Info on 33's for my stock TJ

My family and I are moving to Montana in a few months thus I will need to upgrade my tires anyway and figured while I'm at it I should put in the money for the tires I want in the end anyway.
I currently have 235/70r15. I believe, via online, that is a 29" tire.
I have to verify but I think I have 15x7 wheels.
I see a lot about 33x10.5 or x12.5 etc... That mixed with the confusing numbers of offset and backspacing I'm getting lost. lol

I would like to get 33" tires and keep the 15" wheels, hopefully without any other mods to the jeep to fit them. Is this possible?
If so what do I need in the way of tire width?

If I can't then what else do I need to modify to fit 33's on my Jeep?

Advanced appreciation for patience, I'm new to the Jeep scene and am getting really confused with all the Tire numbers and conversions I'm finding in the other threads.

It can get really confusing for sure. First off, what wheels do you have on your TJ? If they are steel, then they are 15x7, and most aluminum wheels are 15x8. So as far as the tires go, I would do the 33x10.5's to minimize tire rub on the control arms when you turn. Second you are going to have to put a lift on your jeep. I would look at a 2in spacer lift.

I run 31's x 10.5 General Grabbers on stock aluminum wheels on a stock 4cyl 2001 TJ. I get a little rub on full turn sometimes depending on speed and weight distribution.

TO move up to 33" I will need to do a 2" spacer lift like my Brother Inlaw has on his 2000.

He is running 33x10.5 . his tires look funny as they seem tall and Narrow, but he has same rims as me. Another friend has 33x12.5 and they look great. You will need a 1.24"+ wheel spacer on stock rims and larger for 12.5 wide tire.

Again, newb here, bear with me.
A spacer lift would be the body lift correct? Lift without extending with bigger springs and shocks?

The 1.24+ spacer for the wheels is referring to the round bit that extends your tire bolts farther away from the wheel well correct?

33x12.5x15" tires on 15x8" wheels with 3.75" backspacing is the perfect balance imo

Backspacing is something that still confuses me. What is that and how is it done.

For the jeep world, we are mainly concerned with backspacing.

It's basically the measurement from the edge of the rim to the mounting surface. So a larger backspace, brings the rim closer inside the wheel well and a smaller backspace will allow the rim to stick out farther.

3.75" - 4" seems to be really common and look good.

Now if you need to use adapters for your wheels, you need to take that extra distance into consideration.

Iíll do some research as Iím still not quite grasping these concepts. The wheel is solid metal so how do you change these factors? Is this all done through adjustments to the wheel and tire or are there other parts needed to achieve these measurements?

You don't change or modify your rim backspacing, it is what it is when it left the factory.

But manufacturers make lots of variations to accommodate many different types of cars/trucks, so buying the right size is key.

Youtube will be your friend in this case, so you can see it visually better.

So in order to change my backspacing I need to buy new wheels?

Simply put, yes. (Adding adapters to fit a wheel with a different lug pattern would essentially add to the backspacing I believe)

What wheels do you have? Are they stock wrangler rims? I'm not sure if you can mount a 12.5" wide tire on a 7" wide rim, I think the cutoff is 8". I could be wrong though.

I believe they are the stock 7Ē rims. But I have to verify that before I can say for sure.

So what's your goal?

Get bigger tires on your existing wheels without any other modifications needed? [If memory serves me well, I believe the best option is 31's if you do not plan on lifting or trimming anything]

or purchase new 15" wheels and 33" tires? [I believe you need at least a 2" lift and you would want to look for wheels that come in your lug pattern (5x4.5") with 3.75"-4.0" backspace].

I want a good all around tire that will give more ability in light-medium trails as well as not being destructive to my road driving. Also aesthetics. Iím cool with lifting the Jeep I just canít afford a big budget lift and tires. Currently Iím trying the asses what I would need to accomplish this and then I can find out how much money is needed to make it happen.
One day I want a rock crawler but for now I think a small bump in lift and tire size would give me everything I want while I learn the skills needed to use my Jeep like itís supposed to be used.

No worries, we all were there at first. I'm just trying not to further confuse you.

Search the biggest tire you can fit on a stock TJ and I'm sure you will find all kinds of useful information. I don't know much about the different types of small budget lifts so I can't really help there. I know it's all over this site though if you search.

A popular all-around (aggressive looking) A/T tire is the BF Goodrich KO2, but there are plenty of other good tires out there others prefer.

Alright so on YouTube I have seen a couple of videos where they use spacers on the wheel. Spacers will give you more negative backspacing to clear the steering/suspension components. To adjust the offset you would look at different wheels. I think I got it now.

Hey, feel free to check out my pics. Just installed an RC 3.25 inch lift on my 02 TJ. I bought the Jeep with aftermarket rims already installed (very modestly priced rims), a very common rim for Jeep's-D shaped steel wheels. The previous owner was running those wheels without lift (stock springs / shocks) and 31 X 10.5 tires. I wanted 33's (X 12.5's) eventually on these same rims so I bought the smallest and cheapest lift that got me to 33X12.5's. I paid around $550 for my lift including Springs, upgraded Nitrogen Shocks, and a new nitrogen Steering Stabilizer. I am completely happy with the results and will be shopping for tires soon. I have no current plans to crawl or trail ride...having a Jeep has been a longtime wish that I am just getting around to realize. I've had my Jeep about 2 months. I've bought aftermarket (used) Rampage seats and just ordered a new carpet kit. Bedliner will go down before the carpet and seats. As I said, my pics show my Jeep in stock height and after the lift, with the same wheels and tires. Feel free to ask me anything else you need. I'm no expert but I'm a quick learner. Thanks, Jim.

You will need more clearance to fit 33" tires regardless of if you have the correct backspacing. 33" tires need 4" of lift if you plan to off-road.

You might be better off with a 32" tire and a small body lift 1", or budget boost. I suggest this because you mentioned budget.

Spacer Lift is a large bushing that goes on top of the Coil to give you 1-3" of lift. Without having to replace all the suspension. you will need longer shocks and a possible a Transfer case drop kit. you can get them in packages for a few hundred dollars. cheapest lift and keeps stock ride.

Wheel spacer goes behind your wheel to increases the distance out the Wheel sits from the rotor and gives you a wider stance. This helps stop the inner tire from Rubbing on suspension with larger tires. or you by new wheels with a bigger offset, which does the same thing.

Best explanation of BS/Offset I have ever seen! Thanks.
