[QUOTE="Rustler, post: 1551490, member: 31456"] I typically run mnfgr recommended inflation (38 here, if I recall). I add a few pounds in the rear when towing my micro-camper (about 1,500 lbs). [USER=9341]@CoronaRaptor[/USER], they were absolutely mis-rotated (front to back, not cross rotated, see below for long and boring story) do you think that's sufficient to cause the cupping, or would that just cause excessive (but even) inside wear? What about the front end noise? I have read that a blown shock is a classic cause of cupping, but don't know that from my own experience. The mis-rotation is a whole part of the story I left out so as not to bore you all, but it's probably a relevant little nugget: On my last oil change/rotation, I asked them to look at the cupping and give me an opinion on what was causing it. When I picked up the truck, the tech's written report said: "Uneven tire wear, replacement recommended." To which I said, "no $h!t, that's what I told you when I dropped it off, what I'm interested in is what caused it." I was fed some BS at that point that "Raptor's just do that to their tires." So I went out to my truck and gave it a good look over, and sure enough, they rotated front to back. I returned with the manual to ask why they weren't following Ford's recommendation and at that point the service person clammed up I next heard from the head of the service department. Well, she has been very forthcoming. Admitted that the tires should have been cross rotated, and scheduled a quick follow-up to check alignment and the front end noise to be sure we know what is causing it (what I described above). At this juncture it is her position that the incorrect rotations (they did all three that way apparently) did not cause the cupping. But that there is some issue that is causing the noise in the front, and that may be related to the cupping. I tend to think that the mis-rotation is not the [I]cause[/I] of the cupping, but that it greatly exacerbated/accelerated the issue. What do you all think? However, I have reserved my rights on that issue while we check off likely causes. For instance, I would have felt like a **** if I'd insisted that the mis-rotation caused the cupping, only to then find out that the alignment was way out of whack and the likely cause. If the mis-rotation continues to look like the only known issue, then yeah, I'm going to fight like hell for a new set of tires. However, if there is another likely cause, I will look for something less than a full set as compensation for making the uneven wear worse. Maybe ask for my next set at cost with a free mount, or something to that effect. Needless to say I am skeptical of this dealership, but it's the only one within 90 miles, and as long as the head of service continues to take this seriously and work honestly towards a solution I'll give her a chance. What I am hoping for here is to be able to follow-up with the head of service armed with some better idea, and maybe relevant experience from you all, about what is going on. [/QUOTE]
