really struggling to find a poly-wheel match but will keep on trying
Check the guys running Go-Karts in Kal. Once the tyres go off, they are about as handy as a wrought iron hang glider. These will fit a PVC pipe size. We used to use PVC pipe to store them while in transit.
Most will give you the old tyres for nix, just to get shod of them. They will probably drift like crazy without PVC as they go very hard with temp range and age.
The rims are not expensive either.
