I’ve decided to go with the Maxxix Bighorns in size 26" (they run big) on my 2015 Rubicon. I am totally confused on matching tires with rims and could really use some help and explanation.

Here’s what I want and the numbers:

ITP SS112 wheel size options:
12×7
14×6
14×8

Maxxis Bighorn 26" tire rim size options:
12×9.5/12×7
14×7/14×7
15×7/15×8

If I wanted to go beyond the stock 12" size wheels…say…to the 14"….what size tire should I go with? I’m confused with what combos will work together. Would the 14×7 Bighorns work best with the ITP 14×8 or 14×6??

I’m guessing since there is no 15" ITP wheel option the 15" Bighorns are a no go?
