Title: Spike tire
Inventor: HASHIMOTO TAKATSUGU
IPC: B60C11/16
Filed: 1985-09-06
Abstract: PURPOSE:To prevent the breakage of a road surface by installing a rubber elastic body into which water is sealed in liquidtight form at the basic edge part of a spike installed into a treat part, thus reducing the modulus of water in the case when a road surface is not in frozen state and permitting the spike to retreat into the tire. CONSTITUTION:A spike tire is formed by burying a number of shanks (spike) 1 having a flange 2 at the basic edge part into a tread part 6, and a tip 3 is installed at the top edge part of the shank 1. In this case, a rubber elastic body 4 which contains water in liquidtight form is installed onto the edge surface on the basic edge side of the shank 1, namely on the side where the flange 2 is installed. Therefore, when a road surface is not in frozen state, the temperature of the tire becomes over the meling point of water, and the elastic modulus of water is kept sufficiently small, and the shank 1 can freely retreat into the tire by the pressing force in the direction of retreat by the contact with the road surface. Therefore, in this state, the breakage of the road surface due to the tip 3 can be prevented exceedingly efficiently.
