Do I need more than 1.75 inch spacers on front suspension for 22s on 33 tires?
I have a 2014 Jeep Wrangler Sport 4 Door. Do I need more than 1.75 inch spacers on the front suspension to put 22s on 33s? Also, do you thinks its mandatory that I regear after upgrades like this? My gear ratio now is 3.73. I plan to put the TIS wheels 544b -44 offset 12 inch width. The tires Im going with a 33/12.50/22. Also, this is my daily driver and have plans to drive it from Oregon to Ga and back. Just over 3,000 miles. I dont really plan to do any off roading. Maybe light trails.

22 is the center of the tire, the big hole in the middle. It has nothing to do with how much lift, if any, you need to run a 33" tire, or how much backspacing you will need for any given tire.
Yes, a small spacer lift will be fine for a 33x12.50.
If I did the math right, those 12" wide rims have a backspace of around 4.75". Does that sound correct? Stock backspace is around 6.25". Most places suggest around 4.50" for 35x12.50's, so that should be ok - though I have no experience that wide of a rim. But, why do you want 12" wide rims? (then again, I suppose that question could be asked about choosing 22" rims also... ) Anyway, check the specs for the specific tire you want, it will list a 'recommended rim width range'. Just a guess, but it will probably top out around 11" wide or so. (meaning the tire manufacturer will probably indicate that 12" wide rims are too wide for that tire...) So just as a heads-up if you run into this, make sure your tire shop will actually mount that tire on rims that are outside of the mfg's recommended range.
Regear? nah. Drive it and see what you think, but with that engine/gear combo you should be fine.

22's don't belong on a jeep, much less with a 33" tire. Good grief.

Everybody has an opinion, but it's your jeep, I believe that other than looking odd, you lose a lot of traction when you take away sidewall height. the smaller the rim diameter and the larger the tire diameter you have much more sidewall flexibility that gives you better traction.
but running 22's you loose that flex and
everybody knows right off that the only off road is when it pulls into a parking lot at the mall or driveway.
But then again, that's my opinion and it's your jeep

Sir, IMO after 500 miles on the trip you will understand why this is NOT Done, except in LA or Miami where as said; the only off road it sees is turning into parking lots from City streets.
