Down side of wide tires?

I'm currently debating running 12.50 vs. 13.50 wide tires on 37s. Even though it's only an inch, I sometimes feel like the 12.50 still look like pizza cutters to me.

Looking for owners who have ran 13.50 or wider tires to chime in here.

What, if anything, did you not like about the setup? I know it looks good, but have you ever ran into issues such as:

- Huge drop in MPG due to rolling resistance.

- Not fitting into a parking space due to the rig being too wide.

- Tires flinging too much crud or water on pavement.

- Balancing going out, or tires causing the Jeep to mis-align.

- Anything else?

Has anyone decided to run a smaller or narrower tire after running a wide one?

Thanks in advance.

Wider tires will have a few major effects. As you stated, they will decrease your MPG more than the 12.5. Your Jeep will also wander more on the highway at high speeds due to the extra width so it will be harder to maintain lane. Also, the extra width will make it harder to turn, so, for example, with a 37x13.5 you will definitely want hydraulic steering assist. Wider tires are also heavier so that will further effect power/MPG. The width in parking shouldn't be too much of a problem unless you are running a wider axle as well such as a Dana60. It also puts more stress on your C's, especially if you run a low BS wheel. And yes, unless you get extra wide fenders you will fling everything on the road/trail up, but that happens with 12.5" as well. Oh and unless you have a 4" or less BS wheel you will probably rub on full lock. That's all I know, hopefully someone else with some real world experience will chime in. Good luck!

There are plus sides obviously, but they predominantly come into play off-road. You will get more flotation in sand and enhanced grip in rock and mud. Just throwing some.positives out there

I'm in snow country... We like tall and narrow with deep tread. I prefer to not ride up on the snow and drop in...

Notice I did not mention snow. Only sand, rock, and mud . But that does bring up a point. To the OP, what type of wheeling do you do? That could play a role in how wide of a tire you should get.

What happens when the snow is <18" deep? Or however tall your belly pan is.

I have been known to "push" it straight for a while slow and steady. Then I will start the "y" drive trick...push slow turning a bit to the left of your chosen path...back up...push slow to the right of your chosen path...back up...repeat...

It's slow, and sometimes is less than effective...but i have always got that "pilot's" prerogative of going back where I came from...

And trust me...I love tall and wide... I like the look, and I like the performance in everything except snow... I think it just depends on what you plan to wheel in...

There is some snow that will let you go over the top with wide... it just seems i always find a spot that drops me in...and i hate shovels...

I have 37x13.50x17 on my Jeep, i feel they are too wide.

To answer your questions;

Cant tell you MPG, ive stopped thinking about it but with the diesel im still above 20mpg.

The extra overall 2" will not make parking any worse unless you also get deeper backspacing. I have full width 1 tons, its hard to park no matter what lol

They fling a ton, especially because i have no flares, but i dont worry about it well because its a Jeep and it never stays clean for too long.

I have no balancing issues, my tires arent even balanced correctly, have no steering stabilizer and they track straight with no steering wobble.


I would personally go with the 12.50 as i like the skinnier tires, and i drive in snow and slush and they really like to float and wander through the powdery stuff. They are also heavy as hell but then again these paericular tires are heavy, other then that though theyre fine tires, just not my cup o' tea.

This article gives a good perspective on why "pizza cutters" may be the best choice in most situations:

I personally like the 12.50's better for looks and 4 wheeling, but that is just my opinion. I have owned several sets of 12.50's in the past, but not 37's. I could see why you might think they would look too tall and not wide enough. Obviously your mpgs will differ from 12.50's vs 13.50's and with a tire that large it is pretty difficult to get it balanced out, regardless of the width.

If your state requires to have your tires completely covered by the flares too, check out the styles you are considering and that may sway you too. Your Jeep and money, enjoy both of them while they last, and post pictures!

I am developing better understanding and more respect for the factory STOCK Jeep, and most especially the Rubicon with 255/75/17's, a narrow tire. Beginning to believe that I will be happy for a long time, if not always remaining stock except for skids in tender areas underneath.

A factory Jeep is very capable the only downfall is when pushed to tough challenges the stock parts arent strong enough, if you were to skid the bottom, get beefier steering pieces and stronger control arms and some beefy axle shafts on 32" tires you can go fairly any where until its needed out in 5/5 black trails in the west.

Educate me. 5/5? I've seen ratings like 1 through 10, with 9-10 being most difficult.

Only downside to any tire is that you always want bigger, 12.5 included.

My guess is mostly mild rock, mud, streams with a beach trip every once in awhile. I don't think I'm interested in deep mud or climbing cliffs but everything else is fair game. We don't get too much deep snow here in Georgia, but I am concerned with safety on wet pavement. I don't speed in the Jeep but if I find a puddle, I will jump in it.

Did you buy the Jeep with them on? Just curious why you're running something you don't like.

x2 snow/rain will handle worse with the 13.5inch. The more weight on less width is better. Thats why pizza cutters are so popular with vehicles. If a car had 14inch wide tires it wouldnt handle in rain or snow as well as 8inch wide tires.

Sorry for the lame example lol.

However i agree 12.5 on 37s looks well kinda awkward lol. As long as you dont drive reckless 13.5 will be fine especially offroading.

Nice, front D60? I ended up with an effective 2-5/8" backspacing with my Walkers. A bit much, but they're 5x5.5"..ready for a D44/D60 hybrid...someday

It's pretty dry reading, but I agree completely the tall narrow tire advantages. I think the prefect tire for my jeep would be a 34-9.50 cut thru the mud, not push it in front of you.
