SLIP PREVENTING APPARATUS FOR CAR TIRE

Title:

SLIP PREVENTING APPARATUS FOR CAR TIRE

Document Type and Number:

Japanese Patent JPS6118506

Kind Code:

A

Abstract:

PURPOSE:To reduce the abrasion of a spike pin by forming the rubber layer of the lower side part for supporting the basic part of the spike pin from the rubber softer than the rubber hardness, in a spike tire. CONSTITUTION:A supporting ring-band 4 for spike pins 2 is formed integrally, with each different rubber hardness of the lower and upper layers 4' and 4'', having the vicinity of the basic part of the spike pin 2 as boundary, and each rubber hardness of a tire 1 and the lower and upper layers 4' and 4'' is set at 5:3:6 in the representation of the ratio in 10 stages. With such constitution, the immersion of spike pins 2 is enabled by the deformation of the rubber of the lower layer 4' softer than the tire hardness on contact with a hard road surface, without deteriorating the slip preventing effect of the spike tire, and the abrasion of the spike pin can be reduced.
