Keep in mind back spacing most greatly helps with the width of tires not the diameter. I have 34x9.5s on stock bs Alloys, but if I had some 15x8s with stock bs and 34x12.5s it wouldn't work more than likely. The diameter of both tires is 34", but its the width that makes the difference.

For that matter 10.5" wide tires will fit with stock back spacing on stock rims. With the wider rims any back spacing 4" and below should be more than enough. 3.75" will more than plenty with enough room to run 12.5s later on.
