Seriously, unless your as old as Dolan, Desoto Man, or I you may not remember saw dust or ground walnut shell winter tires. Recappers mix it in the rubber compound and it offered excellent ice and snow traction. Only down side was poor wear. Studded tires ended there use. I am convinced we should revisit this technology. I am taking start up money from investors and expect to have 10 million shortly. I will take no salary for first three years , but will use all funds for R and D, production and the build of 500mph test vehicle stream liner. I expect the entire land speed community to get behind both the development of the tire and the stream liner. Thanks to all in advance for your suggestions and support. Yours in speed and safety, Racer Geo
