Rim Fitting Question

[MBOffroading]

Ok, I've recently picked up a new set of tires, and now I'm looking at rims.

Ive decided on these - Pro Comp Rims
15 x 8
3.75 backspacing
6 on 5.5

Question is will this work on a stock '74 FJ40 with drums all around? Currently I have 16" rims, with something like 6" backspacing, and 2" spacers (PO did this), I know without the spacers, I hit the steering TRE.

Would like to know if what I listed up top will work with what I want.

As you probably know, 3.5" backspacing is stock. I ran 15x8 spokers with 3.5" backspacing with no problems. I don't know if .25" is a big deal or not. maybe someone with more knowhow than me will chime in. Worst case you may need 1/4" spacer which is no big deal. Most decent tire shops will mount up your wheel and tire combo to check for proper fit. After all, they want to make the sale. good luck.

Ive got the exact same wheel setup with 33x12.5. Unfortunately I cannot answer your question for sure since I have not put them on yet. Should be by end of next week, I can let you know how it goes then. I was planning on running a 1/4" spacer as I believe I read somewhere that 3.75 will rub on the tie rod

Thanks for the info. eyebms, looking forward to hearing how your setup went. I'll be buying the rims at some point in the near future, already have the tires.

Did these ever work out for you guys?

 

[MBOffroading]

Actually yeah. Here is a pic of mine,

15" Pro Comp rim
3.75 backspacing
8" wide
33" x 12.5 tire.

Work great and no issues with rubbing.

33x12.5 on a 15x8 with 3" offset. No rubbing issues.

I realize I am responding to a pretty old posting and you may not be on Mud anymore but if you are...
Are you running any lift kits or extended shackles on your rig in this pic? Thanks!

I want to run American Racing Mojaves that have 4.5" backspacing. Since stock is 3.5", I assume I will need to run 3/4-1" spacers?

The thinner the better, I have a 80 or later full floater axle in the back and discs in the front.

SSCR Are you talking about these? http://www.summitracing.com/parts/are-39815883/overview/
They are available with a 3.75" back spacing which may work without any spacer at all. I run 15 x 8 black spokes (I forget the brand but maybe American Racing) with 3.75 B/S and no spacers on my '76. I shaved a millimeter or so off my calipers but didn't really need to,
