tire wear on one side only · patchy or cupped tire wear
One or more tires show wear that is uneven across the tread - more worn on one edge, in the center, or in a scalloped/cupped pattern.
Run your hand across the tread from inside to outside edge - a clear difference in remaining tread depth confirms uneven wear and helps describe the pattern to a mechanic.
Safe to drive, but address the underlying cause soon - uneven wear both shortens tire life and can indicate a suspension or alignment issue affecting handling.
