I know the 15" question is run into the ground but I need some clarification. Some threads say with minimal back space you are safe. Others say steel is fine but aluminum will rub brakes. Other threads say 15's work all day long, unless you have a Rubi. I've read it on the Internet so it must be true right? :shaking:

Does the extra articulation from the E-disco negate the ability to safely run 15's on a Rubi? Any actual stories of Rubi JKU's on 15's would be much appreciated. Pictures would be even better. I'm looking to run ProComp or Mickey T 15's and 33x12.5 Duratracs on a stock Rubi with circumcised fenders.

Cheers:beer:

I've got Procomp 8069 in 15x8 on an 07 rubicon unlimited. Tires are 35" MT baja MTZ. I haven't had any issues since running this setup since 2008. I just couldnt balance them with stickon weights inside the wheel

I'm running 15" steels with 35" tires. I did have to grind down the spreader on the brake caliper to get them to clear but I don't think it's enough to cause any issues.

The back brakes have no issues at all but the front ones are really close to the rim face. Apparently the front brakes calipers are not the same on the Rubicon as the non-Rubi.

Yeah good luck getting them balanced too. I think the 17" rims would be easier in that regard if you were going to do a lot of street driving on them. I just switch back to my street tires in between offroading trips.

I am running 15 x 8 MB Wheels Chaos 5 with Goodyear Duratrac on my Rubi with plenty of clearance even with stickon weights inside the rims. Go for it!!!!

Got some good intel from ProComp rep at Jeep and Truck Fest in Houston. He said Heep used 3 different OEM brake caliper manufactures on the JKU so fitting issues will be crap shoot. He also gave me some good advice and said to be sure and throw a fresh set of front pads on when you go test fitting rims. I thought the rub issues came from the O.D. of the caliper but apparently it's from the backside of the wheel spokes and outer surface of the caliper.

17's are sounding like a more expensive but much easier choice, ever more so if a lift and heavy duty steering gear are in my future. A big brake kit does sound like a nice option to deal with the new additional rotational inertia 35's would create should I get that stupid.

I have MB72's in 15" and have sticky weights mounted inside with no rubbing
on a 2011 Sahara.



Just remember if you go to a 15" wheel and decide to go bigger than 35" tires later, you will need new wheels as there are few choices in tires larger than
35's for a 15" wheel.

I'm running black rock steel wheels in 15x10 and 3.5 back spacing with 35x12.5 Pitbull Rockers on my 07 rubicon 2 door with no issues what so ever. I did not have to grind to make them fit. I skipped the sticky wheel weights and just went with the bead balancing.
