People agonize over the little things and ignore the major factor that will offset any gains.

Don’t forget that there are hills. Aerodynamics is scarcely a factor on steeper grades, so it’s hard work against gravity plus rolling friction. The difference of two slow tires could be as much 30 watts. I typically do 300-325 watts up our hills, and I would much rather put as much of that as possible into speed up a hill than dissipate it in slow tires. As an example, my 26x2.2 Race Kings are rated about 20W per tire, while there are MTB tires at more like 35W per tire.
