Comparing a 32mm tire at 120 PSI & a 23mm tire at 60 PSI?
Comparing different width tires at the SAME PRESSURE!
Rolling resistance tests on a 20" diameter roller instead of FLAT pavement, totally altering the shape of the contact patch. Ya think that might favor a more supple sidewall?

None of you would be allowed to work for me.
