wide wheels with rather narrow tires

[Erik Ringelberg]

All,

There is a ratio for width of tire and rim. Graph: On the same rim with 
increasing tire sizes there is a traction curve that declines to the right, 
with increasing comfort. It also falls off hard on the left when the tire 
width is not sufficient to deal with the heat of the car's cornering. So 
relative narrow is better, up to a point. It also reduces tramlining for a 
given rim width. (A wider tire will tram more.)

This is all theory. A stiff sidewall R-tire will work best at the widest 
width you can cram on. (see hoosier).
