・未硬化ベースコンパウンドで作られたトレッドを準備するステップと、
・規定された量の未硬化挿入コンパウンドを未硬化トレッドに対して定められた位置で未硬化トレッド中に注入するステップと、
・トレッドを成形するステップとを有することを特徴とする方法を提供する。
・インサートをコアに対して規定された位置で未硬化トレッド内に注入するステップと、
・未硬化タイヤ及びインサートを担持したコアを規定されたアジマス角に沿って外部モールド内に位置決めするステップとを有する。
以下の説明における便宜上、ベースエラストマー材料を「ベースコンパウンド」(MB)と呼び、インサートを構成するこれとは異なるエラストマー材料を「挿入コンパウンド」(MI)と呼ぶ。
・インサートの横方向位置(タイヤの軸方向における)も又、挿入方法、特に、ノズルの軸方向位置及びその形状によって与えられる。
・最後に、コアに対するインサートの周方向位置(例えば、アジマス角α)は、例えば上述したような割出しシステムにより制御される。
