7 inch to 205-225
7.5 to 215-235
8 to 225-245
8.5 to 235-255 and so on.
Does such an equation exist?
A Dunlop tire tech once told me that max steering response came from a wheel that was exactly the width of the tread. Narrower rims softened the ride and steering response. So, for the OEM RE050s, the tread is 7.4", so the better rim would be 7.5". I wonder is there is a detectable difference on a 7" rim.
Indeed for racing, autocross or track, we like to run wheels same width as the tire for max steering response and contact patch stability. But in the real world this has downsides including ride and curb rash potential.
