    Im going to be swapping in my ff 14bolt soon and converting my 6 lug front to 8 lug so im going to need new rims. Im just going to get black steel ones cause theyre cheap and i dont have to worry about scratching or denting them. My question is i want to run 38x12.50x15 what backspacing should i get with a 15x10 8 lug rim? Also any opinions on which brand of rim i should go for? All the input would be most helpful

    well do you want the front to be wider than the rear (like it is now) or widen the rear out to be even? i would do the same back spacing all around that way one spare is all you need. some peeps like the wider look on the rear end but its not for me. i would go 4.25 its what i did and it looks bad a$$. look at my rig in members rides www.highboyz.com see if you like it? also us wheel makes a steel white wagon spoke wheel for around 28 bucks. sand it up prim it spray it voila a black steel rim for cheap.

    it is a 10 bolt but i did the 8 lug conversion... and i have only snapped 2 axle shafts do to my own stupidity. it is awesome though as long as you dont ram the snot out of huge boulders and wheel with some sence it will never break.

    brands: I really like Eaton HD steel rims. I got mine from national tire and wheel. Mine are 2.5" of backspacing, but I think you can get them in whatever BS you want. Personally, I think 3.5" or so would be best... if you ever get a dana 60, the less bs you have the less you will have to grind on your calipers if u have 15" rims. Personally, I already had to grind because my street rims have 4.25" of bs, so bs on my off-road rims wasnt as much of a concern. Im not a guru on the subject but other ck5'ers have said that low BS rims can cause more wear on various parts...bearings and such. These same peeps seem to agree that on 1-ton axles, its not a major problem. <shrug> 3.5" would prolly be a good compromise between clearing brake components and the whole part-wear issue. Just my opinion...

    I'd go with 4". That's about as much as you can run before you start getting mighty close to your center link ends. The less backspacing you have the more bumpsteer. Also, the less backspacing you've got the more wear on balljoints and wheel bearings. Ideally, you want the center line of the wheel to be inline with the balljoints.

    If you want your rear tires to stick out as much on the back as the front you can run 1.5" spacers on your 14FF. It's not much of a big deal on a fullfloating axle whereas it's hard on a semifloating axle.

    I just ordered 2.75 bs Pro Comp wheels from 4wpw in 15" 8 lug. Don't have them yet but paid $60 each (chrome). Black is a little cheaper.

    According to 4WPs, the product lines they carry don't make an 8 lug 15" wheel with 3.5" or 3 5/8" BS. It's either 4.25" or 2.75". I just received my 2.75" BS 8 lug Pro Comp wheels. Really wish I could have found some 3.5" BS though. /forums/images/graemlins/frown.gif

    another reason why 4wpw sux. Try rockstomper or national tire/wheel. Either one can hook u up,
