No reputable installer should be doing that. They will go with tire manufacturer's recommended/required wheel specs, and in the case of pretty much all branded 37x12.5's is about an inch too narrow at 7.5 to be safe. Can you do it" Sure. But when you pop a bead rounding a corner a little aggressively don't say you weren't warned.It is fine to run on stock 7.5 rim
Can’t argue with specs. Safest thing is to get new rims that have appropriate width and backspacing.No reputable installer should be doing that.

If the rim is too narrow for the tire, it causes the tire have more lateral movement than it was designed for. Not safe. If the rim is too narrow for the tire, it causes it to "bow" or bulge outward, weakening the sidewall.
Doesn’t Toyo make the ATIII in 35x11.5x17 that is specced for 7.5” wheels?Not really safe (most places won't install either.) If you look at the specs for 37" by 12.5" tires from the usual players (BFGoodrich, Toyo, Cooper, Nitto, Goodyear, etc) they all have minimum wheel width as 8.5. Heck, in my experience, I wouldn't personally go narrower than 9" for 37's.
The stock rims could go with 35x11.5's - but I think Nitto is the only one really making a decent tire at that size.
It drives 100 times better than my supercharged JK on 37s. I’m so used to passing cars at full throttle with my JK that when I pass now I routinely see 97-98 mph…not on purpose. The point is that at that speed it’s still riding really smooth. I did upgrade the stabilizer to a Fox. I don’t recommend weaving in and out of traffic too hard but I do sometimes just because I can. There was a little loss of power I feel on the higher end but not much launching, the pedal commander helps out with that….at least in my mind it does, it absolutely jumps off the line, especially in launch modeHow do you like how it drives and handles with the 37's?
Stock 392 wheels are safe up to 40's. They are also headlock capable wheels. Here is my 392 on 37's with AEV 17x8.5 and I love them, these spent 3 years on my JK until we bought the 392.Has anyone found a wheel that is a close aesthetic match to the stock rims but is at least 8.5" wide? I like the look, but want 37s!
Depends on how you hard you drive it. I had my 2013 front axle sleeved and gussetted for running 37's. Never had a problem with stock axle shafts or u joints. Have heard reports of people bending axles with 37's but have never seen it in person. Some say that on road maneuvers can stress axles just as much (hitting potholes at speed going around a curve).We're putting Anthem 17x9s on ours and looking to get 37" GENERALS. There's a concern raised on whether the axles need to be upgraded to handle it for off-roading. Any thoughts?
