PARIS (Dec. 10, 2010)—Hutchinson S.A. has introduced a bicycle tire it claims is indestructible and 100-percent flat proof.
The Serenity tire, instead of having a pneumatic innertube, relies on a solid microcellular—yet elastic—insert. This is combined with a special tire, and offers comparable rolling resistance to a pneumatic system, Hutchinson claims.
One of the major drawbacks of previous puncture-proof bicycle tires has been the effort needed to push them along.
Hutchinson said the system rolls at about the same performance as a bicycle tire inflated to 50 psi pressure
