Duniop : Here is an illustration, General, of my point about 
steel non-skids for ambulances and staff cars. How 
would rubber barbed wire work ? 
The General : Wouldn't hold anything ! 
Duniop: Exactly; and a cover with rubber barbs, so to 
speak, won't hold your car on grease. Rubber doesn't 
bite through to solid ground ; steel does. On the other 
hand, rubber will hold on a surface where steel would slip. 
The General : So you recommend ? 
Duniop: Steel-studded covers on the near-back and off- 
front wheels and grooved rubber covers on the other 
two. It is the best all-round arrangement for varying 
road surfaces and weather conditions.
