Tires
For the best performance, you should
replace a tire before the tread depth at the
center reaches the following limits:
front
rear
If the wear indicators are visible, replace
the tire immediately as it is no longer safe.
Tire Repair
Refer to Saf ety Precautions
We strongly recommend that you replace,
not repair, any tire that is punctured or
damaged. As discussed below, a tire that is
repaired, either temporarily or
permanently, will have lower speed and
performance limits than a new or
undamaged tire.

A temporary repair can sometimes be
made in an emergency situation.
However, since a temporary repair may
not hold, you must ride very slowly,
preferably without any cargo or passenger,
and have the tire replaced or permanently
repaired as soon as possible.
(For more information on temporary
repairs, see
