tire size is 235/75/15. I’d like to put on a set of US mag Indys (slots) and I’d like to go to an 8” wheel if possible? I mounted the tire on an 8” wheel just to be sure it would fit and it did, but it was just an old Basset race wheel. They offer a 15x8 with a 4” backspace, -12mm offset. My tires are like new so I’d like to reuse them if possible and then put on on a set of 265/70/15s (after I use up the ones I have) which I believe is the size the 454ss came with. I believe they were also a 7” wheel tho? Is anyone running 15x8s on a 2wd with a 4” backspace and if so is there any clearance issues? Truck currently has stock suspension.
