31's on 5" of BS

Here is the deal, I didn't check out the BS on my wheels when I got them a month ago. Mounted them and 3 of the 4 are at 4" BS (what I wanted) but one is at 5. The local "performance" shop got in one with different BS. I had them mounted then noticed it. They won't do a thing for me now that it is mounted. So my question was. Have you guys ever ran a 31/10.5 AT on 5" of BS. If so any rubbing or problems? I was thinkning of just keeping it for my full size spare, since I was gonna buy a matching one anyways. I haven't noticed any problems for the past two months on 235's other than one sticking in an inch and looking dumb.

Yeah.. I know this is about the dumbest question ever... but bear with me.. I don't feel like throwing out a perfectly good wheel!

I keep a 32 x 10.5 on a OEM 5.25" spaced rim. Like you said it would work as a spare. Too bad the people who mounted it for are beening so particular about getting you the right wheel.

Is it a 15x7 or 15x8? Only asking because the OEM's are of course 15x7.

15x8 I am @ 3.5"s

Where did they mount it to, the rear is where I would be concerned, it gets kinda tight with the wider tires. I know for a fact that the 15x7's will fit, but not sure about 15x8.

It is on the back now. The 31's are being put on after work today.
