Abstract: Tire has a casing defining a hollow interior, a fill disposed in the interior of the casing, and the fill including at least one layer having an initial diameter substantially the same as the initial diameter of the casing. The fill layer includes an expansion joint. When the casing expands the expansion joint expands and causes the first layer to substantially continuously contact the casing.

Abstract: The preferred embodiment is directed to a pneumatic tire having a plurality of layers of high density foam rubber formed therein and methods of manufacturing and installing the layers therein. The preferred method of forming the layers of fill to be inserted in the pneumatic tire casing includes the following steps. Forming an elongated strip of elastomeric material of a size sufficient to form at least two concentric layers in a predetermined size casing of a pneumatic tire at a manufacturing site. At least one dimension of the elongated strip is the same as at least one dimension of the two concentric layers when inserted in the casing. Formulating data sheet having information from which the elongated strips can be cut to form the at least two layers for at least one predetermined condition. Transporting the elongated strip of the elastomeric material and the data sheet to an installation site remote from the manufacturing site.
