Avoid odd-sized tires such as low profile tires and 16-inch truck tires.

The ideal type of tire used to fabricate rubber boards is a well-worn, 15-inch steel belted passenger tire. The lack of tread makes the tire more flexible and easier to work with, and 15-inch tires are a common size for passenger vehicles.

When a screw is inserted into a tire tread reinforced with steel belts, the strands of wire wrap around the screw, ensuring a secure fastening. Fortunately, the vast majority of tires manufactured today are steel reinforced. Sixteen-inch tires should be avoided, as they are less flexible due to their heavier build. Also avoid self-sealing tires, as the sealing compound is not compatible with gardening. And avoid low profile tires, as they tend to be stiff and inflexible.

A simple elevated workbench for extra long rubber boards.

Several types of power tools are required to fabricate rubber boards. A power drill equipped with a Phillips head bit will speed up the fastening process. A grinder does quick work removing any screw tips protruding from the sides of rubber boards. A chop/cut-off saw works best to prepare large numbers of rebar sections.

A jigsaw serves to slice and dice the tires. Steel reinforced tire tread is easily cut using a jigsaw equipped with a metal cutting or hacksaw blade. For easier cutting, choose a saw with a high reciprocating speed. Purchase only fine-toothed blades for smooth cutting. We have good results using blades with 18 teeth per inch (TPI).

Use a workbench when fabricating large numbers of boards. For extra long boards, use 2-inch by 12-inch lumber supported by saw horses or concrete blocks as a working surface. Protruding screw tips can damage your workbench surface, so it's a good idea to cover the surface with a piece of particleboard.
