I'd disagree with your analysis of sun tire, not that it matters much now. They screwed me 2 different times with about 6 years in between.

My first experience with Mavis, was a phone call asking if they would honor sun tire warranty, this was about 20 days after the sign changed they said yes.
I show up, they do the work, charge me and would not back off of the charge denying the phone call altogether.
