Off Road Capability

Cant decide if i should get 33s or 35s. When it comes to off road capability is there really that much of a difference between the two? I have a 2010 sahara auto, and like every one else money is tight.

The only reasonable answer is "it depends". If you will be running in places where you will need a 2" higher ground clearance or the additional footprint when aired down, then it makes a huge difference. How often and how hard will you offroad? How much daily driving do you do? Are you willing to regear fro the larger tires and possibly replace other drive components?

If you aren't sure, sneak up on it with tires your current size or just a bit bigger.

To tell you the truth there is nothing that will inprove the offroad capability of your jeep than lockers. You cant even make it throught any trail without a good ol locker 35" tires aint s*** without them. But I would go with 35s not only for off road but for looks 33s look small compared to 35s sadly. But good luck with your decision.

You get 1" more clearance, the tire is a total 2" more but you only count the radius for ground clearance with is half the diameter. So you have to weight if the 1" gain is worth it and on the trail it could especially in rock crawling. But then too you are adding more stress to your Jeep for every size tire you increase to especially a non rubicon with d30 front axles. To me the extra inch isn't worth it but to many it is.

Your biggest issue will be if you stick with 18's then the brand of tire may limit you to the tire size. Many Brands don't even have 33's and/or 35's for 18 inch wheels depending on the brand. If you are buying new wheels then you have more options if you buy 16 or 17's which have a lot better selection. Then you can even look into something like a 315/70/17 which is a 34.4" tire.

Size wheel and the brand of tire you like may dictate the tire size

Don't know if these numbers are accurate....past experience suggest for each 10% improved performance costs about 50% more than stock equivalent components.

I accessed a ton of mighty impressive outback trails in a 1945 CJ2 with stock 16" military tread tires, and the platform was pretty unsophisticated.

A lot of what we do to our Jeeps is for little other than profiling and styling and has little effect otherwise.

How you spend your $ is subject to your own whim and sense of style.

If you aren't quite aware yet of the massive increase in costs associated with the jump in tire sizes from 33 to 35 to 37, read some more and check out youtube. See what the catalogs are charging for such upgrades and decide if that's in your budget, and where in your sense of priorities each component fits.

The stuff I want for mine could easily crush a $10k mortgage, and I'm not even interested in doing any serious mudding or rock crawling.

When you off road have you run into trails/obstacles that you wanted to tackle that you couldn't manage without bigger tires? Has this happened a lot? If so, which tires would you needed to make it?

I ran my stock tires for a while before I hit a number of trails/obstacles that I couldn't manage and then I upgraded - same with my lift.

I try to not upgrade until I need to do it to tackle obstacles and trails that I can't without the upgrade.

Get 33's. The work you have to do in order to run 35's is just too much. You will easily need a regear since you need an auto. You would have to get the axles sleeved and get bigger brakes and a lot of other stuff. If we are just talking about the tires, it's only 1 inch of clearance difference. Get 33's and if you need more clearance get a 3 or 3.5 inch lift and that will get you through anything(provided you have a winch)

Thanks for all the input guys. I have done a lot of research, and i am probaly leaning towards getting 33s with 2.5 inch lift. Thanks again

Since you'ren Jersey, what kind of terain are you whelling? If you're running in the pines, you should get mud tires and a snorkel before getting a lift. If you're going to climb rocks at Rausch, then look for bigger tires to gain ground clearance and plenty of armor. The terrain dictates how you build.

Even with all that, your Jeep will be no more capable than the person behind the wheel.

Tire type will have more impact than tire size as far as capability. Since you have a Sahara, I assume you are running the stock SR-A's or what ever the street tire they put on Sahara's is. Those things weren't really designed to take you very far offroad. Better tires, some armor and a winch will set you up nicely. Lockers are always good, but lots of Jeeps with open diffs go lots of places.... Wheel till you figure out what your biggest problem is, then you'll know where you need to spend your $ first.

Then I switched to 35's and put an auto-locker in the front. I started to pop the front u-joint caps off of both front axles. Never seemed to happen off-roading but driving down the road.

Yeah, I've heard auto lockers are tough to drive in the road. It takes "technique"--as I understand it, you've basically got to lay off the gas when turning to minimize the torque going through the locker to let it unlock. They're also terrible in the snow.

Looking at your screen name, I can't help but wonder: Any relation to the famous acoustic guitar brand?

I ran 35x12.5 Pro Comp MT's with 4:10 gears on my X and didn't like it.

Here's why;

35's = 11 MPG, only useful in 4Low off road. Engine lugs in 4H up hills. 2wd was very slow to get up to 65mph. Braking distance is long, esp triggers frequently on curves.

33's = 15 MPG, 4H and 4L are both useable. (33x12.5 Pro Comp MT) Acceleration on highway is acceptable. braking is a little longer than stock tires. Esp rarely comes on.

32's = 18 MPG, all gears fine. (Stock 32x10.5 BFG) Highway speeds are easy, esp only comes on when I try to do doughnuts in gravel.

Granted I did have more clearance with the 35's but highway handling wasn't great (swayed with fat sidewalls) and MPG was simply awful. 8 MPG at worst.
I rub the skidplates a bit in the ORV trails with the 33's but don't care.

Did you update the speedo for the tire size changes? What skid plates do you rub????? You mean the front air dam? There is a lot being said here that confuses me. You have 4:10 gears on an X? Sorry, I'm having a dense Monday.

I put 33s on my Sahara on 16x8 ProComp alloys with 4.5" of backspacing. The money saved on rubber paid for the wheels at the first tire change and was money in the bank at every subsequent tire purchase.
33s took me everywhere I needed/wanted to go, were easy to live with, easy to find in a hurry, etc.

2.5" lift too.
