Adding more lift and more rubber
Currently : 2014 JKU Sahara. 2.5'' Teraflex lift, 35x12.5r17 Goodyear Duratracs on 17''x(9''?) Fuel Mavericks.
I'll need to switch out the tires soon, 10k-ish miles left on them. I was thinking of bumping up to 37x12.5 or 13.5 Ridge or Trail Grapplers and adding a 1'' leveling kit. Does anyone know if there is anything else I need to do to accomplish this? Maybe switch to flat fenders but should I bump up to a D30 or switch out any other components? Mostly used for paved roads and overland, it is my weekend vehicle I guess.

If you're going to go to a 37, I'd stick with a 12.5" width as I'm pretty sure your wheels are 4.5" BS. Unless you are going to run spacers, 13.5 is gonna be a bit wide. 12.5 works with a couple washers added to your steering stops. I have ACE inner liners, and under full stuff my tire would still contact the liner just enough to leave a scratch. You'd need to address your fenders. In the rear, you might have to cut more pinch seam. Not sure how bad on a 2.5" lift, but 3.5" lift with factory arms leaves the rear tire offset towards the front of the wheel well....enough so that it looks a bit odd. It's much better if you have adjustable arms and can push the axle back. You might need to reassess if your bumpstops are adequate. A 37 is obviously going to stress components that much more.....steering joints/components as well as the axle/gears. Have you upgraded DL, TR, and ball joints? You didn't mention what gearing you currently have.....4.10 or lower you will likely not be thrilled with performance.

The extra mass and rotating inertia of those 37s will quickly overwhelm the stock brakes and make driving your JK anywhere an adventure you won't enjoy, especially in traffic where you might have to stop suddenly.
Upgrading to a set of our HD ball joints is also a good idea to beef things up for those 37s. https://www.dynatrac.com/rebuildable...alljoints.html
