The traction tires are 1/2" wide sections of the same rubber used on the VersaWheel DT only slightly softer. CoF with the FRC carpet will be put up on the website in the next few days, but it is similar to Colson Wheels.

The tread was pulled last year because it did not perform to our expectations. While the tires looked great and had very high CoF with the FRC carpet, the rubber was too soft and would peel off of the wheel during turning. Our main goal was to not have to use any sort of fastener to hold this tire on the wheel so after several attempts to fix the problem we decided to scrap the entire design.

This year's tread has an injection molded plastic support ring inside the rubber material to eliminate the possibility of peeling. This tire has great traction and allows you the flexibility to make pretty much any wheel width you want.
