My question is whether the cupping issue was likely just from my failure to rotate the tires?
I put a new set of AT3s on the truck for unrelated reasons (nail in unrepairable area + near end of treadlife) and I’d like to avoid a recurrence of the cupping problem. The truck tracks well so I wasn’t planning on getting an alignment done, but I’m reconsidering. Most of what I read about cupping points to alignment issues (and not failure to rotate) as the usual cause of cupping. Does that sound right?
Thanks!

Is it lifted? If so what method and how tall?
Have you ever had it aligned? Do you have those specs?
Ever replaced the shocks / Struts? If so what brand?
How many miles did you get out of your last set of tires?
Anything else you can tell us?
