Inspection
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)
See Figure 1. Arrows on tire sidewalls pinpoint location of wear bar indicators.
Tread wear indicator bars will appear on tire tread surfaces when 0.8 mm (1/32 in) or less of tire tread remains. See Figure 2. Always replace tires before the tread wear indicator bars appear.
When To Replace Tires
WARNING
Harley-Davidson recommends the use of its specified tires. Harley-Davidson vehicles are not designed for operation with non-specified tires, including snow, moped and other special-use tires. Use of non-specified tires can adversely affect stability, handling or braking and lead to loss of vehicle control, which could result in death or serious injury. (00024d)
New tires are needed if any of the following conditions exist:
  1. Tread wear indicator bars become visible on the tread surfaces.
  2. Tire cords or fabric become visible through cracked sidewalls, snags or deep cuts.
  3. A bump, bulge or split in the tire.
  4. Puncture, cut or other damage to the tire that cannot be repaired.
