I have found that it's pretty impossible to convince those in either camp to give up what they like best, whether it's the skinny or the fat-tire crowd (fwiw, I'm in the latter camp). It seems a matter of ideology given the gazillion variables that would affect perceptions of how a bike rides. I'm just glad the tires I like to ride are readily available (really an explosion of availability in 700 x 32mm; I'm riding some new Continental GP 5000s on the road bike I use most often, and they are terrific).
