I've been looking around but I can't find a good answer as to what rims would fit my Ranger as a full size spare. Apparently not all 16x7 Explorer rims fit since the backspacing can be different depending on the year. I don't want to have to use the 15" stock spare if I'm off-road. Here's a photo of my current rims.

 

Well I lucked out and the local wrecking yard had my exact rim from a 4x4 they got in last week. Set me back $81 with tax.
