Take my advice with two RAM DRW's under my belt. Give it 2-3k for the front suspension to settle in and take it to a GOOD alignment shop and have the TOE set 1/64-1/32. If you don't I can guarantee you front tire outside edge stepping.
Rotate fronts side to side keeping wheels in same position with moving tires side to side so rotation stays the same about every 15k. Leave rears alone.
Run 80psi fronts aLL the time. Rears 35 unloaded and 65 rears if running 9,750# rear axle. If less use the weight inflation chart and add 5psi to what it says.
Buy a set of Michelin's at Discount tire and sell the POS NEXENS as I can almost guarantee you tire separation at or near 25k.
