WARNING
To prevent personal injury, use the following guidelines
when installing a new tire or repairing a flat:
1. Always locate and eliminate the cause of the original
tire failure.
2. Do not patch or vulcanize a tire casing. These proce-
dures weaken the casing and increase the risk of a
blowout.
3. The use of tires other than those specified can
adversely affect handling resulting in personal injury.
4. Tires and wheels are critical safety items. Since the
servicing of these components requires special
tools and skills, Buell recommends that you see your
dealer for these services.

WARNING
Excessively worn tires adversely affect motorcycle trac-
tion, steering and handling and could result in personal
injury.
At regular intervals of 5000 miles (8000 km) or whenever han-
dling irregularities are noted, perform the recommended ser-
vice checks. See Table 2-3.
If tires must be replaced, same as original equipment tires
must be used. Other tires may not fit correctly and may be
hazardous to use.
