Which spacers did you use?
I wheeled the crap out of >spidertrax< with stock rubi wheels & 35" mud grapplers for almost 3 years
This whole argument has gone down a dozen times or more on here.
Most of the the "spacers suck!, they'll kill you and rape your cat!" people have never used them, just heard stories.
I'm sure a few have failed, but so has at least a few of EVERY part.
I'm only gonna stand up for spidertrax, since they seemed to be the best, thats what I went with.
They're hubcentric, so most of the load is carried on the wheel hub.
People dont freak out and worry about their lug nuts possibly coming loose but thats the big "fear" with spacers. Theyre held on the same as your wheels.
Worrying about spacers coming loose is the same as worrying about your wheels coming loose and falling off.
Actually, your wheel lugs are MORE likely to back off, since you're supposed to use loctite on spacers, but no one loctites their lugs!
Mine were on since day fucking 2 of ownership up until I got my recentered humvee wheels a little while back. 3 years+ and 50k+ miles - most of it with 35"s.
I used loctite when I put them on never looked back.
Now they're on another JKO members rig, still doing their job.
The spacer horror stories /stigma mainly stems from the old crappy spacer plates from the go fast section at the local autoparts store that go over your lug bolts and behind the wheel.
They negate any hubcentric support the wheels had, put extra shear strain on lug bolts, etc.
And then idiots started stacking them, radically increasing the leverage on the lug bolts and reducing the amount of threads holding everything on and shit would break and fall off. - "Why did Fred's wheel fall off when he hit that speed bump?" "He had spacers and they made it break"
As far as extra leverage on hubs/bearings - its the same whether you have 6.25" backspace rims (stock) with a 1.5" spacer or a 4.75" BS wheel. The tire contact patch is going to be the same distance away from the centerline of the bearing surface.
