I am involved in the recycled industry and ground up tires are what we call "crumbed rubber". There are many varieties of rubber crumb as there are many varieties of rubber. The rubber is cured with different chemicals when it is made, and there is seldom little, if any, cleansing of the recycled material before or after it is crumbed. So, you get whatever was mixed in with the tires when it goes into the crumber. (wire, glass, dirt, metal,et.) Just for jollies, search crumb rubber on the NET and look for yourselves. I believe that you would need to get SBR rubber in a large crumb size, ie. 4 - 10 mm in order for orchids to begin to drain properly. Personally, I would stay away from the idea unless you know where your rubber has been... Tim
