How big is too big

I've got a '97 4cyl, all totally stock. 4.10 gearing, i believe? on 29" tires

i'm looking to go up to probably 33s (Mickey Thompson Baja Claw Radial to be exact)
Is that too big for my stock set up? I know there can be issues with tires that are too large.
I don't do any heavy duty wheeling, but it is my DD
Thanks guys.

Do a google search.... I couldn't tell you how many threads there are with this exact question. But since you're here...

No. You can NOT fit 33's on stock suspension. 31's fit stock. 32's with 2" lift. 33's will fit with at least 3" if you're ONLY going to be on pavement. 4" is definitely better and needed if you plan to even do light trail riding. Note that the lift doesn't have to be all suspension. It can come from a 1.25" bl (max bl height) with the difference made up in suspension lift.

My mistake, I meant more speed wise. I know people often lose the use of 5th gear with larger tires and no re-gear. I'm pretty ignorant to this whole aspect of the jeep world

I should've worded my question differently.

Do you have the auto or standard tyranny?

That was a dumb question. You obviously have the 5-speed. So you do have 4.10's as you stated. I have this exact setup. As long as you lift it properly, you will be ok for around town. 5th gear will be strictly for flat cruising with no head wind. And it will be more sluggish off the line. But you should be ok.

With that said I'm planning a re-gear, but very far in the future. I'm in college so I don't have the $1,200 for it right now.

Why do you want 33 inch tires? 31 inch tires will give you a better look and be cheaper, better running, and less problems (for your situation). It is amazing to me how everyone states, I don't drive off road much but how can i run huge tires? ok let flaming begin,:hide:

I agree. And I'll probably get flamed too. But to the OP, sounds like 2" bb and 31's 32's would fit your needs better. Less strain on your drivetrain but still the "cool" lifted look.

I was just gonna do a flat trade for my 29s and go 33. That didn't play out the way I thought and instead i'm probably just gonna go with some street-esque 32"

I've already got my 3" installed, might be just a hair shy, I picked up some stock JK suspension parts.
I feel like huge tires would be a waste, but it was gonna be pretty much free so I was going to make due.

33's are fit in two common ways on TJ's:

1. 4" suspension lift, with ~2" bumpstop extensions in front and ~2.5" in the rear. Requires a SYE/CV shaft.
2. 2.5" suspension lift, with a 1.25" body lift, with ~1-1.25" bumpstop extensions in front and ~1.25-1.5" in the rear. The 1.25" BL usually accompanies a 1" Motor Mount Lift to offset some of the driveline angles.

Either way you go, figure on some or many of the following components: longer front brake lines, extended sway bar links front and rear, gears, brake and steering upgrades to accommodate larger tires, SYE, CV shaft, bumpstop extensions, new shocks, adjustable track bars, and a rear track bar bracket.
