Finally got around putting the tires on. Took em to Seb at Specialty-Z and discovered the stuff I thought was no-big-deal, is actually bad sidewall damage on right front and rear tires.
Timothy Jacobson (the seller here:

Not a nice experience overall.
Big thanks to Seb and LJ at Specialty Z to inspect the tires and let me know that they are not road safe.
