Tires & airing down on beach

Just purchased a 13 - Wrangler Unlimited MOAB. Came with the goodyear Wrangler Silent Armor Tires 245/70/r17. Curious how big I can go without a lift kit. Also was curious what most people air down to when going on beach. My old wrangler I let about 10 pounds out per tire. I had agressive tires. Not happy with stock tires on the MOAB. I got stuck a couple times backing up in sand, was able to get out. felt like I was burning the crap out of the clutch and engine though. Wrangler's shouldn't get stuck, lol

My '10 Rubicon does ok with the stock Mud-Terrain tires in the sand at stated 37psi, or so I thought. I've recently started airing them down to 16 psi and it's a different ball game. Someone told me 8psi is the magic number, but airing them back up is a pain in the *** in the little local pay-for-air compressors.

Without a lift you can do 255/80-17.

If you start lifting and changing wheels, etc. then possibilities are endless. But in bone stock form, 255/80-17 is the biggest tire you're going to safely get under a JK.
