Problem is that there's a lot of variables to consider (ie; air pressure, sidewall height, tire ratings, ets,etc).

A wider tire will not put more rubber on the road (althought it is commonly thought it would), there is less PSI on the tire (not air pressure) so the lateral contact patch will shrink. The footprint of the tire then becomes wider but shorter with a wide tire. Its a ratio if you shrink it one way, it grows the other way.
