My PS4 A/S (315s) are at 29K miles with 5/32” left on the rears. I should reach 30K before I replace them. The fronts (275s) had a blow out due to road debris, so they were replaced early. However, they were at 27K miles with 5/32” left when the debris killed them.
Before the AAD parts, which allowed for more alignment options, my square setup would barely reach 15K miles before the tires were done. The AAD parts are paying for themselves in terms of tire wear longevity.
