True. And these days, "wider is faster" is the cycling myth in need of getting corrected. Because is mostly a tie, with a very soft optimum between clearly worse extremes (neither 10 mm nor 10 inch would be fast). And people who feel in the mood for "overthrowing the old" will often do comparisons were they lower pressure on the wider tires, but don't really lower then adequately, they compare a narrow tire at the lowest and of its useable pressure range to a wider tire at the high end of its range and, surprise, with these conditions the wide one rolls easier. The assumed optimum has shifted, but it hasn't run away.
