my combo is GM HD 44 front and 60 back with drum brakes
I heard that some BS kills wheel bearings :question:


I have some 15 X 8. 5 lug with 35s BFG M/T BS unknowen

I have to go to 8 lug but not sure what BS I should get so I dont fawk somthing up


also should I get a 10" winde rim

:(

caugh

youll be fine with 3.5 BS with that set up! jiMMy

USE THE SEARCH BUTTON!!!!!!!!!!

ok thanks


just did not want to be changing wheel bearings all the time

Current thinking in the local circles indicates one should try to push the backspacing in as close to the wheel rim center as possable.
This is supposed to do two things ...
First of all, putting the rim center closer to the WMS and the two bearing's middle point on the spindle is bound to be easier on your bearings because it helps lessen the side load.
But most importantly, and with crawling in mind, if your tire is along side of a big rock a centered back spaced rim will pivot better at the rock and a shallow backspaced rim will want to push the rock.

what vehicle is it on? if its not a fullsize I would feel safe pretty much any BS and stay with 8" rims, they'll work better.

I think if you go to heavy axles under a lighter rig, you can afford to play with backspacing without killing bearings.
Let's face it, the axle was designed to support a heavier rig and heavy loads. ;)

On a huge truck carrying full load B.S. would matter for wheel bearings but that shouldn't be a major concern here.

THe main concern is steering geometry. Center point steering is much better than steering with a lot of scrub radius. More backspacing puts a moment on you steering axis which makes it harder to turn and easier to break stuff

threr under a scout but is has lost some weight to to the princapuls of rust

3 or 3.5 should be fine. Much farther out than that, and you'll be rough on bearings, but rougher on steering parts if you smack it into a rock. I'd go 3 vs. 3.5 just 'cause of better brake clearance, but that's in part 'cause you didn't say what kind of brakes you've got.
I also agree with NE-Roktoy, unless you're either running beadlocks or a 14"+wide tire. If you're running 15x10 beadlocks with 12.50's that's OK (I'd want to stay narrower though), if you're running 14"+ tire width, go 10's.

What he said.
You have some room there due to the lack of weight from what it was intended for. Lets face it....We will ruin the bearing before they ever go bad. Maybe thats just me.:(

Ford brakes have more clearance problems (bigger calipers) than Chevy or Dodge--but only certain years of Fords have the really big calipers, others aren't so bad.

The Chevy brakes that you appear to have, are pretty much the common ones, with less clearance trouble than Ford stuff. You can probably go 3.5 backspacing without too much trouble.
