Abstract
A new tire tube with a puncture resistance function was
developed. The tube is a two-chamber structure having an air
chamber and a liquid chamber, and the liquid chamber at the
crown-side half of the tube is filled with an anti-puncture sealant
during a manufacturing process. In a market test, it was confirmed
that the number of puncture cases were reduced by 90% in comparison
with conventional tire tubes by using the newly developed tube.
This paper describes the structure of the tube and the
characteristics of the tube rubber, and the manufacturing process
and durability of the tube.
