Quick question here I researched a little and didn't find a specefic answer to my question. I recently bought some 15x8, 8 spoke rims which measured 3.5" from the inside lip to the outer edge on the inside, So I suppose this is my backspacing. With the 1.5" BJ spacers and 33x12.5 tires will they rub on the UCA. Thanks. Btw im trying out the newer goodyear wrangler duratrac tire I can't wait!
