I had heard that for 2015 the spare tire carrier was beefed up to 85 pounds, but I am having a hard time confirming this. My wheel and tire combo is ~82 pounds. I am going through my build list and trying to figure how far down I can go before I have to change out the tire carrier. I have my lift, wheels, and tires, and sliders go on this week. Oil pan and transmission skid going on this week as well. Trying to figure what is next.
