2019 Audi S4 — inside shoulder worn out while outside looks fine

BoxerMechanicish467Community StarterJun 30, 20262019 Audi S4 Premium PlusLong Island
2019 Audi S4 Premium Plus, about 108,000 miles. The tires looked okay until I checked the inner shoulder, which is much more worn. The car is slightly lowered. What alignment measurements matter most if I want to stop eating tires? If I figure it out I will update the thread. What would you check next?

Thanks, this narrowed it down. I am going to try the simpler check on the 2019 Audi S4 first.

Before you spend money, owner data points help more than a generic forum diagnosis on a 2019 Audi S4.

If it were mine, I would verify the cheap/easy branch on the 2019 Audi S4 before committing to a big repair.

Useful — I will report back after I verify that on my 2019 Audi S4.

I would start here: write down what you already tested so the next step is not a repeat.

Fair, but in Long Island, I care more about the thing I will notice every day than the spec-sheet extra.

One thing that mattered for me: in Long Island, I care more about the thing I will notice every day than the spec-sheet extra.
