Tread Wear

WARNING

Replace tire immediately with a Harley-Davidson specified tire when wear bars become visible or only 1 mm (1/32 in) tread depth remains. Riding with a worn tire could result in death or serious injury. (00090c)

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 0.8 mm (1/32 in) 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 or Figure 2. Indicators (1) on the tire sidewalls point to tread wear bars (2) in the tread.
Tread wear bars appear in the tread pattern when 0.8 mm (1/32 in) or less of tread remains.
