I think the forward traction discussion is dead. I've seen mid cars run the fastest laps on very loose surfaces. This coming from a guy who still runs RM.
What gives you the idea that a narrower tire can yield more side-bite? I am not aware of a situation outside of snow/ice where this is possible.
