Our heavy SFA trucks are never going to be great on tires. Just the price we pay for good 4WD. That and not so great ride quality. A lot of things go into tire life. Compromising performance is a huge one.
I personally don't believe OEM tires are any less quality than some of the other brands that don't get selected for OEM delivery. Said another way, there aren't any OEM tires that are not also good sellers as replacements.
My truck came OEM with BFG Rugged Trail tires, if I'm remembering the model name correctly. I know I bought one set of replacements of the exact same thing. Then when it came time for the 3rd set, BFG had discontinued that tire model, and the BFG Rugged Terrain was the designated replacement. It was a beautiful looking tire to my off-road experience eye. I ran them long enough to blow one up, which tore up the bed of my truck pretty badly, and then barely caught a second one separating and ready to do the same stunt. I told my tire dealer I wanted those gone, and never wanted to see them again. We negotiated a buy-back and I purchased Michelin replacements. Yeah, I know, same company. But these have been very good to me thus far, and I'm sure they are going to age out before I wear them out. This Michelin is also an OEM on Ford trucks.
