A basic tire tread strip product is reclaimed from tire carcasses by cutting away and discarding opposed sidewalls at a position leaving a flat central tread portion exclusive of resiliently biased downwardly extending tread portions at outer edges, thereby to form a product that lies flat on utility surfaces including roofs, floors, roadways and multilayered tread strips forming beams and parking stops. This product ideally serves as a rumble strip for adhering to flat roadway surfaces as a tough, long-wearing structure that encounters vehicle wheels with a distinctive audible warning signal, particularly since it can be removed and reused for example in the winter time to avoid being damaged by snow plows. Also tread strip laminations ideally rest flatly on top of each other to form multi-layered beams of precision widths of the type that may be employed as parking stops for statically intercepting and impeding vehicle wheels in parking lot locations for example.
