15" Rims on 2012 JKU Sport

Will 15" rims fit on the JKU without changing anything with the brakes? Haven't gotten a clear answer if they will fit or not. Debating on whether to keep the stock 17"s or move to something smaller to reduce the cost of tires.

Some do, mainly Alloy and a very few steels. Must have at least a 3.75" back space for the most part

I run 15X8" MB Chaos 5 Alloy wheels with 3.75" BS with no issues

Now this isn't true for overseas models. They have a bigger caliper

15's will fit, as said the backspacing is what matters (3.75). Some of the popular choices are the MB TKOs and Kaos from Discount Tires and several 4 Wheel Parts offerings (Black Rock 900s, Pro Comp 8069 and 8179).
I was going to put 17" Duratracs on my JK and found that for $170 more could get 15" Duratracs and brand new MB TKOs.

Thanks a lot. I was looking at $300 or so a piece for 285/75/R17 BF M/Ts. I may go with the 15" rim now.

I put 15x8 US steelies on our Rubi. It's an '11, but same same. Pro Comp Steel wheels supposedly fit too. Alloys are a safer bet, but it is possible to find steel ones that will fit. You aren't going to get a definitive answer from any store or shop b/c their computer tells them it won't fit.

Check Walmart for your tires. So not joking here. I picked up 35x12.50x15 Mickey Thompson Baja MTR's from Walmart for $265 each. That's their standard price for that tire. Shocked the heck out of me, but I couldn't find anyone else that could beat that price. Not even Discount Tire. (Who also told me it was impossible to make this combo fit btw, as did my local Desert Rat.)

So I had the shoppette on base mount and balance, and I installed in my driveway. Then I bought mine a couple weeks later and now he wants the Mickey T Sidebiter wheels that came on mine. Oh well.

Whats your question? He asked for pictures...I've got the 15"s that fit.

Stay away from steel, they weigh too much and you'll end up bitching about gas mileage and acceleration issues, and then this thread will turn into a regearing mess.

Looks like the site no longer allows someone to link the site. Not sure why you would do that though because it is free advertising for your site.

Steel wheels had absolutely no affect on our acceleration or gas mileage.

Yeah thats kinda stupid as you pay to store your pictures there and it gives you the link to use.

What? Weight has a direct impact on mileage and acceleration, steel wheels are much heavier than alloy.

There is a ~8-lb difference between a 15" steel wheel and a 15" aluminum wheel. There is more difference than that just among different tire options. I'd rather have the extra 8# and bend a rim than save 8# "for fuel mileage", pay twice as much per wheel, then have to replace it after hitting a rock and cracking through the wheel... and having to spend that twice as much per wheel again... to save fuel mileage... that is negligible with 8# anyway.
Edit: Capper- didn't mean to come across as a d*ck here. Sorry if that's the way it reads.

On a bigger wheel you'd probably notice more difference, but I'm with you- I'm running 35s on steel 15s with literally half a ton of armor and still get better acceleration and mileage than most of the '07-'11 Jeeps with whom I go wheeling, despite that they're all on aluminum.

Didn't come across that way at all, we all have different opinions and the more opinions the OP gets the better. In 20+ yrs of jeeping I've never bent or broken a wheel, and have seen a noticeable difference in mileage between steel and alloy......but thats just me, and I may be in the minority....wouldnt be the first time, wont be the last.

Was that on a 15" wheel? I've changed mine up so quickly it's hard to say what effect any particular item has had on mine and in all honesty, as soon as I got the Jeep home from the dealer I installed 34x10.50-15 LTBs on steel wheels, so I really didn't have much opportunity to compare... not that it would have been a legitimate comparison when the LTBs are like lead weights compared to the stock GSAs.

Additionally, they use the Cragar as the steel wheel while they're using the cheapest available aluminum wheel. I spent $45/wheel on my steel 15s. It was the cost of two aluminum wheels shipped.

Furthermore, they insist that you need spacers with steel wheels. I've not seen anyone else saying that, but they needed something to put the cost of the steel wheels over the cost of the aluminum wheels to prove their point.

Just saying... they're only out to sell their product and on the shallow surface, they're good at it.

15" steel wheels vs the stock 17" alloys, there wasn't much difference. There was no noticeable difference in acceleration or mileage.

I've broken alloys in the past though. When I smash a steel on a rock, I just bend it back and we're all good. Had a friend in England that took his Land Rover to Germany when he left. He'd put a really nice set of alloys on it. Saw him a few months later when I went there on TDY. He showed me his wheel after he hydroplaned into a curb. Completely shelled itself out when it hit the curb. Looked kinda cool, wish I had a pic. While isolated incidents, I've had bad luck with alloys. But any time I smacked a steely, a ball peen hammer and a rattle can made it look like it never happened.

Thats not the question man...we're recommending 15" steel to 15" alloy, not 17".
