On the Hyundai Accent, a tire that wears evenly will eventually reveal the built-in tread wear indicators. These indicators appear as a solid, continuous band across the tread and confirm there is less than 2/32 inch (1.6 mm) of usable tread remaining. Replace the tire when this happens to help maintain safe braking performance, stable steering control, and reliable wet-weather traction.
