TeacherGeek rubber stretch tires are flexible, durable extrusions for kinetic STEM | STEAM projects. Stretch these custom, natural rubber bands over wheel hubs to improve traction or experiment with friction. Applying a glue stick to the wheel surface prior to installation helps keeps the tires in place. The elastic is sturdy, resisting wear over time and countless stretches, allowing for dozens of design changes and do-overs in your engineering process. An excellent choice for rubber band racers, mousetrap vehicles, yeast mobiles, electric racers and sail cars.
Note: These are not just average rubber bands. The tires are designed to work exclusively with our components.
