What size tires and lift should I get on my 2011 Sport?

Hey everyone,

I want to upgrade my 2011 Wrangler Sport by getting bigger offroading tires. I have a few questions regarding this:

1) What size tires? I know this is a broad question, so let me elaborate. I would like to significantly enhance my Jeep's offroading capabilities without turning it into a complete monster truck. Price is not too big an issue, but obviously saving money is nice. So basically I'm looking for the happy medium. From what I have seen and read, my gut feeling would be to get 33 or 35 inch tires, but I'm not sure. From here, can anyone recommend good brands?

2) What size suspension lift? I don't want to risk any rubbing. What's the general rule for tire size vs lift size? Again, can anyone recommend good brands? There are so many different lift choices, how do you pick one?

3) With bigger tires, do I need to upgrade my axles or gearing? I've read I do and I've read I don't on different threads. If so, what should I be looking into?


Thanks in advance!

Most people will tell you to go 35's and that would be the case if you had the Dana44 combo but you don't. With the D30 front axle the biggest i would go is 33in tires but that just my opinion.

just my humble opinion, but don't go to 35's unless you really want them, or really need them.


a lift of under 3" will suit you fine; look for a budget boost (coil spacers only) to either lift (same size front and back) or level (more front, less rear)

33's look/ fit nicely (I'm biased) with the jeep leveled (but you will likely want spacers for your stock wheels, or an aftermarket wheel with different backspacing to clear the suspension)

front leveling kit only, 33's




front leveling kit, plus 2" coils front and rear, 33's





I did not regear, and have been ok with the driveability of this combo as-is. most everyone will tell you you should regear when going to 35's (and many recommend it with 33's as well)

lots of people run 35s on the d30 front axle, they say anything above and you should strongly consider moving up to a 44 for the front according to what i've read.

lots of people like teraflex/aev suspension it seems. I run BDS 3" on my sahara and like it. If i was doing it again though i would probably go with teraflex.


If you want to avoid replacing a lot of stuff, i would do anything more then a 3" lift. once you do more, more things need replaced.

Agreed. If you want 35's, get them otherwise you'll be kicking yourself every time you see a JK on 35's pass by. Otherwise, 33's do look great also.

As a JK newbie, please check out the FAQs as a lot of your questions are addressed there. That said, get the size of tires you either need to show off (mall crawler or DD) or to off road the trails you want to. How you mod your JK depends on what kind of driving you want to do,and lift no more than needed to accommodate tires if you off-road to keep the COG low.

So, my suggestion is to look up the thread where everyone is posting pics of there Jeeps. (there is one for 2dr and 4dr) find the the look you are going for i.e. tire, wheel, height combo etc and ask the owners what they run so you can replicate the look.. EVERYONE has their opinion but everyone is not you.. Let the mods begin.

Back when I had the JK, I ran 295/(?)/17 Nitto Terra Grapplers for a while. I also ended up with a broken front axle housing.

I personally think 33" tires look great on a JK and will meet "most" offroading needs while allowing for decent mpg.

If fuel economy isn't a concern, then go for 35"s.

Either way, I would recommend looking at some sleeves for the front axle. I am sure that the vast majority of people have not or possibly will not suffer a broken axle housing, but it can happen. And it doesn't take "hardcore" abuse for it to occur. That's just my own personal feeling.

When I get another JK, it's likely going to be 33"s after a while, but I'm going to invest in bumpers/recovery first.

All good info-but

You don't say what your tranny is--stick/auto and

If auto, you're going to need regearing, even with 33" tires, if stick, you can run any gear you want to, but your MPG is goin DOWN-

My '08 JKUR runs 33.6" Hankooks/w regear and there's nowhere I can't go (he heh, be reasonable)-



I can get up to 18mpg and 14.9mpg towing--

Every jeep is different and every owner has different wants/needs---do a lotta homework-

As soon as you pick any tire larger than your stock 32" BFGs, your gonna wanna change many things-if auto, the tranny is a PITA/w stock gears--even 4.10 !

Good luck

JIMBO
