As noted by the prior poster, they transfer them as part of the install. Just discuss it with your tire place.

I'm not sure that the lower backspacing of aftermarket wheels really causes any signifcant loss in turning radius. I suppose in theory they could . . . but the reality is that you're only talking about two inches or so at the edges of your front axle, and that's not accounting for the change in tire size . . . I dunno.

There certainly was not any noticeable change after the swap.

But even if it did cause some sort of drop in turning radius, the fact is that I needed the lower backspacing for the 12.5" wide tires. Otherwise, the tires would have rubbed areas within my wheel well, and THAT would certainly drop my turning radius as I wouldnt' be able to turn the steering wheel as far without rubbing.

In any event, the Black Rock D-Window alloys have 4" of backspacing.

Lusus_Naturae They transfer the sensors if you do it at the store - if you order them you should prepare to buy a set from them to have installed when they put them together before they ship.

Purchased these through my local Discount Tire after some outstanding assistance from the Discount Tire Direct folks through PMs on this forum.

I've driven the 35 miles to work, and now can provide an initial review . . .

First up, cost. Discount Tire matched the lowest delivered price, gave me $55 each for my old Rubi tires ( ), $50 off for being a member of the Wrangler Forum, $50 off the wheels for Black Friday, and $50 off the tires for Black Friday, which brought the total to $1252.25 plus tax. On top of that, I submitted my $40 rebate through Goodyear as well as a $100 rebate through TreadLightly. I'm on the fence about whether I should sell my old Mountain Edition wheels. I might hang on to them, but if not, that's probably another $200 to $300 or so back in my pocket. That means I'm out-the-door for about $1000 for five new tires and five new wheels. Can't beat it.

Gearing. Here's where I was worried. I've got a 4 door, the old 3.8 engine, 3.21 gears, and I went up an inch in tire diameter and 2.5" in tire width. My hope however was that the super light weight of this set up would help offset some of that. (For those who don't know, 33x12.5R15 DuraTracs with a 15" alloy wheels is the lightest weight 33" set up available, even lighter than the stock Rubi set up.) Additionally, I was hoping the reduced rolling resistance from the DuraTracs (an AT tire instead of my stock MT) would also help out.

And? I was right. If anything, it is EASIER to get rolling from a stop with these tires. I couldn't believe it. I really thought I was going to have to refine my clutch technique, but nope. The stop-and-go low speed stuff is much better on these than the stock Rubi tires. Really, really happy.

On the highway, my RPMs have dropped a bit at the same speed on account of the larger diameter. But it's not much. It just means I've just got to downshift a little earlier on hills I would've downshifted on anyway. It's a non-issue.

Ride. Great. Smoother and quieter than the stock Rubi tires I am used to.

MPG. Right after I got the tires I filled up the tank, reset my MPG dash readout (as I do at every fillup), and drove 35 miles to work. My dash readout now says 19 mpg. That's around the high side of normal, which is generally anywhere between 17 mpg and 19.5 mpg. So that means my mileage has apparently either been unaffected or improved, and that's not accounting for the extra inch in diameter since I don't have a ProCal/Superchip. Very interesting. I'm going to have to watch that one.

Overall, very happy. Not a single complaint yet.

Questions? Comments? I'm all ears. And here's a few more pics.
Love your setup. I'm going with the same actually - I'm waiting on the 909's I ordered and buying the 33" Duratracs tomorrow. Also looking to get the stubby end caps for the bumper and throwing a light bar on top. Glad to see it looks as good as I imagined.

Only difference is the price here in Alaska. It'll be about 1700 for mine, all said and done. Nice job finding the deals.

One question (I am a Jeep rookie, please don't judge) - do you do anything with the sensors on your old wheels? Did you/can you transfer them to the 909s?

Interesting. I've been debating between 15" and 17" wheels. I was mostly focused on price but I guess I should also consider road manners.

I have a 2012 JKU. 3 times now I have talked to three different shops, (2) 4x4 shops and (1) DT store. All three have said this set up will NOT work. They will rub the brakes and wheels will stick WAY out. They insist I have to get the 17s.

Do they just not have the knowledge and experience?

Or are they just trying to get me locked in to paying $100-200 more each for tires?

There just seems to be so many people running 15 inch aluminum wheels on here with no problems. Yet all the the shops say no way it will work.
Not all 15" wheels will fit. The MB72, MB Chaos 5, MB TKO, Black Rock D-Window alloy, Black rock Viper, Level 8 tracker.... all of these will fit your JK without any issues.

Give us a call at 1.888.459.4080 and we'll be happy to help you with a set.

They're just wrong.

They have a computer system that tells them the stock sizes. Anything else is assumed not to work.

Show them this thread an ask them of they think it's either just all a vast conspiracy to get folks to buy wheels that don't fit, or if maybe--just maybe--they're wrong.

I want to order a set of these hub centric rings for my Black Rock 909Bs. Are you pretty positive that this is the correct size? I had a PM to Discount Tire about this last week and they listed a different size:

"The hub bore on the 15x8 (4" BS) 909 is 83mm which makes the applicable ring size needed 83-71.5."

Now I know the diference between 83mm and 87mm isn't much, I just want to get the right size. Can anyone else running these tell me which size they are using?

Thanks,

I checked out that site. No Black rock listed for wheels. We would have to get the dimension from the manufacturer.

Good find! I sent a PM asking DTD if they knew about these, if they were selling them, etc.

Here's a write-up: How Hub Centric Rings Work - JustForWheels.com

As I understand it, the recessed area on the back of the vast majority of aftermarket wheels is made quite large so they can fit many different vehicles. The stock jeep wheels and AEV wheels are by contrast hub centric--that is, the hub fits inside the space behind the wheel perfectly.

In a hub centric wheel, the weight of the jeep sits on the hub, which sits on the wheel, which sits on the tire, which sits on the ground. In a wheel where the recess on the back of the wheel is larger than the hub, the weight of the jeep sits on the lug studs, which sit on the holes for the studs in the wheel, which sits on the tire, which sits on the ground. So it's a question of whether your axle hub (hub centrict) or your lug studs (non-hub centric) are supporting the weight of the vehicle.

Hub centering rings fill in the gap, basically making your jeep's hubs the same size as the recess behind the wheel. Effectively turning non-hub centric wheels into hub centric wheels.

Not having hub centering rings can, in theory, lead to vibration and the like if the wheel isn't perfectly centered among the lug studs.

FWIW though, I've been driving on my 909s since I first started this thread without hub centering rings, and I've had no problems.

I was going to do the 2.5" Teraflex budget boost. On my new Jeep Sahara. Sold it for $350 brand new. I would've stamped and mailed the box to you just for the 5,000 + posts.. Nice!
