I had 265/70/17 Toyo Open Country A/T IIs installed Saturday and took the truck to a local Toyota dealership for an alignment after. At home I was looking over the alignment report and, though I have a soft knowledge of alignment specs, the rear numbers looked off, specifically the LR.
Report from first alignment:
I did some searching on the forum and reached out to a couple of members I saw in several alignment threads for their thoughts (thanks Sungod & Synister). Consensus was that unless I had hammered a pothole or curb with enough force to cause a blown tire and/or bent wheel, the numbers were suspect. I bought the truck new and its 50K miles have been mild. Also, the number most concerning was the LR camber which as measured would mean that the wheel was angled top-in, opposite the expected result of a curb hit. Big deal because if the numbers were right I was looking at needing a new rear end to correct.
I took the truck back in, gave several reasons I doubted the numbers and told them to rerun the alignment. Sure enough, rear numbers from the second test came out as I expected them to the first time. (The Tech doing the second alignment said he "must've hit" the LF wheel during the test, throwing the out-of-spec .8*. So much for precision...)
Report from second alignment:
Moral: Human error trumps even the most precise instruments.
