Tire Fit Question

[CTENG in KS]

Gonna order a set of tires in about an hour or so, but I have backspacing issues.  '85 runner, extensive fender trimming, buying 35-14.5-15 boggers, What is the largest backspacing I can run without clipping the springs?
I know the 2.5 rockcrawlers would probably do it, will 3 inch backspacing work...anyone with wider tires pls help!
Thanks!

3 inch would get you in the ballpark but they would still rub a little

[Skinny_Pedal]

would 3 3/4 backspace work? thats a pretty common backspace i thought

[WHITE_TRASH]

yes it is a very common backspacing.  The black wheels from my rig at Goldendale were 3 3/4" and they rubbed with 35's.  If I had the ifs hub spaw done then they would not have touched as they would have effectively been about a 1" backspace.

so the greater the backspacing...the worst it is?

I'm running 3 3/4" back spacing  on my 84 runner with stock rear axle and no spacers. I have allpro springs in the rear and the 36X12.5 rub on the frame. Oh ya 5" springs

Ya LILSWAMPER...Smaller backspacing shoves the tires out farther = increased trackwidth for stability and keeps the tires off of the springs.  Drawback-Johnny Law gets to see more of your tread. 

I went with the 2.5 inch rackcrawlers...geez though, they are getting a little pricy with the steel prices the way they are...

Hopefully within two weeks I'll get some pictures of the tires on the truck...Going 0 lift so the sawzall has been getting some excersise!

Oh ok thanks...whats the post a tire can pop out?

It depends on where you live...CT says no tire sticking out past the fenders and at least 50% rear coverage with mudflaps.  I plan on rigging up some removable mudflaps for road driving that can be tossed in the back on the trail.  I don't know what I'm going to do aboout the fenders though???  Maybe some creative body work??
