Would you recommend a lift for a stock TJ for 31" tires?

So hopefully I will be getting an 02 TJ soon. I wont be able to check it out for 10 days so hopefully it is still there when I can go. The tires it currently has are Goodrich Long Trail, P225 75R15. I was thinking about getting some Goodyear Duratrac 31x10.5. Would you recommend a lift? Also would I have to get new wheels? I'm pretty new at all of this so I am trying to learn. Here's a picture of what I will hopefully get https://i.imgur.com/huCMF.jpg

They will fit just fine without a lift, but if you want a little more attitude then do a 2" budget boost lift. Paint the wheels black to save some money for your new tires and other add ons

I had 31s on a stock lift, no problems, but the Jeep looked better with a 2" lift. I did ProComp.

When my 99 was stock with 31s i did rub a little when on trail. The 2" lift helped that lil prob out for sure. And it looks SO much better.

Nope, I'd recommend first taking care of more pressing issues if you plan on using it.

Personally, I would install a 1" or 1.25" body lift (as far as answering the lift question) and run 31s with that.

The body lift will allow other important mods to begin developing (high clearance skid plates) and give those 31s some extra room if you choose to run some swaybar disconnects.

I put 31x10.5s on my 98 with stock alloys and they rubbed on full lock for right hand turns. Wheel spacers fixed it though

A 2" BB kit is only about $100...so why not?

Anyone have a picture of a stock tj with the 31's and wheel spacers installed?
I am curious about how that would look?

You do not need to add spacers if you simply adjust the steering stops a little bit to keep the tires from rubbing at full turn. 31 inch tires fit nicely on a stock TJ on stock wheels, however a small lift makes it look better to the eye.

Seems so simple doesn't it? Here's why not.

1) 31" tires fit perfectly fine at stock height and work well with stock travel. Contrary to popular belief, stock travel is fine and well-balanced. There are more areas that could use improvement.

2) Sure, you gain 2" at the belly, frame, rockers, etc. But you also now have steeper control arm angles, less wheelbase, and shifted axles. And I doubt you're taking new, longer shocks into the price and if that's the case, you now have very poor downtravel.

3) Resources would be better allocated toward the 'more pressing issues'--basic armor like a steering box and oil pan skid, replacing the stock belly pan with a high clearance unit, replacing the stock tie rod with a V8 ZJ unit for strength, and even ditching the stock control arms for more durable, adjustable arms.

Notice I didn't even touch on height. If you're gonna open up that can of worms, then tackle everything that needs adjusting. That's a lot more than $100 and you'll gain A LOT less than if you did the above setup instead.

1" lift with 31" Revo II's and 1.25" Spidertrax wheel spacers. Tires are even with the fender flares all around and do not rub control arms while turning. They do rub slightly on the fender during full stuff.



Suspension as it is today:

While I won't argue any of your points because I do understand what you are saying...but also the reality is "there is a always a better way to build a Jeep, no matter what you bolt on or modify". It's just money, understanding of physics, knowledge, experience, etc. You mention "basic armor" but maybe he would be better off with hardened steel armor or maybe he should cut the back half off and build a Juggy and do it right the first time.

Apparently I make certain assumptions.....and I bet the reality is closer to those assumptions than him building a juggy.

I could very well go on.....corners, sliders, etc. But I made the assumption that the OP is asking about 31's and basic stuff.....he's probably not wanting to get into scenarios where he'll need that kind of protection.

Anyway, here's mine years back on 31" KM's with stock suspension.


It went up on 2.5" coils for a while and here's a poser for scale (that stock belly skid is horrendous)


If I knew then what I know now, I would've taken my advice and kept it at stock height and addressed the more important items. Once I entered that mindset, it was all downhill from there.

So OP, don't think for one second that you'll be happy with 31's and it'll stop there......

Imped, this pic just reminded me another variable...that is if the owner has a hardtop and winch or other heavy items. If you were to have had another 400-500lbs of bolt ons, how would that have impacted your stock clearance with 31's? (I am not trying to suggest a 2" BB should be used to compensate the extra weight)

I don't know. I'm anti-weight and I make my recommendations based on that. For example, the amount of sprung weight now is probably less than it was in that picture and I'm fully armored. My full corners weigh 12 lbs a piece so even when it's looked at from an aggregate point of view, it's not much. I don't see it as an issue as long as you aren't just throwing on unnecessary weight.

I wheeled 8 years in my Jeep on stock suspension and 31" tires. Good times .

During that 8 year period, I spent what little money I had on armor.

No issues and the setup worked well for me...

You might want to get into all this stuff later on, but for now worry about getting first and enjoying as it is. Mine is stock with 30" Toyo Open Country's and I love it just how it is.

I've got a quick question, will the 31's be taller on the 15x7 rims? (instead of 15x8) I'm thinking about 31's but worried about rubbing. Probably not a huge difference and I put H&R springs on and got an inch lift but just wanted some feedback, thanks
