I'm running 15x9 American racing with 35x12.50 Cooper STT pro. I'm using stick on weights now, but may go to balancing beads in the near future.

 

I have 15x8 American Racing Baja. They clear just fine. 3.75 backspacing. Also 33x12.5x15 Mastercraft Courser MXT. No rubbing. Weights are on the inside lip of the wheel

 

I took the plunge and ordered all 4 procomp series 52 as well as a set of 4 bfg km2s. (Awaiting arrival of tires) They fit but i found they have the bare minimum of space not necessarily because of the caliper clearing the sides but because the D rings are protruding into the rim that it almost scrapes the top of the caliper. To fix this i ordered a 1/4 in wheel spacer from jegs. It definitely gave me more than enough clearance but left me with too little stud space for comfort so i downsized to an 1/8 in spacer which should do the trick. And just to make sure i wasnt dumping my money i called extreme terrain and spoke to a rep and they verified that the series 52 is a direct fit to all 07-16 jks as it as listed on their site.

 

Dang, wish I could've chimed in before you pulled trig.

I run 15" MB Razors and am currently saving my pennies for 17's (mostly because beadlocks are stupid expensive and I'm in college). If I could've done it over again I would've went straight for 17's.

They are super hard to keep balanced. This might be due to my MTR/K's, but I've also noticed they're super spongey on the highway.

Don't plan on making any steering upgrades with those 15's. You won't have enough space; I bought a Synergy Tie Rod and had to sell it because the ends are too big. Can't do a drag link flip either. The sticky weights fit, but they might rub and make noise if not placed in the correct spot.

Best of luck.

 

Its not a permanent thing though. I figure its the easiest way to get an aggressive look. I like a decent amount of sidewall and running 32s on 15 will make it look more like 35s. Since my jeep is brand new im waiting awhile before i get a lift cause of my warranty. Once its up though im going with a 4 in long arm kit from terraflex with fox shocks and 35 in tires and 17 in wheels. Also regearing front and rear. This temporary setup will get me through the winter here in south jersey at least for this year

 

Been running 35X 12.50 X 15 BFG KM 2's o 15 X 8 MB11 Wheels for 8 months now.
No problems with weights, or anything else. Tires are cheaper and I prefer the way a 15" wheel handles off road.

 

How is the ride on the highway at 65-70?

 

When I changed the tires, I turned the TPMS to off road mode and dropped the air pressure down to 32 lbs . The ride is much smoother and I'm not wearing the center out of a set of ties ever 25,000 miles.

 

I'm running 15x8 A.R. outlaw 2 wheels on mine with 33x12.50x15 all terrain tires, no problems here

 

Vision 'D' Windows 15x8 3.75 BS, just test fit one and they cleared all calipers on my 2015 JKUR so I ordered 4 more. My 35x12.50x15 Mastercraft MXT's will be getting swapped onto them.

The Bart 15x10 4" BS Steel Wheels I initially purchased did not clear the calipers.
