Thank you for the replies! To clarify, my last set of tires, the P7's were wearing evenly as I rotated every 6k. I did have issues with the wear on the Nexen's, my alignment was way out of spec before the P7's were installed.
I had the same impression about the alignment report -- everything was generally in spec to begin with. I'll ask about the left rear camber as Turbonut suggested. So the tire dealer had a bundle deal on the alignment (normally $99) and road hazard warranty (normally $88) called the Peace of Mind Package which was on sale for $147.99 (normally $187 for both alignment and road hazard). Their nationwide road hazard warranty includes, among other things, free alignment checks, lifetime balancing and rotations. So I did pay for the alignment but I've generally understood it's good to have an alignment anytime you replace the tires. I'm not sure I'd be eligible for a full refund on the alignment because the tire dealer could still charge me for rack time to verify the alignment, though I agree, it would've nice if they offered a partial refund if they didn't actual need to adjust any values.
Years ago, when I suspected the alignment was out of spec after I bottomed out after hitting a pothole, I brought the car to an independent shop and they charged me about $50 to confirm alignment was still in spec but they said the fee was for rack time only (not their normal fee to do an alignment), which I thought was reasonable.
If you divide $147.99 by 2 , it comes out to $74 for the alignment and $74 for warranty. If I protest the issue and say the alignment charge should've been rack time only, I might get a refund of maybe $25 or something like that, which doesn't seem worth pursuing.
BTW, I got a great deal on the tires on Cyber Monday ($100 off a set of 4 Goodyear tires) so I'm generally satisfied, minus the hiccup with the tire dealer misplacing my appointment and their non-existent for 2 years free courtesy shuttle, despite their advertising of a free courtesy shuttle at this location.
