John;
For years people have been coming up with various schemes for replacing the
pneumatic tire (tyre for Malcolm) but those have never been completely
satisfactory-- for various reasons.
One of the most important features of the pneumatic tire is its ability to
generate tread distortion when run at an angle; this "slip angle" creates a
restoring torque, generating the lateral force necessary to go around a
corner.
Going back to forklifts (no, not RWS) those solid rubber tires are
miserable to drive and have a pretty short life. Their ability to transfer
every bump and vibration to the chassis is almost nil. Keeping the
wheel/tire combination in contact with the ground will be a problem with the
solid urethane tire approach, I suspect.
This seems to be a "semi-solid wheel". I'd suggest approaching higher speeds
in small steps as handling problems might show up with these that had not
been apparent with standard pneumatic tires.

Other than making the wheels , does anybody know any reason why the Chet
Herbert idea of using tooth belts for tires is not a good ?
