Mamba (MR-1) Wheels vs Stock Moabs
 
R17873B6 - Mamba Offroad Type MR-1 Black Wheel with 5x5 Bolt Pattern in 17x8" Size & 4.75" Backspacing - Quadratec

I was considering buying the above rims to replace my 18s on the Sahara I have ordered. I know these rims are basically the exact same wheel as the stock Moabs, but was curious about the backspacing on them. I thought I read somewhere that the backspacing on the stock Moabs was 6.25" and the above wheels list 4.75" of backspacing. I am correct in this? What kind of issues does this present if I want to go with the stock tires (32s) that come on the Rubicon and the like. Does the 4.75" of backspacing listed for the Mamba rims mean they are set up for larger tires than the 32s that come on the Mojave and Rubicon models?

Thanks for any help you might provide.

Correct, being that they have 1.5" less backspacing, they will stick out a little farther for better clearance with wider tires. That doesn't mean you can't run stock tires.

Thanks for the reply ... so basically these rims provide a wider track off the get go and if I were to run 33s or bigger that makes it so they are more likely not rub, correct?

Exactly. The Mambas are nice, but I just don't think they are worth the price. You could always just throw on some spidertrax spacers and paint the inlays of some stock Moabs and get the same basic effect. Just my 2 measly pennies.

Correct. But like stated, you could pick up some stock Rubicon rims, probably for cheap, and run some $100 wheel spacers to get the same effect.

Yeah, I've really pondered going with these over my stock Mountain wheels. Could paint them graphite and they'd look almost identical, but with better backspacing and I could get rid of my spacers.

It's the price that's holding me back--tires are more expensive for 17" and 18" wheels than for 16" and 15" wheels, and 17" and 18" wheels are more expensive than 16" and 15" wheels to begin with. So buying another set of 17s is basically foolish from a money standpoint--you're spending more money for the privilege of committing yourself to more expensive tires. And in the case of the Mambas, you're doing it for wheels that look basically like what you've already got or can readily pick up on Craigslist. Financially, you're just better off getting 15s or 16s.

Of course, if you like'em, you like'em. Lots of what we do for our jeeps is foolish from a money standpoint! :thumb:

Husker4theSpurs 06-21-2011 08:48 PM

These seem cheap at $179/wheel versus $339 I've seen for stock Moabs.

They come in black (same as mineral gray stock wheels) so they wouldn't need to be painted. My thought is ... I ordered a Sahara package and would like a more aggressive tire and the options are limited with the standard 18s that come with the Sahara package so I'm just thinking of getting these wheels and maybe adding a 2" Budget Boost lift and some 33s for tires. I will see how I feel after my Jeep comes in (hopefully early September).

cavsvet74 06-21-2011 09:15 PM

You don't need the lift to clear 33" tires.

Just an fyi.

What makes you think black=mineral grey? The pics I've seen of the black Mambas look black, whereas my Mountain wheels are indeed graphite grey. They appear very different to me.

Regardless of color, there's nothing wrong with your plan. It's just going to be more expensive than going with say a 15" wheel set up. Both for the wheels and the tires.

For example, 15" MB72 wheels? $93 each. 33" Goodyear DuraTracs to fit? $168 each. By contrast, 17" Mambas? $180 each. 33" Goodyear DuraTracs to fit? $255 each.

So the MB72 set up runs you $1300 for five wheels/tires, then you spend about $840 for every subsequent set of tires. The Mamba set up runs you $2175 for five wheels/tires, then you spend about $1275 for every subsequent set of tires.

So the Mamba set up costs almost $900 more out of the gate and more than $400 more at each set of new tires. They do look stock though and avoid the need for spacers.

Is there a performance advantage for either size wheel for a given size tire? I would think the 33 on a 15 would soak up more than a 33 on a 17, but would it also be more vulnerable to having the seal broken when air'd down?

That's about how I understand it, yes. But I claim no sophistication regarding tires.

I am trying to figure this wheel thing out myself. I believe that the Mamba rims with 4.75" BS compared to the OEM JK wheels with 6.25" BS allows you to run wider tires without rubbing. ie...backspace and offset has more to do with tire width than it does tire diameter.

Yes. Read here: (http://www.jk-forum.com/showthread.p...274#post211274), especially the little diagram at the bottom.

I guess it's kind of an assumption by me but the other two colors of the MR-1 look almost exact to the stock colors despite being named a different color. Can anyone confirm their similarity or exactness in color to the stock Moabs?

JPWheelin 06-22-2011 06:21 AM

It looks like they have 4 colors:

Mamba Offroad Alloys - Type MR1

I would think the silver machined would be closest to the normal stock color. I don't think they really have anything that matches the COD/Mountain wheels (mineral grey, which is a graphite color as MTH mentioned). In these picks, the black does seem look like a dark gunmetal color, but it is darker than the mineral grey. Their gunmetal wheel is machined, so the face of the wheel looks silver. The inside of the wheel looks like it might be closest to the stock mineral grey.

...but Husker, I don't see why you need to match the stock color. MTH was looking to match the factory color because the mountain edition has the grill and bumper accents painted the same color. For your Sahara, I think you could pick any color you like.

You may be right about the black Mambas being darker than the Mountain/COD/Mojave wheel.

Ideally my intention with my Sahara is to make it look like a Mojave (without all the BS stickers and lizard on the seats), so I was planning on removing the aluminum bumper inserts that come on the Sahara and replace them with the mineral gray inserts that come on the Mojave/Mountain editions. So if these black Mambas are actually darker than the Mountain/COD/Mojave wheel that would kind of throw that idea out the window.

Regarding backspacing ... I am a bit confused, so the more backspacing a wheel has the further out from the body the wheel will sit? So the factory wheels have more backspacing (6.25" vs 4.75") than the Mambas so does that mean they sit further from the body than the Mamba wheels would? So the Mambas would accept a smaller tire than the factories without rubbing? Or do I have that completely backwards? Thanks guys ... I have looked at information on backspacing and am still confused.

I believe the back spacing in numerical terms works reverse. If I am not mistaken. Being the higher the number the closer to the body it is. Thus creating a narrower track. And Potentially causeing rubbing.

The bumper inserts are the same on the Sahara and the Mountain. So you're good there. :thumb:

As to the wheels, here's a recent thread about somebody who used Rustoleum wheel paint to paint stock Rubicon wheels and duplicate the look of Mountain wheels. Looks very convincing to me, and is why I mentioned earlier that I had originally considered getting the Mambas and painting them.

You've got it backwards. Less backspacing pushes the tire further out. Read here and scroll down a bit to check out the diagram, which shows why lower backspacing means the tire protrudes further.

Thanks for the info! Actually the Sahara and Mountain/Islander/Mojave models both have bumper inserts but they're not the same color - Sahara's are aluminum looking while the others are mineral gray.

I was so sure you were wrong about that, but Google images seems to be confirming your view. Learn something new everyday! Thanks. :thumb:

Husker4theSpurs 06-25-2011 11:47 AM

These look pretty darn close to the mineral grays to me ... anyone else have a close up of the actual mineral gray Moabs? Here is the "Black" Mamba MR-1.http://www.mambawheels.com/Mamba_Ima...amba_MR1_B.jpg

A bit darker I suppose, but hard to say with the light.

roxbury29 06-27-2011 08:39 PM

both are nice, can you get away with 285 or 295 with the mamba..

1 more ? - do you think you can put the Jeep center cap in the mamba wheel...
I am looking for a black wheel, very tempted to paint them or have a shop paint them
