New to forum Need Wheel Help
 

I have a 98 EXT. cab 2wd...has the dreaded 14" wheels on it. Getting 30x9.5x15 BFG Ta Ko, I found these on CL, 15x8 I like the look. Seems the bolt pattern is the same, Backspace is 5 as far as I can tell. And after checking the spec, this jeep wheel has a bore hole 71.5
I am going to check them out in a few, so some help would be great, bore hole is mainly what I am worried about. 70.3 ranger/71.5 jeep. Is this going to be a problem??
