Are these going on aftermarket wheels or stock? Stock wheels don't have enough backspacing for 33s. Mine couldn't even be put on the vehicle. What size btw? i run 285 70 r17.
As far as the tire carrier, It will stick out more than the stock tire but a 33 will be fine. I did have to replace the hinges on mine due to previous owner shenanigans, but I just got the upgraded hinges, carrier is still stock. Someday perhaps I'll upgrade it, perhaps
I'm not sure what my jeep had been through before I got it but I keep finding strange things, and you may as well. For instance when I was poking around behind the glove box I discovered the male side of a power plug, cigarette adapter type, still have little idea what it's suppose to power, best guess is that some previous owner had a CB in the jeep. Probably why l had to replace the rear hinges, though it still had stock wheels and tires on it. Hell, my first 'mod' was replacing the entire rear brake system, everything was rusted solid, calipers, rotors, and all.
No, the problem is the width. My 285 70 R17 are a bit thinner than that and they couldn't even be put on the vehicle because they impacted components behind the tire. Spacers would fix this, but like said above, that size tire on the stock wheels will also be an issue, strange wear on expensive tires.
Sorry bud, jeep upgrading can be a bit of a pain, you have started out well by asking here.
