Abstract
MÉTODO DE TESTE DA RESISTÊNCIA DE UM PNEU A UMA PERDA DE PRESSÃO. Método de teste da resistência de um pneu a uma perda de pressão seguida de uma perfuração, caracterizado pelo fato de que inclui as seguintes etapas: -criar na parede do pneu uma série de perfurações inserindo através de tal parede uma série de objetos perfurantes; -rodar o pneu incluindo os objetos perfurantes por uma distância determinada com uma pressão de inflação regulada; -parar a rodagem; e determinar para cada perfuração um índice de resistência à perda de pressão baseado em uma estimativa do fluxo de fuga da perfuração.
