Rim and tire fit ment
 

I looked and could not find quite what i needed for an answer. I want to run 15x8s all around with 4in backspaceing with 265/75s all around. This is on stock ride hight c15. Can i do this with no problum? I have factory disc up fount if that makes a difference

Take a straight edge and lay it diagonally across the inboard flange of the wheel. Take a tape measure and measure the distance from where the straight edge contacts the inboard flange to the hub mounting pad of the wheel. This measurement is backspace.

To determine caliper clearance.

A. Caliper Overhang Distance
Used to determine if wheel dish is adequate (in some cases a spacer is required for clearance)
B. Diameter of Hub Center
Required if wheels are hub centric
C. Wheel Stud Diameter
Required along with bolt circle
D. Height of Hub Center
E. Length of Lug and Thread Type (Fine or Coarse)
Required to determine if longer studs are necessary
F. Distance from CL of Hub to Caliper
Used with A to determine if a spacer is required for proper fitment
G. Width of Caliper
Used with F to determine if wheel ID is adequate to clear rotor/caliper package
H. Diameter of Hub Mounting Face
Used to determine if hub is adequate to support wheel/spacer

Ours has 265/75/15's. They work just fine 15x8 Rally. Ours is 68 has drum all around though. Have an 88 blazer 6 hole rally. Same wheel with disc on front. They are factory from that year but work fine also.
