First Claim
Patent Images
1. A system for mounting a spike pin in a tread surface of a tire, comprising the combination of:
- a spike pin (3) made of a rubber material having a property of hardening at a low temperature,a tread surface (2) containing a recess (6), anda mounting arrangement in which said spike pin (3) is mounted with a gap (8) between the periphery of the spike pin and the peripheral wall of said recess, and with the top end of the spike pin being substantially flush with or recessed from the tread surface wherein on ice and snow surfaces, the spike pin can remain rigid while the tread deforms, thereby allowing the spike spin to protrude from the tread surface.
