I have 35x 12.5 on the stock moab wheels with KM2's and a 2.5 lift. The jeep rides the same as stock, just slower.. I air them down to around 30 PSI, so far wear is normal. You will need spacers though, and also a spare tire extension bracket.

 

I'm running 35x12.5x17 Pro Comp AT's on the stock Rubi wheel with a 2.5 coil lift and spacers. I haven't had any problems or rubbing, but I drive mostly on the beach and local logging roads (i.e. not rock crawling).

 

37s, 2.5" lift, flat fenders, stubby bumpers, trimmed off pinch seams in the rear.

I do need to add some spacers in the front though, as at full turn they rub the frame. Granted, I have aftermarket wheels. Even with the spacers on a stock Rubi rim, you may still catch the frame at full turn.
Oh, and as Goody stated, you will want to regear. I have 4.10s and it's livable, but not preferable.

 

Do you think I could run 37's with my setup? I have 1" lift up front, 3/4" lift rear, and I have a 1 inch body lift on the shelf waiting for bigger tires. I could put on some longer bumpstops.

 

i think 4.56 gears for a manny is fine for 35s?

am i correct

 

You won't get 37's with that lift. You need 3.5 inches plus to get 37's. I've got about 3.5 inches with 35's and I run during extreme flex when wheeling.
