The 9" foam-filled drive wheel assembly for the Go-Go Go Chair features a black PU foam-filled tire on a Tri-spoke Euro Gray rim. Foam-filled mean that it is flat-free.
Note: This 9" wheel assembly is only compatible with 2016 and newer Go-Go Go Chair. If your Go Chair is an earlier model you will want the 2.5"x7.5" Flat-Free Drive Wheel Assembly.
Easy installation, the foam filled tires significantly reduces the impact felt every time one crosses a joint in sidewalks when using solid rubber tires. These foam filled tires help a lot with my chronic back pain.
