Tread wear
Warning! Replace tire immediately with a Harley-Davidson specified tire when wear bars become visible or only 1/32 in (0.8 mm) tread depth remains. Riding with a worn tire could result in death or serious injury.
Harley-Davidson tires are equipped with wear bars that run horizontally across the tread. When a tire is worn to the point that the wear bars are visible, or 1/32 in (0.8 mm) tread depth remains, the tire can:
Be more easily damaged leading to tire failure.
Provide reduced traction.
Adversely affect stability and handling.
Replace the tires with new tires before the tread wear bars appear:
See Figure 1-16 or Figure 1-17. Indicators (1) on the tire sidewalls point to tread wear bars (2) in the tread.

Tread wear bars appear in the tread pattern when 1/32 in (0.8 mm) or less of tread remains.
Tire damage
Replace tires with new tires when:
- Tire cords or fabric are visible through cracked sidewalls, snags or deep cuts.
- A bump, bulge or split is found anywhere on the tire.
- A puncture, cut or other damage cannot be repaired.
