Moabs with big rubber
 
I want to keep my factory 2012 JKUR (moab) wheels but get bigger tires. I'd love to hear and see what non-OEM tires are being ran on the factory rubicon wheels

i run duratrac 35s on the stock rims, no issues. you'll just need 1.5" spacers.

37" (35" :rolleyes: ) km2s with 2" spacers. Minor rubbing on the frame rail.

You "can" put much bigger tires on the oem 17" moabs BUT.......

Check out the tire manufacturers RECOMMENDED RIM WIDTH.

The oem 17" Moab wheel is a 7.5" rim width (iirc)

Most 33" tires have a rim width margin of 7-9"

Most 35" go from 9-11"

Etc...


If the tire is too wide around the rim (not the outside traction patch-but the actual inside which makes up the bead) the chances of having a tire roll off the rim, breaking a bead etc is high.

Take it off roading/airing the tire down can be asking for a blown tire/breaking a bead/shredding the tire off the wheel.

Go ahead, but consider where and when you are going to make sure you can be reached by a tow truck...

Remember the actual WIDTH of the rim is only 7.5" wide.

Hence it is a 17" x 7.5" wheel.

Is that the stock bumper with the plastic skin removed?

Take it off roadi g/airi g the tire down is certainly asking for a blown tire/breaking a bead/shredding the tire off the wheel.

That's not how it works on large sidewall tires . The extra .5" of width isn't going to make a whole lot of difference. The more narrow the wheel gets the more the sidewall has to roll in, which causes the tread to be sucked down as well resulting in a no longer square foot print. The narrow side of wheel spec for tires is purely to put in a margin for the most efficient foot print from the tire as possible. Also, the recommended width doesn't increase with tire height, it's width. My 37x12.50r17 KM2s specify a recommended narrow rim width of 8". The 37x13.50r17 tires ill be getting next recommend an 8.5" rim

La dee ****in' dah

Yes, and cut down as well

I air down to 9-12psi every time we go out. We go out a lot. I have never "rolled" the rubber off. To the trails or DD. We run 27psi on a load range C Mtrk. at freeway speeds of 65-75 rims are Steal, 15x8 with 3.75 back space 35.12.5x 15.

I live in az were the heat can melt the rubber off tires. We wheel it here and every year we got to Moab and at least two trail areas in Cali, like the Rubicon, Dusy, Fordyice, Big bear/ Johnson valley. We DRIVE it there and back.

Now what Vett might be some what close to reality here is:
as the rim dia. goes up there is "Less" side wall to make up the "pinch". The ratio of the side wall to rim size is an issue. But we are still talking handling not failure. unless you are on 20"x7 and trying to pull over a 35x12.5x20 now we have a pinch that can not be over come.

Here is where the guy with the 37" on 17x7.5 has the ability to over come the pinch better than the guy with 35"s on that rim. Much like I have over the guys with 35"s. my ratio is the same.

But with the "MANY" jeepers that run these how many 1000k total miles for how many decades?

If you get a 10" wide rim as per tire guys specs on a little 35x12.5x17 and air down to 9" it will lose bead. The outer rims edge will get hung up on rocks.

that bumper and the fenders look great btw!

OregonVette 06-13-2013 07:00 PM

LOL!!! okay. You got me. No no... Go right ahead. Hell, you should probably stuff 37's on there too. It'll work great, just like that one guy on the internet. Trust the "fact" from an internet forum. lols

Better yet, when you read that the oem rim is 17" x 7.5" just close your eyes and pretend they are 17x10. Poof! Good to go!


oh, btw... 222doc. We are NOT talking about 15" rims at all. The OP asked what is the biggest tire for the 17" x 7.5" rim. What most weekenders, internet toughguys & mall crawlers forget is RIM WIDTH. BTW... That's really cute you drive to moab. So have we... And also to the Arctic Circle in Alaska & down to Quintana Roo. But, yeah, us overlanders don't care about reliability and field use. I just want my jeep to "look" cool. (insert sarcasm)....

For the record The oem rim width is 7.5. It has NOTHING to do with it "fitting in the wheel well" or "rubbing" fenders etc.

:) But, don't take my word for it. Go ahead and put 37" rubber on your 17x7.5 rims! LOL!

Personally, we have 35x12.50 tires on stock Moab 17x7.5" rims. Does it work? For us yes, maybe not for everyone else. I would not go with a shorter tire this wide, but don't see a problem with 35s or taller.
The tires are Toyo AT IIs.

Butterjeep 06-13-2013 07:48 PM

I run 33's on my 17's and would have no qualms going 35's or 37's on them in the future if I decide to go that route. I like the factory wheels, they are simple, look good and are easy to clean.

Let me help you. There are 3 things you can use to cure your stupidity. The first one is called reading comprehension, the next two are called math and physics. Try them on for size.

Cute.

23 year old mods talking internet toughguy language and calling users stupid. Bravo. Get back to me when you become a man. Thanks, son.


:thumbsup:

spyder6 06-13-2013 08:27 PM

My age and status is irrelevant, and I'm sure I've done more things in my life to earn my status as a man than you have. And I haven't called any users stupid, other than you.

But I'll give you this, here's your opportunity to make me look like an idiot. I want you to explain in detail why you're right and were wrong. Because so far you've only made your single claims and glazed over all of our rebuttals.

Come on manly man, fight your man battle with your man meat. Man.

My opinion is different things for different people, that's the great thing about jeeps is that they are unique in a way. I see no problem running 35s on stock 17s but I do understand the advantage of running wider rims.it depends on your wants an needs solely and only you can decide that in the end, but yes you can fit bigger rubber on stock rims.
