While new rims with correct backspacing is the IDEAL solution, quality adapters are just as good. BEWARE the distinction between adapters and spacers. Spacers like these are illegal in many places:
BAD SPACERS These spacers are bad because of issues with limiting thread engagement and causing studs/lugs to fail and wheels to come flying off at freeway speeds, frequently killing people.
Running a set of spidertrax adapters myself. I love them, and really like the added width (when I first added them after lift the jeep felt MUCH more stable on the street, not so much like it was tottering around on stilts anymore).
I combined them with my lift to run the wheel size I am.
Without the adapters my tires would rub a lot more than they currently do (just a tiny bit on the corners now).
Mine came with a small tube threadlocker, and the only other major concern is making sure you have a torque wrench to check and re-check all your lugnuts.
Following mfr recommendations, I pulled my tires off after the first couple hundred miles and checked torque on the adapters, then reinstall tires, drive a couple hundred more miles, and check your lug nuts torque again. It sounds like a bigger pain than it is, after the first check on the adapters, I just threw my torque wrench in the jeep and drove around with it in there for a few days and a post it on my dash reminding me of the mileage I needed to check at.
As long as you keep an eye on things and dont simply throw them on and forget about them, you should be fine.
