We understand that sometimes you need to put your ideas into motion to get the design just right. That’s why we’ve come up with a way to put your innovation to the test. We offer a line of pre-ground tires in various sizes and durometers to choose from. They are easy to assemble to your existing shaft. Once you’ve proven out your design, call us to order production or prototype parts made complete to print.
We will work with you throughout the development process to bring your concept from plan to product launch, and will take on the work of assembly and grinding to the finished dimensions.
