I have had so many requests for this and here it is; A quarter size wheel and tyre for the 2023 season.

This is the (Yellow) Medium tyre, but I can do the (Red) Soft and (White) Hard upon request.
The parts are 3D printed and then polished and rubberized, with stickers added to finish it off.
The wheel sits perfectly on the stand supplied, and will not rock or roll once in position.
