Beadlocks or not?, big difference in what you can get away with. Riding style also enters into the equation. One of our members ran 8 lbs. on stock wheels for a couple thousand miles with no problems. I got uncomfortable at 12 lbs. because sometimes I ride like my hair's on fire and come down hard on a front tire. Note that I'm in a Talon fwiw, but weights are similar. I'm running 8 front, 9 rear with beadlocks and the guys I ride with swear I'm way too high for our slow rock crawling. But I swear that, once a day at least, I'm hitting the rim.
There is no answer, pick a number, give it a try.
