The secret behind Skylite's toughness and light weight is a foam core
surrounded by a durable rubber skin. Unlike hollow tires, the foam
provides strength and bounce absorption.
The outer rubber skin gives Skylites excellent wear characteristics.
In addition to eliminating dead weight, Skylites have better balance
and, unlike hollow tires, cannot lose pressure or go flat.
