WARNING
Do not use a tubeless tire on a wheel de-
G
signed only for tube tires to avoid tire fail-
ure and personal injury from sudden
deflation.
When using a tube tire, be sure to install the
G
correct tube.
Always replace a new tube tire and a new
G
tube as a set.
To avoid pinching the tube, make sure the
G
wheel rim band and tube are centered in the
wheel groove.
Patching a punctured tube is not recom-
G
mended. If it is absolutely necessary to do
so, use great care and replace the tube as
soon as possible with a good quality re-
placement.

WARNING
New tires have a relatively low grip on the
road surface until they have been slightly
worn. Therefore, approximately 100 km
should be traveled at normal speed before
any high-speed riding is done.
NOTE:
For tires with a direction of rotation mark "1": In-
G
stall the tire with the mark pointing in the direc-
tion of wheel rotation.
Align the mark "2" with the valve installation
G
point.
