1. Fill a small amount of air into the deflated inner tire till the inner tire is just bulged to
look round.
2. Put the hub on the top of a desk. Pay attention to the direction when installing the outer
tire. There is an arrow on the outer tire, and it must be consistent with the forward
direction of the wheel. Use one hand to hold the hub, and use the other hand to insert
one side of the outer tire in the hub groove.
3. Insert the air valve of the inner tire into the air valve hole. Insert the inner tire in the
outer tire clockwise and in sequence.
Make sure that the air valve does not tilt. Then, insert the other side of the outer tire in
the hub groove. Finally use a crowbar to install the remaining tire lips in the hub groove.
After installation, pinch the outer tire to check if the inner tire is pressed bythe tire lips
of outer tire.
4. Inflate the inner tire to 15-20 PSI, and check the safety lines at two sides of the outer tire.
Make sure that the distances from the safety lines to the hub edge are consistent.
5. Finally inflate the inner tire to 45-50 PSI. Tighten the air valve cap. Then, the tire assem-
bly is completed.
Note: Wrap the pointed end of the crowbar with fiber cloth so that it will not damage the
inner tire and coating of the hub.
