Took me a few times to read, but I think what he's saying (RCode, please confirm).
If I bought the 3.25, and drove it with 14", it would be something more than 3.25 (mebbe not 3.89). If I put 15's on, it would be less than 3.25
If, I went with 3.89 and 14's, then I would be more than 3.89, and I put 15's on, I would bring it closer to 3.25 than 3.89...
Did I get that correct RCode, or am I all jacked up. After I typed it, Im not sure anymore!
