Yet another wheel question

[sandawgk5]

I ordered my wheels from summit the typical white wagon wheel 8X6.5 bolt pattern 15X8 size. The ones I ordered said they were 3.75 backspacing. Well they arrived today and all of the boxes say they are 4.25 backspacing, am I screwed. I have a dana 60 and 14FF and will be running 37 MTRs. Also does a 3.75 backspaced us wheel exist or is it a typo. Just wondering if I need to send these back or just make them work. And I dont care how much I am gonna grind so save the horror stories (that might change after I finish grinding though I will let you know).

Thanks

The only two backspacings I've seen in 15" 8 lug non-beadlock wheels are 4.25" and 2.75". However, that certainly doesn't mean other don't exist, I've never bought wheels from Summit.

Unless you're hellbent on the backspacing I don't think it'd be worth sending them back. I run 4.25" of backspacing and the first side took me about 3 hours, the second to one or one and a half.

So with 4.25 there is no clearance issues with tierods or anything?

Nope, the only wheels I've heard of getting into high steer arms are hummers that haven't been recentered but they run something like 7" of backspacing.

I dont have high steer. I thought that I read somewhere that 4.25 puts the bead on the tie rod ends on the knuckles maybe I misread if 4.25 works I will go with it. Do you have any problems with tires getting into the steering box?

Only been out on a serious run with it once so far, but didn't have any trouble with the tires getting into the box...and that's even with my hydro assist fittings sticking out a ways.

The backspacing I run puts components very near the factory tie rod mounts, but it's not close enough to be concerned about.

I bought these same rims, didn't even occur to me to read the box. It really does say 4.25" backspacing. Oh well, I only have 3/4 ton stuff, less than 30 minutes grinding a side.
