This may surprise you but for that size tire (roughly a 33"), and with your 4-speed automatic, you want 4.88. Yes, 4.88. The 4-speed automatic has such a steep overdrive ratio, .69, that it reduces the highway rpms too much. I.E. it makes the highway rpms too low.. With that size tire, the engine would lug most of the time with 4.56 and would lug all the time with 4.10. With the 5-speed, 4.56 would be appropriate & with the 6-speed, 4.10 or 4.56 would be appropriate. But with your 4-speed 42RLE automatic transmission, don't even think about 4.10 or 4.56. 4.88 is ideal & will NOT produce excessive highway RPMs.
To give you a little more insight... my last TJ was stolen so I bought a used replacement with 4.88 gears, 35" tires, and the same 4-speed automatic you have. That 4.88 isn't enough gear for its 35" tires, it really needs 5.13 or better 5.38. The engine lugs with 35" tires and 4.88. But that same 4.88 would be ideal for your slightly smaller 33" tires.
