Do you have data for that? Clearly an increase in wheel width (holding section width constant) increases the spring rate of the sidewall and steepens the cornering force vs slip angle slope; i.e. makes the tire more responsive to transient inputs.
However, do you have empirical data on identical tires showing a decrease in maximum cornering force with increase in rim width (staying within the TRA rim width window for the tire size of course)? I've only seen the opposite of that, so I'm curious what data you're referring to.
